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.
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.
Public classes and class members are available for use by any other class or application code and may be relied upon as a stable and persistent within major product versions. Public classes and members may safely be extended via a subclass.
Protected class members are stable public members intended to be used by the
owning class or its subclasses. Protected members may safely be extended via a subclass.
Private classes and class members are used internally by the framework and are not intended to be used by application developers. Private classes and members may change or be omitted from the framework at any time without notice and should not be relied upon in application logic.
static label next to the
method name. *See Static below.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).
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.
item : Object
The config object being added.
The component to be added.
Let's look at each part of the member row:
lookupComponent in this example)( item ) in this example)Ext.Component in this case). This may be omitted for methods that do not
return anything other than undefined or may display as multiple possible values
separated by a forward slash / signifying that what is returned may depend on the
results of the method call (i.e. a method may return a Component if a get method calls is
successful or false if unsuccessful which would be displayed as
Ext.Component/Boolean).PROTECTED in
this example - see the Flags section below)Ext.container.Container in this example). The source
class will be displayed as a blue link if the member originates from the current class
and gray if it is inherited from an ancestor or mixed-in class.view source in the example)item : Object in the example).undefined a "Returns" section
will note the type of class or object returned and a description (Ext.Component in the
example)Available since 3.4.0 - not pictured in
the example) just after the member descriptionDefaults to: false)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.
classInstance.method1().method2().etc();false is returned from
an event handler- 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

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.
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.
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.
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.
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:
Ext.button.Button class has an alternate class name of Ext.Button). Alternate class
names are commonly maintained for backward compatibility.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.
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:
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.
This class encapsulates a collection of DOM elements, providing methods to filter members, or to perform collective actions upon the whole set.
Although they are not listed, this class supports all of the methods of Ext.dom.Element. The methods from these classes will be performed on all the elements in this collection.
All methods return this and can be chained.
Usage:
var els = Ext.select("#some-el div.some-class", true);
// or select directly from an existing element
var el = Ext.get('some-el');
el.select('div.some-class', true);
els.setWidth(100); // all elements become 100 width
els.hide(true); // all elements fade out and hide
// or
els.setWidth(100).hide(true);
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
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
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
}
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
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
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
A reference to the Component that owns this element. This is null if there
is no direct owner.
This property is set to true after the destroy method is called.
Defaults to:
false
Initial suspended call count. Incremented when suspendEvents is called, decremented when resumeEvents is called.
Defaults to:
0
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);
}
true in this class to identify an object as an instantiated CompositeElement, or subclass thereof.
Defaults to:
true
This property is set to true during the call to initConfig.
Defaults to:
false
Available since: 5.0.0
This property is set to true if this instance is the first of its class.
Defaults to:
false
Available since: 5.0.0
This value is true and is used to identify plain objects from instances of
a defined class.
Defaults to:
true
true in this class to identify an object as an instantiated Observable, or subclass thereof.
Defaults to:
true
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: {
speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'
}
});
var cat = new My.Cat(); // alerts 'Cat'
var snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'
var clone = snowLeopard.clone();
alert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'
Defaults to:
Base
Visibility mode constant for use with Ext.dom.Element#setVisibilityMode.
Use CSS clip property to reduce element's dimensions to 0px by 0px, effectively
making it hidden while not being truly invisible. This is useful when an element
needs to be published to the Assistive Technologies such as screen readers.
Defaults to:
4
Visibility mode constant for use with Ext.dom.Element#setVisibilityMode. Use the CSS 'display' property to hide the element.
Defaults to:
2
This property indicates a minimum threshold of vertical resize movement for virtual keyboard detection.
On some mobile browsers the framework needs to keep track of whether window resize events were triggered by the opening or closing of a virtual keyboard so that it can prevent unnecessary re-layout of the viewport. It does this by detecting resize events in the horizontal direction that occur immediately after an editable element is focused or blurred.
Defaults to:
100
Visibility mode constant for use with Ext.dom.Element#setVisibilityMode. Use CSS absolute positioning and top/left offsets to hide the element.
Defaults to:
3
Visibility mode constant for use with Ext.dom.Element#setVisibilityMode.
Use CSS opacity property to reduce element's opacity to 0
Defaults to:
5
True to globally disable the delegated event system. The results of setting this to false are unpredictable since the Gesture publisher relies on delegated events in order to work correctly. Disabling delegated events may cause Gestures to function incorrectly or to stop working completely. Use at your own risk!
Defaults to:
true
The list of valid nodeTypes that are allowed to be wrapped
Defaults to:
{
1: 1,
// ELEMENT_NODE
9: 1
}
Visibility mode constant for use with Ext.dom.Element#setVisibilityMode. Use the CSS 'visibility' property to hide the element.
Note that in this mode, isVisible may return true for an element even though it actually has a parent element that is hidden. For this reason, and in most cases, using the OFFSETS mode is a better choice.
Defaults to:
1
Adds declarative listeners as nested arrays of listener objects.
listeners : Array
true if any listeners were added
Returns the publisher for a given event
eventName : String
noTranslate : Boolean (optional)
true if the event is a non translated event
Adds elements to this Composite object.
els : HTMLElement[]/Ext.dom.CompositeElementLite
Either an Array of DOM elements to add, or another Composite object who's elements should be added.
root : HTMLElement/String (optional)
The root element of the query or id of the root.
This Composite object.
Starts a custom animation on this Element.
The following properties may be specified in from, to, and keyframe objects:
x - The page X position in pixels.y - The page Y position in pixelsleft - The element's CSS left value. Units must be supplied.top - The element's CSS top value. Units must be supplied.width - The element's CSS width value. Units must be supplied.height - The element's CSS height value. Units must be supplied.scrollLeft - The element's scrollLeft value.scrollTop - The element's scrollTop value.opacity - The element's opacity value (between 0 and 1).Be aware that animating an Element which is being used by an Ext Component without in some way informing the Component about the changed element state will result in incorrect Component behaviour. This is because the Component will be using the old state of the element. To avoid this problem, it is now possible to directly animate certain properties of Components.
config : Object
Configuration for Ext.fx.Anim. Note that the to config is required.
The new animation.
Adds the given CSS class(es) to this Element.

This method applies a versioned, deprecation declaration to this class. This
is typically called by the deprecated config.
deprecations : Object
Convenience method for constructing a KeyMap
key : String/Number/Number[]/Object
Either a string with the keys to listen for, the numeric key code, array of key codes or an object with the following options:
fn : Function
The function to call
scope : Object (optional)
The scope (this reference) in which the specified function is executed. Defaults to this Element.
The KeyMap created
Creates a KeyMap for this element
config : Object
The KeyMap config. See Ext.util.KeyMap for more details
The KeyMap created
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}
});
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 -100Defaults 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'
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();
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.
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.
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();
Returns the fractional portion of this element's measurement in the given dimension. (IE9+ only)
dimension : Object
Aligns the element with another element relative to the specified anchor points. If the other element is the document it aligns it to the viewport. The position parameter is optional, and can be specified in any one of the following formats:
t/r/b/l) followed by a percentage along that side. This describes a
point to align with a similar point in the target. So 't0-b0' would be
the same as 'tl-bl', 'l0-r50' would place the top left corner of this item
halfway down the right edge of the target item. This allows more flexibility
and also describes which two edges are considered adjacent when positioning a tip pointer.Following are all of the supported predefined anchor positions:
Value Description
----- -----------------------------
tl The top left corner
t The center of the top edge
tr The top right corner
l The center of the left edge
c The center
r The center of the right edge
bl The bottom left corner
b The center of the bottom edge
br The bottom right corner
You can put a '?' at the end of the alignment string to constrain the positioned element to the Viewport. The element will attempt to align as specified, but the position will be adjusted to constrain to the viewport if necessary. Note that the element being aligned might be swapped to align to a different position than that specified in order to enforce the viewport constraints.
Example Usage:
// align el to other-el using the default positioning
// ("tl-bl", non-constrained)
el.alignTo("other-el");
// align the top left corner of el with the top right corner of other-el
// (constrained to viewport)
el.alignTo("other-el", "tl-tr?");
// align the bottom right corner of el with the center left edge of other-el
el.alignTo("other-el", "br-l?");
// align the center of el with the bottom left corner of other-el and
// adjust the x position by -6 pixels (and the y position by 0)
el.alignTo("other-el", "c-bl", [-6, 0]);
// align the 25% point on the bottom edge of this el
// with the 75% point on the top edge of other-el.
el.alignTo("other-el", 'b25-t75');

this
Tries to blur the element. Any exceptions are caught and ignored.
this
Wraps the specified element with a special 9 element markup/CSS block that renders by default as a gray container with a gradient background, rounded corners and a 4-way shadow.
This special markup is used throughout Ext when box wrapping elements (Ext.button.Button, Ext.panel.Panel when frame=true, Ext.window.Window). The markup is of this form:
<div class="{0}-tl"><div class="{0}-tr"><div class="{0}-tc"></div></div></div>
<div class="{0}-ml"><div class="{0}-mr"><div class="{0}-mc"></div></div></div>
<div class="{0}-bl"><div class="{0}-br"><div class="{0}-bc"></div></div></div>
Example usage:
// Basic box wrap
Ext.get("foo").boxWrap();
// You can also add a custom class and use CSS inheritance rules to customize the box look.
// 'x-box-blue' is a built-in alternative -- look at the related CSS definitions as an example
// for how to create a custom box wrap style.
Ext.get("foo").boxWrap().addCls("x-box-blue");
cls : String (optional)
A base CSS class to apply to the containing wrapper element. Note that there are a number of CSS rules that are dependent on this name to make the overall effect work, so if you supply an alternate base class, make sure you also supply all of the necessary rules.
Defaults to: 'x-box'
The outermost wrapping element of the created box structure.
When an element is moved around in the DOM, or is hidden using display:none, it loses layout, and therefore
all scroll positions of all descendant elements are lost.
This function caches them, and returns a function, which when run will restore the cached positions. In the following example, the Panel is moved from one Container to another which will cause it to lose all scroll positions:
var restoreScroll = myPanel.el.cacheScrollValues();
myOtherContainer.add(myPanel);
restoreScroll();
A function which will restore all descendant elements of this Element to their scroll
positions recorded when this function was executed. Be aware that the returned function is a closure which has
captured the scope of cacheScrollValues, so take care to dereference it as soon as not needed - if is it is a var
it will drop out of scope, and the reference will be freed.
Calculates x,y coordinates specified by the anchor position on the element, adding extraX and extraY values.
anchor : String (optional)
The specified anchor position. See alignTo for details on supported anchor positions.
Defaults to: 'tl'
extraX : Number (optional)
value to be added to the x coordinate
extraY : Number (optional)
value to be added to the y coordinate
size : Object (optional)
An object containing the size to use for calculating anchor position {width: (target width), height: (target height)} (defaults to the element's current size)
[x, y] An array containing the element's x and y coordinates
Calculates the new [x,y] position to move this Positionable into a constrain region.
By default, this Positionable is constrained to be within the container it was added to, or the element it was rendered to.
Priority is given to constraining the top and left within the constraint.
An alternative constraint may be passed.
constrainTo : String/HTMLElement/Ext.dom.Element/Ext.util.Region (optional)
The Element or Ext.util.Region into which this Component is to be constrained. Defaults to the element into which this Positionable was rendered, or this Component's Ext.Component#constrainTo.
proposedPosition : Number[] (optional)
A proposed [X, Y] position to test for validity
and to coerce into constraints instead of using this Positionable's current position.
local : Boolean (optional)
The proposedPosition is local (relative to floatParent if a floating Component)
proposedSize : Number[] (optional)
A proposed [width, height] size to use when calculating
constraints instead of using this Positionable's current size.
If the element needs to be translated, the new [X, Y] position within
constraints if possible, giving priority to keeping the top and left edge in the constrain region.
Otherwise, false.
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"
args : Array/Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callOverridden(arguments)
Returns the result of calling the overridden method
Deprecated since version 4.1.0
Use method-callParent instead.
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.
args : Array/Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callParent(arguments)
Returns the result of calling the parent method
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".
args : Array/Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callSuper(arguments)

el : String/HTMLElement/Ext.dom.Element/Number
The id of an element, or an Ext.Element, or an HtmlElement to find within the composite collection.
This function converts a legacy alignment string such as 't-b' into a pair of edge, offset objects which describe the alignment points of the two regions.
So tl-br becomes {myEdge:'t', offset:0}, {otherEdge:'b', offset:100}
This not only allows more flexibility in the alignment possibilities, but it also resolves any ambiguity as to chich two edges are desired to be adjacent if an anchor pointer is required.
posSpec : Object

This method is called to cleanup an object and its resources. After calling this method, the object should not be used any further in any way, including access to its methods and properties.
To prevent potential memory leaks, all object references will be nulled
at the end of destruction sequence, unless clearPropertiesOnDestroy
is set to false.
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

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');

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.

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)

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

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.
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.

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.

el.getAlignToXY(document, 'c-c');
Returns an object holding as properties this element's CSS classes. The object
can be modified to effect arbitrary class manipulations that won't immediately
go to the DOM. When completed, the DOM node can be updated by calling
setClassMap. The values of the properties should either
be set to truthy values (such as 1 or true) or removed via delete.
var classes = el.getClassMap();

Returns the [X, Y] vector by which this Positionable's element must be translated to make a best
attempt to constrain within the passed constraint. Returns false if the element
does not need to be moved.
Priority is given to constraining the top and left within the constraint.
The constraint may either be an existing element into which the element is to be constrained, or a Ext.util.Region into which this element is to be constrained.

Returns this element's data object. This object holds options that may be
needed by an Ext.fly() call when there is no (cached) Ext.dom.Element
instance tracked.
This method will only return null if this instance has no associated DOM
node. If the DOM node does not have a data object, one will be created. To
avoid this creation, use peekData() instead.

enableToggle: true
});
var btn = Ext.create({
xtype: 'mybutton',
renderTo: Ext.getBody(),
text: 'Test Button'
});
Calling btn.getInitialConfig() would return an object including the config
options passed to the create method:
xtype: 'mybutton',
renderTo: // The document body itself
text: 'Test Button'
Calling btn.getInitialConfig('text')returns 'Test Button'.

Measures and returns the size of this element. When dimension is null (or
not specified), this will be an object with width and height properties.
If dimension is 'w' the value returned will be this element's width. If
dimension is 'h' the returned value will be this element's height.
Unlike getWidth and getHeight this method only returns "precise" (sub-pixel)
sizes based on the getBoundingClientRect API.
Available since: 6.5.0
dimension : 'w'/'h' (optional)
Specifies which dimension is desired. If omitted
then an object with width and height properties is returned.
This element's width, height or both as a readonly
object. This object may be the direct result of getBoundingClientRect and
hence immutable on some browsers.
Measures and returns this element's content. When dimension is null (or

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.
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.
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();
Monitors this Element for the mouse leaving. Calls the function after the specified delay only if the mouse was not moved back into the Element within the delay. If the mouse was moved back in, the function is not called.

...
// Remove mouseleave monitor on menu destroy
this.mouseLeaveMonitor.destroy();

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)

scope : Object (optional)
If the ename parameter was an event name, this is the scope (this reference)
in which the handler function is executed.
Gets the next sibling, skipping text nodes
selector : String (optional)
Find the next sibling that matches the passed simple selector. See Ext.dom.Query for information about simple selectors.
returnDom : Boolean (optional)
true to return a raw dom node instead of an Ext.dom.Element

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}
});
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 -100Defaults 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'
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();

fn : Function/String
The method the event invokes.
scope : Object (optional)
The scope for fn.
options : Object (optional)

All selectors, attribute filters and pseudos below can be combined infinitely
in any order. For example div.foo:nth-child(odd)[@foo=bar].bar:first would be
a perfectly valid selector.
The use of @ and quotes are optional. For example, div[@foo='bar'] is also a valid attribute selector.

this
Relays selected events from the specified Observable as if the events were fired by this.
For example if you are extending Grid, you might decide to forward some events from store. So you can do this inside your initComponent:
this.relayEvents(this.getStore(), ['load']);
The grid instance will then have an observable 'load' event which will be passed the parameters of the store's load event and any function fired with the grid's load event would have access to the grid using the this keyword (unless the event is handled by a controller's control/listen event listener in which case 'this' will be the controller rather than the grid).
origin : Object
The Observable whose events this object is to relay.
events : String[]/Object
Array of event names to relay or an Object with key/value pairs translating to ActualEventName/NewEventName respectively. For example: this.relayEvents(this, {add:'push', remove:'pop'});
Would now redispatch the add event of this as a push event and the remove event as a pop event.
prefix : String (optional)
A common prefix to prepend to the event names. For example:
this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.
A Destroyable object. An object which implements the destroy method which, when destroyed, removes all relayers. For example:
this.storeRelayers = this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
Can be undone by calling
Ext.destroy(this.storeRelayers);
or this.store.relayers.destroy();
Destroys this element by removing it from the cache, removing its DOM reference, and removing all of its event listeners.

Sets the passed attributes as attributes of this element (a style attribute
can be a string, object or function).
Example component (though any Ext.dom.Element would suffice):
var cmp = Ext.create({
xtype: 'component',
html: 'test',
renderTo: Ext.getBody()
});
Once the component is rendered, you can fetch a reference to its outer
element to use set:
cmp.el.set({
foo: 'bar'
});
This sets an attribute on the element of foo="bar":
<div class="x-component x-component-default x-border-box" id="component-1009" foo="bar">test</div>
To remove the attribute pass a value of undefined:
cmp.el.set({
foo: undefined
});
Note:
undefined when the
expandos param is set to false.style results in the request being handed off to
method-applyStyles.cls results in the element's dom's
className property
being set directly. For additional flexibility when setting / removing
classes see:

Animates the transition of any combination of an element's dimensions, xy position and/or opacity. Any of these properties not specified in the config object will not be changed. This effect requires that at least one new dimension, position or opacity setting must be passed in on the config object in order for the function to have any effect. Usage:
// slide the element horizontally to x position 200 while changing the height and opacity
el.shift({ x: 200, height: 50, opacity: .8 });
// common config options shown with default values.
el.shift({

Gets the globally shared flyweight Element, with the passed node as the active element. Do not store a reference to this element - the dom node can be overwritten by other code. Ext#fly is alias for Ext.dom.Element#fly.
Use this to make one-time references to DOM elements which are not going to be accessed again either by application code, or by Ext's classes. If accessing an element which will be processed regularly, then Ext.get will be more appropriate to take advantage of the caching provided by the Ext.dom.Element class.
If this method is called with and id or element that has already been cached by a previous call to Ext.get() it will return the cached Element instead of the flyweight instance.
dom : String/HTMLElement
The DOM node or id.
named : Object
The shared Element object (or null if no matching
element was found).
Returns the top Element that is located at the passed coordinates taking into account the scroll position of the document.
Available since: 6.2.0

y : Number
The y coordinate
asDom : Boolean (optional)
true to return a DOM element.
Defaults to: false
The found element.
Retrieves Ext.dom.Element objects. Ext#get is alias for Ext.dom.Element#get.
This method does not retrieve Ext.Components. This method retrieves Ext.dom.Element objects which encapsulate DOM elements. To retrieve a Component by its ID, use Ext.ComponentManager#get.
When passing an id, it should not include the # character that is used for a css selector.
// For an element with id 'foo'
Ext.get('foo'); // Correct
Ext.get('#foo'); // Incorrect
Uses simple caching to consistently return the same object. Automatically fixes if an object was recreated with the same id via AJAX or DOM.
el : String/HTMLElement/Ext.dom.Element
The id of the node, a DOM Node or an existing Element.
The Element object (or null if no matching element was found).
Returns the active element in the DOM. If the browser supports activeElement on the document, this is returned. If not, the focus is tracked and the active element is maintained internally.
asElement : Boolean

Returns the common ancestor of the two passed elements.
nodeA : Ext.dom.Element/HTMLElement
nodeB : Ext.dom.Element/HTMLElement

className
Retrieves the current orientation of the window. This is calculated by determining if the height is greater than the width.
Orientation of window: 'portrait' or 'landscape'
Retrieves the viewport height of the window.
viewportHeight
Returns the current zoom level of the viewport as a ratio of page pixels to screen pixels.
On touch-screen devices there may be an additional level of zooming that occurs when the user performs a pinch or double-tap to zoom gesture. This is separate from and in addition to the devicePixelRatio. We can detect it by comparing the width of the documentElement to window.innerWidth
forceRead : Object
Retrieves the viewport width of the window.
viewportWidth
Retrieves the viewport size of the window.

Override members of this class. Overridden methods can be invoked via callParent.
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.callParent(arguments);
alert("Meeeeoooowwww");
}
});
var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
// alerts "I'm a cat!"
// alerts "Meeeeoooowwww"
Direct use of this method should be rare. Use Ext.define instead:
Ext.define('My.CatOverride', {
override: 'My.Cat',
constructor: function() {
alert("I'm going to be a cat!");
this.callParent(arguments);
alert("Meeeeoooowwww");
}
});
The above accomplishes the same result but can be managed by the Ext.Loader which can properly order the override and its target class and the build process can determine whether the override is needed based on the required state of the target class (My.Cat).
