Terms, Icons, and Labels

Many classes have shortcut names used when creating (instantiating) a class with a configuration object. The shortcut name is referred to as an alias (or xtype if the class extends Ext.Component). The alias/xtype is listed next to the class name of applicable classes for quick reference.

Access Levels

Framework classes or their members may be specified as private or protected. Else, the class / member is public. Public, protected, and private are access descriptors used to convey how and when the class or class member should be used.

Member Types

Member Syntax

Below is an example class member that we can disect to show the syntax of a class member (the lookupComponent method as viewed from the Ext.button.Button class in this case).

lookupComponent ( item ) : Ext.Component
protected

Called when a raw config object is added to this container either during initialization of the items config, or when new items are added), or {@link #insert inserted.

This method converts the passed object into an instanced child component.

This may be overridden in subclasses when special processing needs to be applied to child creation.

Parameters

item :  Object

The config object being added.

Returns
Ext.Component

The component to be added.

Let's look at each part of the member row:

Member Flags

The API documentation uses a number of flags to further commnicate the class member's function and intent. The label may be represented by a text label, an abbreviation, or an icon.

Class Icons

- Indicates a framework class

- A singleton framework class. *See the singleton flag for more information

- A component-type framework class (any class within the Ext JS framework that extends Ext.Component)

- Indicates that the class, member, or guide is new in the currently viewed version

Member Icons

- Indicates a class member of type config

- Indicates a class member of type property

- Indicates a class member of type method

- Indicates a class member of type event

- Indicates a class member of type theme variable

- Indicates a class member of type theme mixin

- Indicates that the class, member, or guide is new in the currently viewed version

Class Member Quick-Nav Menu

Just below the class name on an API doc page is a row of buttons corresponding to the types of members owned by the current class. Each button shows a count of members by type (this count is updated as filters are applied). Clicking the button will navigate you to that member section. Hovering over the member-type button will reveal a popup menu of all members of that type for quick navigation.

Getter and Setter Methods

Getting and setter methods that correlate to a class config option will show up in the methods section as well as in the configs section of both the API doc and the member-type menus just beneath the config they work with. The getter and setter method documentation will be found in the config row for easy reference.

History Bar

Your page history is kept in localstorage and displayed (using the available real estate) just below the top title bar. By default, the only search results shown are the pages matching the product / version you're currently viewing. You can expand what is displayed by clicking on the button on the right-hand side of the history bar and choosing the "All" radio option. This will show all recent pages in the history bar for all products / versions.

Within the history config menu you will also see a listing of your recent page visits. The results are filtered by the "Current Product / Version" and "All" radio options. Clicking on the button will clear the history bar as well as the history kept in local storage.

If "All" is selected in the history config menu the checkbox option for "Show product details in the history bar" will be enabled. When checked, the product/version for each historic page will show alongside the page name in the history bar. Hovering the cursor over the page names in the history bar will also show the product/version as a tooltip.

Search and Filters

Both API docs and guides can be searched for using the search field at the top of the page.

On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page.

The checkbox at the bottom of the API class navigation tree filters the class list to include or exclude private classes.

Clicking on an empty search field will show your last 10 searches for quick navigation.

API Doc Class Metadata

Each API doc page (with the exception of Javascript primitives pages) has a menu view of metadata relating to that class. This metadata view will have one or more of the following:

Expanding and Collapsing Examples and Class Members

Runnable examples (Fiddles) are expanded on a page by default. You can collapse and expand example code blocks individually using the arrow on the top-left of the code block. You can also toggle the collapse state of all examples using the toggle button on the top-right of the page. The toggle-all state will be remembered between page loads.

Class members are collapsed on a page by default. You can expand and collapse members using the arrow icon on the left of the member row or globally using the expand / collapse all toggle button top-right.

Desktop -vs- Mobile View

Viewing the docs on narrower screens or browsers will result in a view optimized for a smaller form factor. The primary differences between the desktop and "mobile" view are:

Viewing the Class Source

The class source can be viewed by clicking on the class name at the top of an API doc page. The source for class members can be viewed by clicking on the "view source" link on the right-hand side of the member row.

Ext.calendar.view.Weeks xtype: calendar-weeksview premium

Summary

For an overview of calendar views see Ext.calendar.view.Base

The Weeks view shows the events for one or more weeks as full days similar to a conventional calendar. For a week view including an hourly timeline see Ext.calendar.view.Week.

The weeks view shows the week containing the current date (or the date set on the value config) plus any additional weeks totaling the visibleWeeks. The number of days shown per week is set using visibleDays. Each week begins on the day set on the firstDayOfWeek.

By default the first day is Sunday. If you want to create a "work week" type view where the weekend days are omitted you can modify the visibleDays and firstDayOfWeek to show only Monday - Friday.

Ext.create({
    xtype: 'calendar-weeksview',
    renderTo: Ext.getBody(),
    height: 400,
    width: 400,
    firstDayOfWeek: 1,  // starts the view on Monday
    visibleDays: 5,     // and displays it and the 4 days after
    store: {
        autoLoad: true,
        proxy: {
            type: 'ajax',
            url: 'calendars.php'
        },
        eventStoreDefaults: {
            proxy: {
                type: 'ajax',
                url: 'events.php'
            }
        }
    }
});

Calendar Events

Events show on the view with their start and end days correlating to the day labels. The events will display on the timeline according to your local timezone offset from GMT. The timezone offset can be applied explicitly using the timezoneOffset config option.

Adding All Day Events

Dragging / swiping across multiple days will show the event add form with multiple days pre-populated in the form's start / end dates. A single all day type event can be added by tapping / clicking on a single day.

Date Range Navigation

The movePrevious and moveNext methods modify the displayed date range by moving the range forward or backward the number of visibleWeeks.

i.e. view.moveNext(); called on a 7-day view with 2 visible weeks will advance the view 2 weeks. Note that a view configured with 5 visibleDays would not advance 5 days, but rather will show the next full week with only 5 visible days.

Alternative Classes

If your view requires a header showing the days of the week consider using Ext.calendar.panel.Weeks instead. For a month view refer to Ext.calendar.view.Month.

A flag indicating that this component should be above its floated siblings.

This may be a positive number to prioritize the ordering of multiple visible always on top components.

This may be set to a negative number to prioritize a component to the bottom of the z-index stack.

Defaults to:

false

Available since: 6.2.0

getAlwaysOnTop : Boolean / Number

Returns the value of alwaysOnTop

Returns

Boolean / Number

setAlwaysOnTop (alwaysOnTop)

Parameters

alwaysOnTop :  Boolean / Number

ariaAttributes : Object
bindable bind

An object containing ARIA attributes to be set on this Component's ARIA element. Use this to set the attributes that cannot be determined by the Component's state, such as aria-live, aria-flowto, etc.

Note that this config is only meaningful at the Component rendering time, and setting it after that will do nothing.

Defaults to:

null

getAriaAttributes : Object

Returns the value of ariaAttributes

Returns

Object

setAriaAttributes (ariaAttributes)

Sets the value of ariaAttributes

Parameters

ariaAttributes :  Object

ariaDescribedBy : String

DOM selector for a child element that is to be used as description for this Component, set in aria-describedby attribute. The selector works the same way as ariaLabelledBy.

ariaLabel : String

ARIA label for this Component. It is best to use ariaLabelledBy option instead, because screen readers prefer aria-labelledby attribute to aria-label. ariaLabel and ariaLabelledBy config options are mutually exclusive.

ariaLabelledBy : String

DOM selector for a child element that is to be used as label for this Component, set in aria-labelledby attribute. If the selector is by id, the label element can be any existing element, not necessarily a child of the main Component element.

ariaLabelledBy and ariaLabel config options are mutually exclusive, and ariaLabelledBy has the higher precedence.

axisLock : Boolean
bindable bind

If true, then, when showBy or alignTo fallback on constraint violation only takes place along the major align axis.

That is, if alignment "l-r" is being used, and axisLock: true is used, then if constraints fail, only fallback to "r-l" is considered.

Defaults to:

null

getAxisLock : Boolean

Returns the value of axisLock

Returns

Boolean

setAxisLock (axisLock)

Sets the value of axisLock

Parameters

axisLock :  Boolean

bind : Object / String
bindable bind

Setting this config option adds or removes data bindings for other configs. For example, to bind the title config:

 var panel = Ext.create({
     xtype: 'panel',
     bind: {
         title: 'Hello {user.name}'
     }
 });

To dynamically add bindings:

 panel.setBind({
     title: 'Greetings {user.name}!'
 });

To remove bindings:

 panel.setBind({
     title: null
 });

The bind expressions are presented to Ext.app.ViewModel#bind. The ViewModel instance is determined by lookupViewModel.

Note: If bind is passed as a string, it will use the Ext.Component#property-defaultBindProperty for the binding.

Defaults to:

null

getBind : Object / String

Returns the value of bind

Returns

Object / String

setBind (bind)

Sets the value of bind

Parameters

bind :  Object / String

border : Boolean
bindable bind

Enables or disables bordering on this component. The following values are accepted:

  • null or `true (default): Do nothing and allow the border to be specified by the theme.
  • false: suppress the default border provided by the theme.

Please note that enabling bordering via this config will not add a border-color or border-style CSS property to the component; you provide the border-color and border-style via CSS rule or style configuration (if not already provide by the theme).

Using style:

Ext.Viewport.add({
    centered: true,
    width: 100,
    height: 100,

    style: 'border: 1px solid blue;'
    // ...

Returns the value of bottom

Returns

Number / String

setBottom (bottom)

Sets the value of bottom

Parameters

Defaults to:

undefined

getFirstDayOfWeek : Number

Returns the value of firstDayOfWeek

Returns

Number

setFirstDayOfWeek (firstDayOfWeek)

Sets the value of firstDayOfWeek

Parameters

firstDayOfWeek :  Number

flex : Number / String / Object
bindable bind

The flex of this item if this item item is inside a Ext.layout.HBox or Ext.layout.VBox layout.

You can also update the flex of a component dynamically using the Ext.layout.FlexBox#setItemFlex method.

When supplied as a string or number this option supports the same syntax as CSS flex. For example:

flex: '1 2 auto'

sets flex-grow property to 0, flex-shrink to 2 and flex-basis to 'auto'.

The default flex-shrink value for box layout items is set to 0 in the stylesheet, which is different from the browser's default flex-shrink value of 1. This accommodates the majority use case for applications since where non-flexed components are typically not expected to shrink smaller than their default size.

For convenience when only a single number is supplied it is used as the value for both flex-grow and flex-shrink, for example flex: 3 is the same as flex: '3 3'

An object form is also accepted:

flex: {
    grow: 1,
    shrink: 2,
    basis: 'auto'
}

When the object form is supplied shrink always defaults to 0 regardless of the value of grow.

Although 'auto' is the default value for flex-basis, flex-basis defaults to 0% when flex is supplied as a single numeric or string value (e.g. flex: 1). If this behavior is not desired either explicitly set flex-basis to 'auto' or use the object form to set only grow and/or shrink:

flex: {
    grow: 2
}

Defaults to:

null

getFlex : Number / String / Object

Returns the value of flex

Returns

Number / String / Object

setFlex (flex)

Sets the value of flex

Parameters

flex :  Number / String / Object

floated : Boolean
bindable bind

A Component may be floated above all other components in the application. This means that the component is absolutely positioned, and will move to the front and occlude other sibling floated component if clicked.

A Floated component may have floated descendants. It will bring these decendants to the front with it when brought to the front of its sibling floated components.

By default, descendant floated components are all positioned using the viewport coordinate system. To make a floating component a positioning parent for descendants, and have the ancestors positioned relatively, configure the parent floated component with cfg-relative: true.

id : String

The unique id of this component instance.

It should not be necessary to use this configuration except for singleton objects in your application. Components created with an id may be accessed globally using Ext.getCmp.

Instead of using assigned ids, use the itemId config, and Ext.ComponentQuery which provides selector-based searching for Sencha Components analogous to DOM querying. The Ext.Container class contains shortcut methods to query its descendant Components by selector.

Note that this id will also be used as the element id for the containing HTML element that is rendered to the page for this component. This allows you to write id-based CSS rules to style the specific instance of this component uniquely, and also to select sub-elements using this component's id as the parent.

Note: to avoid complications imposed by a unique id also see itemId.

Defaults to an auto-assigned id.

getId String

Retrieves the id of this component. Will autogenerate an id if one has not already been set.

Returns

:String

id

instanceCls : String / String[]
bindable bind private pri

An extra CSS class or classes to augment the classCls on an individual instance

Defaults to:

null

Available since: 6.5.0

getInstanceCls : String / String[]

Returns the value of instanceCls

Returns

String / String[]

setInstanceCls (instanceCls)

Sets the value of instanceCls

Parameters

instanceCls :  String / String[]

itemId : String
bindable bind

An itemId can be used as an alternative way to get a reference to a component when no object reference is available. Instead of using an id with Ext#getCmp, use itemId with Ext.Container#getComponent which will retrieve itemId's or id's. Since itemId's are an index to the container's internal MixedCollection, the itemId is scoped locally to the container - avoiding potential conflicts with Ext.ComponentManager which requires a unique id.

Also see id, Ext.Container#query, Ext.Container#down and Ext.Container#child.

Defaults to:

undefined

getItemId : String

Returns the value of itemId

Returns

String

setItemId (itemId)

Sets the value of itemId

Parameters

itemId :  String

keyMap : Object
bindable bind

An object containing handlers for keyboard events. The property names of this object are the key name and any modifiers. The values of the properties are the descriptors of how to handle each event.

The handler descriptor can be simply the handler function (either the literal function or the method name), or it can be an object with these properties:

  • handler: The function or its name to call to handle the event.
  • scope: The this pointer context (can be "this" or "controller").
  • event: An optional override of the key event to which to listen.

Important: Calls to setKeyMap do not replace the entire keyMap but instead update the provided mappings. That is, unless null is passed as the value of the keyMap which will clear the keyMap of all entries.

Defaults to:

null

Properties

scope : String

The default scope to apply to key handlers which do not specify a scope. This is processed the same way as the scope of cfg-listeners. It defaults to the "controller", but using 'this' means that an instance method will be used.

getKeyMap : Object

Returns the value of keyMap

Returns

Object

setKeyMap (keyMap)

Sets the value of keyMap

Parameters

keyMap :  Object

keyMapEnabled : Boolean
bindable bind

Enables or disables processing keys in the keyMap. This value starts as null and if it is null when initKeyMap is called, it will automatically be set to true. Since initKeyMap is called by Ext.Component at the proper time, this is not something application code normally handles.

Defaults to:

null

getKeyMapEnabled : Boolean

Returns the value of keyMapEnabled

Returns

Boolean

setKeyMapEnabled (keyMapEnabled)

Sets the value of keyMapEnabled

Parameters

keyMapEnabled :  Boolean

keyMapTarget : String
protected pro

The name of the member that should be used to listen for keydown/keypress events. This is intended to be controlled at the class level not per instance.

Defaults to:

'el'

left : Number / String
bindable bind

The absolute left position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component become 'positioned', which means it will no longer participate in the layout of the Container that it resides in.

Defaults to:

null

getLeft : Number / String

Returns the value of left

Returns

Number / String

setLeft (left)

Sets the value of left

Parameters

left :  Number / String

listeners : Object
bindable bind

A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once.

DOM events from Ext JS Ext.Component

While some Ext JS Component classes export selected DOM events (e.g. "click", "mouseover" etc), this is usually only done when extra value can be added. For example the DataView's itemclick event passing the node clicked on. To access DOM events directly from a child element of a Component, we need to specify the element option to identify the Component property to add a DOM listener to:

new Ext.panel.Panel({
    width: 400,
    height: 200,
    dockedItems: [{
        xtype: 'toolbar'
    }],
    listeners: {
        click: {
            element: 'el', //bind to the underlying el property on the panel
            fn: function(){ console.log('click el'); }
        },
        dblclick: {
            element: 'body', //bind to the underlying body property on the panel
            fn: function(){ console.log('dblclick body'); }
        }
    }
});

setListeners ( listeners )

An alias for addListener. In versions prior to 5.1, listeners had a generated setter which could be called to add listeners. In 5.1 the listeners config is not processed using the config system and has no generated setter, so this method is provided for backward compatibility. The preferred way of adding listeners is to use the on method.

Parameters

listeners :  Object

The listeners

margin : Number / String

Defaults to:

null

getModal : Boolean

Returns the value of modal

Returns

Boolean

setModal (modal)

Sets the value of modal

Parameters

modal :  Boolean

modelValidation : Boolean

This config enables binding to your Ext.data.Model#validators. This is only processed by form fields (e.g., Ext.field.*) at present, however, this setting is inherited and so can be set on a parent container.

When set to true by a component (or by an ancestor container), the validators of for any {@Ext.data.Model record} fields will be used wherever the value is bound to such data fields.

While this config can be set arbitrarily high in the component hierarchy, doing so can create a lot overhead if most of your form fields do not actually rely on validators in your data model.

Using this setting for a form that is bound to an Ext.data.Model might look like this:

 {
     xtype: 'panel',
     modelValidation: true,
     items: [{
         xtype: 'textfield',
         bind: '{theUser.firstName}'
     },{
         xtype: 'textfield',
         bind: '{theUser.lastName}'
     },{
         xtype: 'textfield',
         bind: '{theUser.phoneNumber}'
     },{
         xtype: 'textfield',
         bind: '{theUser.email}'
     }]
 }

Defaults to:

null

Available since: 6.5.0

name : String

Name for the widget to be used with Ext.Container#lookupName et al.

Defaults to:

null

nameable : Boolean

Set to true for this component's name property to be tracked by its containing nameHolder.

Defaults to:

false

overflowText : String
bindable bind

Text to show when events overflow on a particular day to allow the user to view the rest. This string is evaluated as a formatted string where the argument is the number of overflowing events. Depends on showOverflow.

Defaults to:

'+{0} more'

getOverflowText : String

Returns the value of overflowText

Returns

String

setOverflowText (overflowText)

Sets the value of overflowText

Parameters

overflowText :  String

padding : Number / String
bindable bind

Defaults to:

null

getPadding : Number / String

Returns the value of padding

Returns

Number / String

setPadding (padding)

Sets the value of padding

Parameters

padding :  Number / String

plugins : Array / Ext.enums.Plugin / Object / Ext.plugin.Abstract
bindable bind

This config describes one or more plugin config objects used to create plugin instances for this component.

Plugins are a way to bundle and reuse custom functionality. Plugins should extend Ext.plugin.Abstract but technically the only requirement for a valid plugin is that it contain an init method that accepts a reference to its owner. Once a plugin is created, the owner will call the init method, passing a reference to itself. Each plugin can then call methods or respond to events on its owner as needed to provide its functionality.

This config's value can take several different forms.

The value can be a single string with the plugin's Ext.enums.Plugin:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: 'listpaging'
 });

In the above examples, the string "listpaging" is the type alias for Ext.dataview.plugin.ListPaging. The full alias includes the "plugin." prefix (i.e., 'plugin.listpaging').

The preferred form for multiple plugins or to configure plugins is the keyed-object form (new in version 6.5):

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: {
         pullrefresh: true,
         listpaging: {
             autoPaging: true,
             weight: 10
         }
     }
 });

The object keys are the id's as well as the default type alias. This form allows the value of the plugins to be merged from base class to derived class and finally with the instance configuration. This allows classes to define a set of plugins that derived classes or instantiators can further configure or disable. This merge behavior is a feature of the config.

The plugins config can also be an array of plugin aliases (arrays are not merged so this form does not respect plugins defined by the class author):

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: ['listpaging', 'pullrefresh']
 });

An array can also contain elements that are config objects with a type property holding the type alias:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: ['pullrefresh', {
         type: 'listpaging',
         autoPaging: true
     }]
 });

Defaults to:

null

setPlugins (plugins)

Sets the value of plugins

Parameters

plugins :  Array / Ext.enums.Plugin / Object / Ext.plugin.Abstract

publishes : String / String[] / Object
bindable bind

One or more names of config properties that this component should publish to its ViewModel. Generally speaking, only properties defined in a class config block (including ancestor config blocks and mixins) are eligible for publishing to the viewModel. Some components override this and publish their most useful configs by default.

Note: We'll discuss publishing properties not found in the config block below.

Values determined to be invalid by component (often form fields and model validations) will not be published to the ViewModel.

This config uses the cfg-reference to determine the name of the data object to place in the ViewModel. If reference is not set then this config is ignored.

By using this config and cfg-reference you can bind configs between components. For example:

 ...
     items: [{
         xtype: 'textfield',
         reference: 'somefield',  // component's name in the ViewModel
         publishes: 'value' // value is not published by default
     },{
         ...
     },{
         xtype: 'displayfield',
         bind: 'You have entered "{somefield.value}"'
     }]
 ...

Classes must provide this config as an Object:

 Ext.define('App.foo.Bar', {
     publishes: {
         foo: true,
         bar: true
     }
 });

This is required for the config system to properly merge values from derived classes.

For instances this value can be specified as a value as show above or an array or object as follows:

 {
     xtype: 'textfield',
     reference: 'somefield',
     publishes: [
         'value',
         'rawValue',
         'dirty'
     ]
 }

 // This achieves the same result as the above array form.
 {
     xtype: 'textfield',
     reference: 'somefield',
     publishes: {
         value: true,
         rawValue: true,
         dirty: true
     }
 }

In some cases, users may want to publish a property to the viewModel that is not found in a class config block. In these situations, you may utilize publishState if the property has a setter method. Let's use setFieldLabel as an example:

  setFieldLabel: function(fieldLabel) {
      this.callParent(arguments);
      this.publishState('fieldLabel', fieldLabel);
  }

With the above chunk of code, fieldLabel may now be published to the viewModel.

null

tooltip : String / Object
bindable bind

The tooltip for this component - can be a string to be used as innerHTML (html tags are accepted) or Ext.tip.ToolTip config object.

The default behavior is to use a shared tip instance. The tooltip configuration is registered with the Ext.tip.Manager. To enable this, your application can set the Ext.app.Application#quickTips config, or an instance of the Ext.tip.Manager may be created manually.

To force a unique tooltip instance to be created, specify autoCreate: true on this configuration.

Configuring this with autoHide: false implies autoCreate: true so that the desired persistent behavior can be obtained with other targets still showing the singleton instance.

Defaults to:

null

getTooltip : String / Object

Returns the value of tooltip

Returns

String / Object

setTooltip (tooltip)

Sets the value of tooltip

Parameters

tooltip :  String / Object

top : Number / String
bindable bind

The absolute top position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component become 'positioned', which means it will no longer participate in the layout of the Container that it resides in.

Defaults to:

null

getTop : Number / String

Returns the value of top

Returns

Number / String

setTop (top)

Sets the value of top

Parameters

top :  Number / String

touchAction : Object
bindable bind

Emulates the behavior of the CSS touch-action property in a cross-browser compatible manner.

Keys in this object are touch action names, and values are false to disable a touch action or true to enable it. Accepted keys are:

  • panX
  • panY
  • pinchZoom
  • doubleTapZoom

All touch actions are enabled (true) by default, so it is usually only necessary to specify which touch actions to disable. For example, the following disables only horizontal scrolling and pinch-to-zoom on the component's main element:

touchAction: {
    panX: false,
    pinchZoom: false
}

Touch actions can be specified on reference elements using the reference element name, for example:

// disables horizontal scrolling on the main element, and double-tap-zoom
// on the child element named "body"
touchAction: {
    panY: false
    body: {
        doubleTapZoom: false
    }
}

The primary motivation for setting the touch-action of an element is to prevent the browser's default handling of a gesture such as pinch-to-zoom, or drag-to-scroll, so that the application can implement its own handling of that gesture on the element. Suppose, for example, a component has a custom drag handler on its element and wishes to prevent horizontal scrolling of its container while it is being dragged:

Ext.create('Ext.Widget', {
    touchAction: {
        panX: false
    },
    listeners: {
        drag: function(e) {
            // implement drag logic
        }
    }
});

Defaults to:

null

getTouchAction : Object

Returns the value of touchAction

Returns

Object

setTouchAction (touchAction)

Sets the value of touchAction

Parameters

touchAction :  Object

Sets the value of translatable

Parameters

translatable :  Object

twoWayBindable : String / String[] / Object
bindable bind

This object holds a map of config properties that will update their binding as they are modified. For example, value is a key added by form fields. The form of this config is the same as publishes.

This config is defined so that updaters are not created and added for all bound properties since most cannot be modified by the end-user and hence are not appropriate for two-way binding.

Defaults to:

null

getTwoWayBindable : String / String[] / Object

Returns the value of twoWayBindable

Returns

String / String[] / Object

setTwoWayBindable (twoWayBindable)

Sets the value of twoWayBindable

Parameters

twoWayBindable :  String / String[] / Object

ui : String / String[]
bindable bind

The ui or uis to be used on this Component

When a ui is configured, CSS class names are added to the element, created by appending the ui name(s) to each classCls and/or baseCls.

Defaults to:

null

getUi : String / String[]

Returns the value of ui

Returns

String / String[]

setUi (ui)

Sets the value of ui

Parameters

ui :  String / String[]

userCls : String / String[]
bindable bind

One or more CSS classes to add to the component's primary element. This config is intended solely for use by the component instantiator (the "user"), not by derived classes.

For example:

 items: [{
     xtype: 'button',
     userCls: 'my-button'
 ...
 }]

Defaults to:

null

getUserCls : String / String[]

Returns the value of userCls

Returns

String / String[]

setUserCls (userCls)

Sets the value of userCls

Parameters

userCls :  String / String[]

userSelectable : Boolean / String / Object
bindable bind

Set to true to allow users to select text within this component.

Can also be any valid value for the CSS3 user-select property.

A value of true implies auto, while false implies none.

May also be an object keyed by child element name.

By default, the user cannot click+drag+select text/elements of the UI. Applications may want to enable user selection for specific DOM elements, such as the bodyElement of a component used as a tab panel. The tab and tab text would not be user selectable in this example, but the content area when the tab is selected would.

 userSelectable: {
     element: true,       // optionally allow the element to be user selectable
     bodyElement: true    // optionally allow the component's body element to be user selectable
 }

Defaults to:

false

Available since: 6.5.1

getUserSelectable : Boolean / String / Object

Returns the value of userSelectable

Returns

Boolean / String / Object

setUserSelectable (userSelectable)

Sets the value of userSelectable

Parameters

userSelectable :  Boolean / String / Object

 {
     firstDayOfWeek: 0, // Sunday
     value: new Date(2010, 2, 3) // Wed, 3 March 2010
 }

The visible range would begin on Sun 28th Feb.

Defaults to:

new Date()

getValue : Date

Returns the value of value

Returns

Date

setValue (value)

Sets the value of value

Parameters

value :  Date

viewModel : String / Object / Ext.app.ViewModel
bindable bind

The ViewModel is a data provider for this component and its children. The data contained in the ViewModel is typically used by adding bind configs to the components that want present or edit this data.

When set, the ViewModel is created and links to any inherited viewModel instance from an ancestor container as the "parent". The ViewModel hierarchy, once established, only supports creation or destruction of children. The parent of a ViewModel cannot be changed on the fly.

If this is a root-level ViewModel, the data model connection is made to this component's associated Ext.data.Session. This is determined by calling getInheritedSession.

Defaults to:

null

getViewModel : String / Object / Ext.app.ViewModel

Returns the value of viewModel

Returns

String / Object / Ext.app.ViewModel

setViewModel (viewModel)

Sets the value of viewModel

Parameters

viewModel :  String / Object / Ext.app.ViewModel

 }

Defaults to:

7

getVisibleDays : Number

Returns the value of visibleDays

Returns

Number

setVisibleDays (visibleDays)

Number[]

setWeekendDays (weekendDays)

Sets the value of weekendDays

Parameters

weekendDays :  Number[]

weight : Number
bindable bind

This value controls this item's order in a weighted Ext.Container (see parent).

Lower values gravitate towards the start of the container - the top in vertical layouts, the locale start side in horizontal layouts.

Defaults to:

0

getWeight : Number

Returns the value of weight

Returns

Number

setWeight (weight)

Sets the value of weight

Parameters

weight :  Number

width : Number / String
bindable bind

The width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. By default, if this is not explicitly set, this Component's element will simply have its own natural size. If set to auto, it will set the width to null meaning it will have its own natural size.

Defaults to:

null

getWidth : Number / String

Returns the value of width

Returns

Number / String

setWidth (width)

Sets the value of width

Parameters

width :  Number / String

x : Number
bindable bind

Only valid when a component is cfg-floated

The x position at which to position this component. This is usually viewport-relative. But if there is a relative: true ancestor, it will be relative to that.

Defaults to:

0

getX : Number

Returns the value of x

Returns

Number

setX (x)

Sets the value of x

Parameters

x :  Number

xtype : String

The xtype configuration option can be used to optimize Component creation and rendering. It serves as a shortcut to the full component name. For example, the component Ext.button.Button has an xtype of button.

You can define your own xtype on a custom Ext.Component by specifying the alias config option with a prefix of widget. For example:

Ext.define('PressMeButton', {
    extend: 'Ext.button.Button',
    alias: 'widget.pressmebutton',
    text: 'Press Me'
});

Any Component can be created implicitly as an object config with an xtype specified, allowing it to be declared and passed into the rendering pipeline without actually being instantiated as an object. Not only is rendering deferred, but the actual creation of the object itself is also deferred, saving memory and resources until they are actually needed. In complex, nested layouts containing many Components, this can make a noticeable improvement in performance.

// Explicit creation of contained Components:
var panel = new Ext.Panel({
   // ...
   items: [
      Ext.create('Ext.button.Button', {
         text: 'OK'
      })
   ]
});

// Implicit creation using xtype:
var panel = new Ext.Panel({
   // ...
   items: [{
      xtype: 'button',
      text: 'OK'
   }]
});

In the first example, the button will always be created immediately during the panel's initialization. With many added Components, this approach could potentially slow the rendering of the page. In the second example, the button will not be created or rendered until the panel is actually displayed in the browser. If the panel is never displayed (for example, if it is a tab that remains hidden) then the button will never be created and will never consume any resources whatsoever.

y : Number
bindable bind

Only valid when a component is cfg-floated

The x position at which to position this component. This is usually viewport-relative. But if there is a relative: true ancestor, it will be relative to that.

Returns

Number

setY (y)

Sets the value of y

Parameters

y :  Number

zIndex : Number
bindable bind

Defaults to:

null

getZIndex : Number

Returns the value of zIndex

Returns

Number

setZIndex (zIndex)

Sets the value of zIndex

Parameters

zIndex :  Number

properties

Instance Properties

$className
private pri

Defaults to:

'Ext.Base'

$configPrefixed : Boolean
private pri

The value true causes config values to be stored on instances using a property name prefixed with an underscore ("_") character. A value of false stores config values as properties using their exact name (no prefix).

Defaults to:

true

Available since: 5.0.0

$configStrict : Boolean
private pri

The value true instructs the initConfig method to only honor values for properties declared in the config block of a class. When false, properties that are not declared in a config block will be placed on the instance.

Defaults to:

true

Available since: 5.0.0

$eventOptions
private pri

Matches options property names within a listeners specification object - property names which are never used as event names.

Defaults to:

{
    scope: 1,
    delay: 1,
    buffer: 1,
    onFrame: 1,
    single: 1,
    args: 1,
    destroyable: 1,
    priority: 1,
    order: 1
}

$vetoClearingPrototypeOnDestroy
private pri

We don't want the base destructor to clear the prototype because our destroyObservable handler must be called the very last. It will take care of the prototype after completing Observable destruction sequence.

Defaults to:

true

activeAnimation
private pri

Defaults to:

null

ariaEl : String
readonly ro private pri

The name of the Component property that holds a reference to the Element that serves as that Component's ARIA element. This property will be replaced with the actual Element reference after rendering.

Most of the simple Components will have their main element as ariaEl.

Defaults to:

'el'

Available since: 6.0.0

ariaRenderAttributes : Object
private pri

Instance specific ARIA attributes to render into Component's ariaEl. This object is only used during rendering, and is discarded afterwards.

ariaRole : String
readonly ro

ARIA role for this Component, defaults to no role. With no role, no other ARIA attributes are set.

baseCls
protected pro

The base CSS class to apply to this widget's element. Used as the prefix for ui-specific class names. Defaults to the value of classCls or (x- + the xtype) of the widget if classCls is null

Defaults to:

null

classCls

A CSS class to apply to the main element that will be inherited down the class hierarchy. Subclasses may override this property on their prototype to add their own CSS class in addition to the CSS classes inherited from ancestor classes via the prototype chain. For example

Ext.define('Foo', {
    extend: 'Ext.Widget',
    classCls: 'foo'
});

Ext.define('Bar', {
    extend: 'Foo',
    classCls: 'bar'
});

var bar = new Bar();

console.log(bar.element.className); // outputs 'foo bar'

Defaults to:

Ext.baseCSSPrefix + 'component'

classClsRoot
protected pro

When set to true during widget class definition, that class will be the "root" for classCls inheritance. Derived classes may set this to true to avoid inheriting a classCls from their superclass.

Defaults to:

true

clearPropertiesOnDestroy : Boolean / "async"
protected pro

Setting this property to false will prevent nulling object references on a Class instance after destruction. Setting this to "async" will delay the clearing for approx 50ms.

Defaults to:

true

Available since: 6.2.0

clearPrototypeOnDestroy : Boolean
private pri

Setting this property to true will result in setting the object's prototype to null after the destruction sequence is fully completed. After that, most attempts at calling methods on the object instance will result in "method not defined" exception. This can be very helpful with tracking down otherwise hard to find bugs like runaway Ajax requests, timed functions not cleared on destruction, etc.

Note that this option can only work in browsers that support Object.setPrototypeOf method, and is only available in debugging mode.

Defaults to:

false

Available since: 6.2.0

containsFocus : Boolean
readonly ro

true if this currently focused element is within this Component's or Container's hierarchy. This property is set separately from hasFocus, and can be true when hasFocus is false.

Examples:

  • Text field with input element focused would be: focusable: true, hasFocus: true, containsFocus: true

  • Date field with drop-down picker currently focused would be: focusable: true, hasFocus: false, containsFocus: true

  • Form Panel with a child input field currently focused would be: focusable: false, hasFocus: false, containsFocus: true

See also hasFocus.

Defaults to:

false

dateInfo : Object
private pri

Contains information about the current date ranges.

Defaults to:

null

defaultBindProperty : String

This property is used to determine the property of a bind config that is just the value. For example, if defaultBindProperty="value", then this shorthand bind config:

 bind: '{name}'

Is equivalent to this object form:

 bind: {
     value: '{name}'
 }

The defaultBindProperty is set to "value" for form fields and to "store" for grids and trees.

Defaults to:

'html'

destroyed : Boolean
protected pro

This property is set to true after the destroy method is called.

Defaults to:

false

dockPositions
readonly ro private pri

Defaults to:

{
    top: true,
    right: true,
    bottom: true,
    left: true
}

element : Object
protected pro

A configuration object for Ext.Element.create() that is used to create the Element template. Subclasses should avoid overriding this property and instead add elements using template.

Supports all the standard options of a Ext.Element.create() config and adds 3 additional options:

  1. reference - this option specifies a name for Element references. These references names become properties of the Widget instance and refer to Ext.Element instances that were created using the template:

      element: {
          reference: 'element',
          children: [{
              reference: 'innerElement'
          }]
      }
    

After construction of a widget the reference elements are accessible as follows:

var foo = new FooWidget(),
    innerEl = foo.innerElement; // an Ext.Element that wraps the innerElement

The reference attribute is optional, but all Widgets must have a 'element' reference on some element within the template (usually the outermost one).

  1. listeners - a standard listeners object as specified by Ext.mixin.Observable.

      element: {
          reference: 'element',
          listeners: {
              click: 'onClick'
          },
          children: [{
              reference: 'innerElement',
              listeners: {
                  click: 'onInnerClick'
              }
          }]
      }
    

Since listeners cannot be attached without an Ext.Element reference the reference property MUST be specified in order to use listeners.

The Widget instance is used as the scope for all listeners specified in this way, so it is invalid to use the scope option in the listeners config since it will always be overwritten using this.

  1. uiCls - a suffix to be appended to the ui-specific CSS class for each ui for this widget. These ui classes are constructed by appending the ui to each classCls or baseCls for the widget. As such, uiCls should never be used on the main element reference, as its uiCls is computed automatically.

For example, assume a widget is defined with a ui of 'alt action' and a uiCls of 'inner-el' on its innerElement reference element:

     Ext.define('Doodad', {
         extend: 'Ext.Widget',
         xtype: 'doodad',

         classCls: 'x-doodad',

         ui: 'alt action',

         element: {
             reference: 'element',

             children: [{
                 reference: 'innerElement',
                 cls: 'x-inner-el',
                 uiCls: 'inner-el'
             }]
         }
     });

This would result in the following markup when rendered:

<div class="x-doodad x-doodad-alt x-doodad-action">
    <div class="x-inner-el x-doodad-inner-el x-doodad-alt-inner-el x-doodad-action-inner-el"></div>
</div>

These additional classes can be used to style the reference element for a particular ui; however, use of uiCls is not typically necessary or recommended. Reference elements should usually be styled using simple descendant selectors:

.x-doodad-alt .x-inner-el {
    color: red;
}

When there is a possibility that widgets can be nested it is best to use direct child selectors to avoid the possibility of selecting all descendants instead of just the reference element for the intended widget:

.x-doodad-alt > .x-inner-el {
    color: red;
}

Only use uiCls when there is a possibility of nesting, AND there may be a variable number of elements between the main element and the reference element in question. For example, Ext.Container with docked items has a different number of elements in between its element and its bodyElement than a Container without docked items because of the wrapping elements that are dynamically added to support docking. To ensure it does not style all descendants it must use a uiCls to style its bodyElement:

.x-container-alt-body-el {
    background: #fff;
}

Note that when uiCls is specified it also adds a class name that does not contain the ui using just the classCls and/or baseCls as the prefix. This class name can be used for base-level styling that does not relate to any particular UI:

.x-container-body-el {
    position: relative;
}

Defaults to:

{
    reference: 'element'
}

eventsSuspended
private pri

Initial suspended call count. Incremented when suspendEvents is called, decremented when resumeEvents is called.

Defaults to:

0

factoryConfig : Object

If this property is specified by the target class of this mixin its properties are used to configure the created Ext.Factory.

floatedSelector : String
readonly ro private pri

The CSS selector to match floated elements.

Defaults to:

".x-floated"

floatingCls : String

The CSS class to add to this component when it is floated at the viewport level.

Defaults to:

Ext.baseCSSPrefix + 'floating'

floatWrapCls : String
readonly ro private pri

The CSS class to add to this component's floatWrap when it's created.

Defaults to:

"x-float-wrap"

focusable : Boolean
readonly ro

true for keyboard interactive Components or Widgets, false otherwise. For Containers, this property reflects interactiveness of the Container itself, not its children. See isFocusable.

Note: It is not enough to set this property to true to make a component keyboard interactive. You also need to make sure that the component's focusEl is reachable via Tab key (tabbable). See also tabIndex.

Defaults to:

false

focusClsEl : Ext.dom.Element

The element that will have the focusCls applied when component's focusEl is focused.

focusEl : Ext.dom.Element

The element that will be focused when focus method is called on this component. Usually this is the same element that receives focus via mouse clicks, taps, and pressing Tab key.

Defaults to:

'el'

hasFocus : Boolean
readonly ro

true if this component's focusEl is focused. See also containsFocus.

Defaults to:

false

hasListeners : Object
readonly ro

This object holds a key for any event that has a listener. The listener may be set directly on the instance, or on its class or a super class (via observe) or on the Ext.app.EventBus. The values of this object are truthy (a non-zero number) and falsy (0 or undefined). They do not represent an exact count of listeners. The value for an event is truthy if the event must be fired and is falsy if there is no need to fire the event.

The intended use of this property is to avoid the expense of fireEvent calls when there are no listeners. This can be particularly helpful when one would otherwise have to call fireEvent hundreds or thousands of times. It is used like this:

 if (this.hasListeners.foo) {
     this.fireEvent('foo', this, arg1);
 }

hideOverflowPopup
private pri

Hide the overflow popup.

Defaults to:

Ext.privateFn

inheritUi : Boolean / String

Set to true on widgets that should inherit ui from their parent container. This property is typically set on the class body, but can be set on an instance as long as it is set prior to the instance being added to its container. This property is inspected at the moment a widget is added to a container, and any UIs on the container are added to the widget at that time. Inherited UIs are in addition to the widget's own ui, and are updated when the container's UI changes.

Defaults to:

false

initFocusable
protected pro

Template method to do any Focusable related initialization that does not involve event listeners creation.

Defaults to:

positioned
private pri

Defaults to:

false

rendered : Boolean
readonly ro

Note that this is a one-way operation. The first time a widget is inserted into the document, this flag is set, and it is never unset.

self : Ext.Class
protected pro

Get the reference to the current class from which this object was instantiated. Unlike Ext.Base#statics, this.self is scope-dependent and it's meant to be used for dynamic inheritance. See Ext.Base#statics for a detailed comparison

Ext.define('My.Cat', {
    statics: {
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
    },

    constructor: function() {
        alert(this.self.speciesName); // dependent on 'this'
    },

    clone: function() {
        return new this.self();
    }
});


Ext.define('My.SnowLeopard', {
    extend: 'My.Cat',
    statics: {

private pri

Adds an element reference to this Widget instance.

Parameters

name :  String

The name of the reference

domNode :  HTMLElement

Returns

:Ext.dom.Element

addElementReferenceOnDemand ( name, domNode )
private pri

Reduces instantiation time for a Widget by lazily instantiating Ext.Element references the first time they are used. This optimization only works for elements with no listeners specified.

Parameters

name :  String

The name of the reference

domNode :  HTMLElement

addListener ( eventName, [fn], [scope], [options], [order] ) : Object
chainable ch

The on method is shorthand for addListener.

Appends an event handler to this object. For example:

myGridPanel.on("itemclick", this.onItemClick, this);

The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

myGridPanel.on({
    cellclick: this.onCellClick,
    select: this.onSelect,
    viewready: this.onViewReady,
    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

myGridPanel.on({
    cellclick: {fn: this.onCellClick, scope: this, single: true},
    viewready: {fn: panel.onViewReady, scope: panel}
});

Names of methods in a specified scope may also be used:

myGridPanel.on({
    cellclick: {fn: 'onCellClick', scope: this, single: true},
    viewready: {fn: 'onViewReady', scope: panel}
});

Parameters

eventName :  String/Object

The name of the event to listen for. May also be an object who's property names are event names.

fn :  Function/String (optional)

The method the event invokes or the name of the method within the specified scope. Will be called with arguments given to Ext.util.Observable#fireEvent plus the options parameter described below.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

options :  Object (optional)

An object containing handler configuration.

Note: The options object will also be passed as the last argument to every event handler.

This object may contain any of the following properties:

scope :  Object

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

delay :  Number

The number of milliseconds to delay the invocation of the handler after the event fires.

single :  Boolean

True to add a handler to handle just the next firing of the event, and then remove itself.

buffer :  Number

Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

onFrame :  Number

Causes the handler to be scheduled to run at the next animation frame event. If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed.

target :  Ext.util.Observable

Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

element :  String

This option is only valid for listeners bound to Ext.Component. The name of a Component property which references an Ext.dom.Element to add a listener to.

This option is useful during Component construction to add DOM event listeners to elements of Ext.Component which will exist only after the Component is rendered.

For example, to add a click listener to a Panel's body:

  var panel = new Ext.panel.Panel({
      title: 'The title',
      listeners: {
          click: this.handlePanelClick,
          element: 'body'
      }
  });

In order to remove listeners attached using the element, you'll need to reference the element itself as seen below.

 panel.body.un(...)

delegate :  String (optional)

A simple selector to filter the event target or look for a descendant of the target.

The "delegate" option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

See the delegate example below.

capture :  Boolean (optional)

When set to true, the listener is fired in the capture phase of the event propagation sequence, instead of the default bubble phase.

The capture option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

stopPropagation :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopPropagation on the event object before firing the handler.

preventDefault :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call preventDefault on the event object before firing the handler.

stopEvent :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopEvent on the event object before firing the handler.

args :  Array (optional)

Optional set of arguments to pass to the handler function before the actual fired event arguments. For example, if args is set to ['foo', 42], the event handler function will be called with an arguments list like this:

 handler('foo', 42, <actual event arguments>...);

destroyable :  Boolean (optional)

When specified as true, the function returns a destroyable object. An object which implements the destroy method which removes all listeners added in this call. This syntax can be a helpful shortcut to using un; particularly when removing multiple listeners. NOTE - not compatible when using the element option. See un for the proper syntax for removing listeners added using the element config.

Defaults to:

false

priority :  Number (optional)

An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.

order :  String (optional)

A legacy option that is provided for backward compatibility. It is recommended to use the priority option instead. Available options are:

  • 'before': equal to a priority of 100
  • 'current': equal to a priority of 0 or default priority
  • 'after': equal to a priority of -100

Defaults to:

'current'

order :  String (optional)

A shortcut for the order event option. Provided for backward compatibility. Please use the priority event option instead.

Defaults to: 'current'

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners =  = myButton.on({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

addManagedListener ( item, ename, [fn], [scope], [options] ) : Object

The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.

Example:

Ext.define('Foo', {
    extend: 'Ext.Component',

    initComponent: function () {
        this.addManagedListener(MyApp.SomeGlobalSharedMenu, 'show', this.doSomething);
        this.callParent();
    }
});

As you can see, when an instance of Foo is destroyed, it ensures that the 'show' listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.

As of version 5.1 it is no longer necessary to use this method in most cases because listeners are automatically managed if the scope object provided to addListener is an Observable instance. However, if the observable instance and scope are not the same object you still need to use mon or addManagedListener if you want the listener to be managed.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item to which to add a listener/listeners.

ename :  Object/String

The event name, or an object containing event name properties.

fn :  Function/String (optional)

If the ename parameter was an event name, this is the handler function or the name of a method on the specified scope.

scope :  Object (optional)

If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

options :  Object (optional)

If the ename parameter was an event name, this is the addListener options.

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners = myButton.mon({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

addPlugin ( plugin )

Adds a plugin. For example:

 list.addPlugin('pullrefresh');

Or:

 list.addPlugin({
     type: 'pullrefresh',
     pullRefreshText: 'Pull to refresh...'
 });

Available since: 6.2.0

Parameters

plugin :  Object/String/Ext.plugin.Abstract

The plugin or config object or alias to add.

afterEdit
private pri

Used to handle joining of a record to a tpl

afterErase
private pri

Used to handle joining of a record to a tpl

afterRender
template tpl

This method is called after the component is initially added to the DOM. If this component Ext.Container other components, the afterRender method for child components is called before the parent's afterRender.

Implementations of this method should avoid reading from the DOM but are free to write to the DOM as needed. To read the DOM, consider implementing onRender instead.

This method is not generally needed because components always have their own DOM element and these are maintained by config property updaters prior to insertion in the DOM. In general, it is always best to manipulate the component's elements outside the DOM where there is no associated reflow or layout cost. This method is useful for situations where the component's elements must be in the DOM in order to be manipulated correctly.

Available since: 6.5.0

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

callOverridden ( args ) : Object
deprecated dep protected pro

Call the original method that was previously overridden with Ext.Base#override

Ext.define('My.Cat', {
    constructor: function() {
        alert("I'm a cat!");
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callOverridden();

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callOverridden(arguments)

Returns

:Object

Returns the result of calling the overridden method

Deprecated since version 4.1.0
Use method-callParent instead.

callParent ( args ) : Object
protected pro

Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override (see Ext#define).

 Ext.define('My.Base', {
     constructor: function (x) {
         this.x = x;
     },

     statics: {
         method: function (x) {
             return x;
         }
     }
 });

 Ext.define('My.Derived', {
     extend: 'My.Base',

     constructor: function () {
         this.callParent([21]);
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // alerts 21

This can be used with an override as follows:

 Ext.define('My.DerivedOverride', {
     override: 'My.Derived',

     constructor: function (x) {
         this.callParent([x*2]); // calls original My.Derived constructor
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // now alerts 42

This also works with static and private methods.

 Ext.define('My.Derived2', {
     extend: 'My.Base',

     // privates: {
     statics: {
         method: function (x) {
             return this.callParent([x*2]); // calls My.Base.method
         }
     }
 });

 alert(My.Base.method(10));     // alerts 10
 alert(My.Derived2.method(10)); // alerts 20

Lastly, it also works with overridden static methods.

 Ext.define('My.Derived2Override', {
     override: 'My.Derived2',

     // privates: {
     statics: {
         method: function (x) {
             return this.callParent([x*2]); // calls My.Derived2.method
         }
     }
 });

 alert(My.Derived2.method(10); // now alerts 40

To override a method and replace it and also call the superclass method, use method-callSuper. This is often done to patch a method to fix a bug.

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callParent(arguments)

Returns

:Object

Returns the result of calling the parent method

callSuper ( args ) : Object
protected pro

This method is used by an override to call the superclass method but bypass any overridden method. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly.

Consider:

 Ext.define('Ext.some.Class', {
     method: function () {
         console.log('Good');
     }
 });

 Ext.define('Ext.some.DerivedClass', {
     extend: 'Ext.some.Class',

     method: function () {
         console.log('Bad');

         // ... logic but with a bug ...

         this.callParent();
     }
 });

To patch the bug in Ext.some.DerivedClass.method, the typical solution is to create an override:

 Ext.define('App.patches.DerivedClass', {
     override: 'Ext.some.DerivedClass',

     method: function () {
         console.log('Fixed');

         // ... logic but with bug fixed ...

         this.callSuper();
     }
 });

The patch method cannot use method-callParent to call the superclass method since that would call the overridden method containing the bug. In other words, the above patch would only produce "Fixed" then "Good" in the console log, whereas, using callParent would produce "Fixed" then "Bad" then "Good".

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callSuper(arguments)

Returns

:Object

Returns the result of calling the superclass method

center Ext.Component
chainable ch

Center this cfg-floated or positioned Component in its parent.

Returns

:Ext.Component

this

createRelayer ( newName, [beginEnd] ) : Function
private pri

Creates an event handling function which re-fires the event from this object as the passed event name.

Parameters

newName :  String

The name under which to re-fire the passed parameters.

beginEnd :  Array (optional)

The caller can specify on which indices to slice.

Returns

:Function

destroy

Destroys the Widget. This method should not be overridden in custom Widgets, because it sets the flags and does final cleanup that must go last. Instead, override doDestroy method to add functionality at destruction time.

destroyMembers ( args )

Destroys member properties by name.

If a property name is the name of a config, the getter is not invoked, so if the config has not been initialized, nothing will be done.

The property will be destroyed, and the corrected name (if the property is a config and config names are prefixed) will set to null in this object's dictionary.

Parameters

args :  String...

One or more names of the properties to destroy and remove from the object.

destroyPlugin ( plugin ) : Ext.plugin.Abstract

Removes and destroys a plugin.

Note: Not all plugins are designed to be removable. Consult the documentation for the specific plugin in question to be sure.

Available since: 6.2.0

Parameters

plugin :  String/Ext.plugin.Abstract

The plugin or its id to remove.

Returns

:Ext.plugin.Abstract

plugin instance or null if not found.

disable

Disables this Component

doAddListener ( name, fn, scope, options, order, caller, manager )
private pri

Parameters

name :  Object

fn :  Object

scope :  Object

options :  Object

order :  Object

caller :  Object

manager :  Object

doDestroy

Perform the actual destruction sequence. This is the method to override in your subclasses to add steps specific to the destruction of custom Component.

If the Component is currently added to a Container it will first be removed from that Container. All Ext.Element references are also deleted and the Component is de-registered from Ext.ComponentManager.

As a rule of thumb, subclasses should destroy their child Components, Elements, and/or other objects before calling parent method. Any object references will be nulled after this method has finished, to prevent the possibility of memory leaks.

Available since: 6.2.0

doFireDelegatedEvent ( eventName, args )
private pri

private pri

Continue to fire event.

Parameters

eventName :  String

args :  Array

enable

Enables this Component

enableBubble ( eventNames )

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. There is no implementation in the Observable base class.

This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component#getBubbleTarget. The default implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly.

Example:

Ext.define('Ext.overrides.form.field.Base', {
    override: 'Ext.form.field.Base',

    //  Add functionality to Field's initComponent to enable the change event to bubble
    initComponent: function () {
        this.callParent();
        this.enableBubble('change');
    }
});

var myForm = Ext.create('Ext.form.Panel', {
    title: 'User Details',
    items: [{
        ...
    }],
    listeners: {
        change: function() {
            // Title goes red if form has been modified.
            myForm.header.setStyle('color', 'red');
        }
    }
});

Parameters

eventNames :  String/String[]

The event name to bubble, or an Array of event names.

findFloatParent ( needsShow )
private pri

The method finds this floated component's floatParent. That means a DOM positioning container which acts as a root element for sibling floated components, and allows allows floated components to be absolutely positioned, and their encapsulating elements to be reordered to produce a visual stacking effect.

This component's element is appended to its floatParent.

There is a global floatParent element, created on demand when the first top level floated component is shown. This may be an item child of a container configured with cfg-floated: true, or a free floated component which is programatically shown.

Child items of components inside a floated component may also be configured floated. These are give a floatParent which is created on demand wrapping the nearest floated ancestor. This means that when that ancestor's element is brought to the top of the stack (by moving its element to the end of its own floatParent), the descendant elements will automatically remain above.

Parameters

needsShow :  Object

findFocusTarget Ext.Component
private pri

Finds an alternate Component to focus if this Component is disabled while focused, or focused while disabled, or otherwise unable to focus.

In both cases, focus must not be lost to document.body, but must move to an intuitively connectible Component, either a sibling, or uncle or nephew.

This is both for the convenience of keyboard users, and also for when focus is tracked within a Component tree such as for ComboBoxes and their dropdowns.

For example, a ComboBox with a PagingToolbar in is BoundList. If the "Next Page" button is hit, the LoadMask shows and focuses, the next page is the last page, so the "Next Page" button is disabled. When the LoadMask hides, it attempt to focus the last focused Component which is the disabled "Next Page" button. In this situation, focus should move to a sibling within the PagingToolbar.

Returns

:Ext.Component

A closely related focusable Component to which focus can move.

findIndex ( sizes, offset ) : Number
private pri

Find the index of a cell via position.

Parameters

sizes :  Number[]

The sizes of each cell in the row/column.

offset :  Number

The offset from the start edge.

Returns

:Number

The index.

findPlugin ( type ) : Ext.plugin.Abstract

Retrieves plugin by its type alias. For example:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: ['listpaging', 'pullrefresh']
 });

 list.findPlugin('pullrefresh').setPullRefreshText('Pull to refresh...');

Note: See also getPlugin.

Available since: 6.2.0

Parameters

type :  String

The Plugin's type as specified by the class's alias configuration.

Returns

:Ext.plugin.Abstract

plugin instance or null if not found.

fireAction ( eventName, args, fn, [scope], [options], [order] )
deprecated dep

Fires the specified event with the passed parameters and executes a function (action). By default, the action function will be executed after any "before" event handlers (as specified using the order option of addListener), but before any other handlers are fired. This gives the "before" handlers an opportunity to cancel the event by returning false, and prevent the action function from being called.

The action can also be configured to run after normal handlers, but before any "after" handlers (as specified using the order event option) by passing 'after' as the order parameter. This configuration gives any event handlers except for "after" handlers the opportunity to cancel the event and prevent the action function from being called.

Parameters

eventName :  String

The name of the event to fire.

args :  Array

Arguments to pass to handlers and to the action function.

fn :  Function

The action function.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

options :  Object (optional)

Event options for the action function. Accepts any of the options of addListener

order :  String (optional)

The order to call the action function relative too the event handlers ('before' or 'after'). Note that this option is simply used to sort the action function relative to the event handlers by "priority". An order of 'before' is equivalent to a priority of 99.5, while an order of 'after' is equivalent to a priority of -99.5. See the priority option of addListener for more details.

Defaults to: 'before'

Deprecated since version 5.5
Use fireEventedAction instead.

fireEvent ( eventName, args ) : Boolean

Fires the specified event with the passed parameters (minus the event name, plus the options object passed to addListener).

An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.

Parameters

eventName :  String

The name of the event to fire.

args :  Object...

Variable number of parameters are passed to handlers.

Returns

:Boolean

returns false if any of the handlers return false otherwise it returns true.

fireEventArgs ( eventName, args ) : Boolean

Fires the specified event with the passed parameter list.

An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.

Parameters

eventName :  String

The name of the event to fire.

args :  Object[]

An array of parameters which are passed to handlers.

Returns

:Boolean

returns false if any of the handlers return false otherwise it returns true.

fireEventedAction ( eventName, args, fn, [scope], [fnArgs] ) : Boolean

Fires the specified event with the passed parameters and executes a function (action). Evented Actions will automatically dispatch a 'before' event passing. This event will be given a special controller that allows for pausing/resuming of the event flow.

By pausing the controller the updater and events will not run until resumed. Pausing, however, will not stop the processing of any other before events.

Parameters

eventName :  String

The name of the event to fire.

args :  Array

Arguments to pass to handlers and to the action function.

fn :  Function/String

The action function.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

fnArgs :  Array/Boolean (optional)

Optional arguments for the action fn. If not given, the normal args will be used to call fn. If false is passed, the args are used but if the first argument is this instance it will be removed from the args passed to the action function.

Parameters

draggable :  Ext.drag.Source

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

initElement
protected pro

Initializes the Element for this Widget instance. If this is the first time a Widget of this type has been instantiated the element config will be processed to create an Element. This Element is then cached on the prototype (see afterCachedConfig) so that future instances can obtain their element by simply cloning the Element that was cached by the first instance.

initElementListeners ( elementConfig )
private pri

Called for the first instance of this Widget to create an object that contains the listener configs for all of the element references keyed by reference name. The object is cached on the prototype and has the following shape:

_elementListeners: {
    element: {
        click: 'onClick',
        scope: this
    },
    fooReference: {
        tap: {
            fn: someFunction,
            delay: 100
        }
    }
}

The returned object is prototype chained to the _elementListeners object of its superclass, and each key in the object is prototype chained to object with the corresponding key in the superclass _elementListeners. This allows element listeners to be inherited and overridden when subclassing widgets.

This method is invoked with the prototype object as the scope

Parameters

elementConfig :  Object

initFocusableElement ( force )
private pri

Sets up the focus listener on this Component's focusEl if it has one.

Form Components which must implicitly participate in tabbing order usually have a naturally focusable element as their focusEl, and it is the DOM event of that receiving focus which drives the Component's onFocus handling, and the DOM event of it being blurred which drives the onBlur handling.

Parameters

force :  Object

initFocusableEvents ( force )
protected pro

Template method to do any event listener initialization for a Focusable. This generally happens after the focusEl is available.

Parameters

force :  Object

initInheritedState ( inheritedState )
protected pro

initUiReference ( referenceName, uiCls, [isInstance] )
private pri

Initializes a "uiReference". Ui rerefences are reference elements that have classCls and ui info in their CSS class names.

Parameters

referenceName :  String

uiCls :  String

isInstance :  Boolean (optional)

pass false if this is not an instance-level reference

skipThis :  Boolean (optional)

Pass true to ignore a viewModel configured on this instance and only consider an inherited view model.

Defaults to: false

Returns

:Ext.app.ViewModel

makeBindableUpdater ( cfg ) : Function
private pri

Returns an update method for the given Config that will call publishState to ensure two-way bindings (via bind) as well as any publishes are updated. This method is cached on the cfg instance for re-use.

Available since: 5.0.0

Parameters

cfg :  Ext.Config

Returns

:Function

The updater function.

mon ( item, ename, [fn], [scope], [options] ) : Object

Shorthand for addManagedListener. The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.

Example:

Ext.define('Foo', {
    extend: 'Ext.Component',

    initComponent: function () {
        this.addManagedListener(MyApp.SomeGlobalSharedMenu, 'show', this.doSomething);
        this.callParent();
    }
});

As you can see, when an instance of Foo is destroyed, it ensures that the 'show' listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.

As of version 5.1 it is no longer necessary to use this method in most cases because listeners are automatically managed if the scope object provided to addListener is an Observable instance. However, if the observable instance and scope are not the same object you still need to use mon or addManagedListener if you want the listener to be managed.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item to which to add a listener/listeners.

ename :  Object/String

The event name, or an object containing event name properties.

fn :  Function/String (optional)

If the ename parameter was an event name, this is the handler function or the name of a method on the specified scope.

scope :  Object (optional)

If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

options :  Object (optional)

If the ename parameter was an event name, this is the addListener options.

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners = myButton.mon({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

moveNext

Move the view forward to view the "next" portion of the view based on the current value. This amount depends on the current view.

movePrevious

Move the view forward to view the "next" portion of the view based on the current value. This amount depends on the current view.

mun ( item, ename, [fn], [scope] )

Shorthand for removeManagedListener. Removes listeners that were added by the mon method.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item from which to remove a listener/listeners.

ename :  Object/String

The event name, or an object containing event name properties.

fn :  Function (optional)

If the ename parameter was an event name, this is the handler function.

scope :  Object (optional)

If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

navigate ( amount, [interval] )

Move the current view by an amount based off of the current value.

Parameters

amount :  Number

The number of intervals to move

interval :  String (optional)

The interval to navigate by. See Ext.Date for valid intervals.

Defaults to: Ext.Date.DAY

on ( eventName, [fn], [scope], [options], [order] ) : Object

The on method is shorthand for addListener.

Appends an event handler to this object. For example:

myGridPanel.on("itemclick", this.onItemClick, this);

The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

myGridPanel.on({
    cellclick: this.onCellClick,
    select: this.onSelect,
    viewready: this.onViewReady,
    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

myGridPanel.on({
    cellclick: {fn: this.onCellClick, scope: this, single: true},
    viewready: {fn: panel.onViewReady, scope: panel}
});

Names of methods in a specified scope may also be used:

myGridPanel.on({
    cellclick: {fn: 'onCellClick', scope: this, single: true},
    viewready: {fn: 'onViewReady', scope: panel}
});

Parameters

eventName :  String/Object

The name of the event to listen for. May also be an object who's property names are event names.

fn :  Function/String (optional)

The method the event invokes or the name of the method within the specified scope. Will be called with arguments given to Ext.util.Observable#fireEvent plus the options parameter described below.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

options :  Object (optional)

An object containing handler configuration.

Note: The options object will also be passed as the last argument to every event handler.

This object may contain any of the following properties:

scope :  Object

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

delay :  Number

The number of milliseconds to delay the invocation of the handler after the event fires.

single :  Boolean

True to add a handler to handle just the next firing of the event, and then remove itself.

buffer :  Number

Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

onFrame :  Number

Causes the handler to be scheduled to run at the next animation frame event. If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed.

target :  Ext.util.Observable

Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

element :  String

This option is only valid for listeners bound to Ext.Component. The name of a Component property which references an Ext.dom.Element to add a listener to.

This option is useful during Component construction to add DOM event listeners to elements of Ext.Component which will exist only after the Component is rendered.

For example, to add a click listener to a Panel's body:

  var panel = new Ext.panel.Panel({
      title: 'The title',
      listeners: {
          click: this.handlePanelClick,
          element: 'body'
      }
  });

In order to remove listeners attached using the element, you'll need to reference the element itself as seen below.

 panel.body.un(...)

delegate :  String (optional)

A simple selector to filter the event target or look for a descendant of the target.

The "delegate" option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

See the delegate example below.

capture :  Boolean (optional)

When set to true, the listener is fired in the capture phase of the event propagation sequence, instead of the default bubble phase.

The capture option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

stopPropagation :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopPropagation on the event object before firing the handler.

preventDefault :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call preventDefault on the event object before firing the handler.

stopEvent :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopEvent on the event object before firing the handler.

args :  Array (optional)

Optional set of arguments to pass to the handler function before the actual fired event arguments. For example, if args is set to ['foo', 42], the event handler function will be called with an arguments list like this:

 handler('foo', 42, <actual event arguments>...);

destroyable :  Boolean (optional)

When specified as true, the function returns a destroyable object. An object which implements the destroy method which removes all listeners added in this call. This syntax can be a helpful shortcut to using un; particularly when removing multiple listeners. NOTE - not compatible when using the element option. See un for the proper syntax for removing listeners added using the element config.

Defaults to:

false

priority :  Number (optional)

An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.

order :  String (optional)

A legacy option that is provided for backward compatibility. It is recommended to use the priority option instead. Available options are:

  • 'before': equal to a priority of 100
  • 'current': equal to a priority of 0 or default priority
  • 'after': equal to a priority of -100

Defaults to:

'current'

order :  String (optional)

A shortcut for the order event option. Provided for backward compatibility. Please use the priority event option instead.

Defaults to: 'current'

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners =  = myButton.on({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

onRender
template tpl

This method is called the first time a component is inserted into the DOM. If this component Ext.Container other components, the onRender method for child components is called after the parent's onRender.

Implementations of this method should avoid modifying the DOM but are free to read from and measure elements as needed. To adjust the DOM, consider implementing afterRender instead.

If this method is overridden, be sure to use callParent to call the base class version.

 onRender: function () {
     this.callParent();

     // custom actions
 }

This method is not generally needed because components always have their own DOM element and these are maintained by config property updaters prior to insertion in the DOM. In general, it is always best to interrogate the component's elements outside the DOM where there is no associated reflow or layout cost. This method is useful for situations where the component's elements must be in the DOM. For example to be measured correctly.
