The base CSS class to apply to this component's element. This will also be prepended to other elements within this component. To add specific styling for sub-classes, use the cls config.
Defaults to: Ext.baseCSSPrefix + 'field-input'
Overrides: Ext.Component.baseCls
The border width to use on this Component. Can be specified as a number (in which case all edges get the same border width) or a CSS string like '5 10 10 10'.
Please note that this will not add
a border-color or border-style CSS property to the component; you must do that manually using either CSS or
the style configuration.
Ext.Viewport.add({
centered: true,
width: 100,
height: 100,
border: 3,
style: 'border-color: blue; border-style: solid;'

And your CSS file:
.my-component {
border-color: red;
border-style: solid;
}
The absolute bottom 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 'floating', which means its layout will no
longer be affected by the Container that it resides in.

Defaults to: false
Overrides: Ext.Component.disabled
The CSS class to add to the component when it is disabled
Defaults to: "x-item-disabled"
The dock position of this component in its container. Can be left, top, right or bottom.
Notes
You must use a HTML5 doctype for docked bottom to work. To do this, simply add the following code to the HTML file:
<!doctype html>
So your index.html file should look a little like this:
<!doctype html>
<html>
<head>
<title>MY application title</title>

The height 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.

Optional HTML content to render inside this Component, or a reference to an existing element on the page.
Optional HTML content to render inside this Component, or a reference to an existing element on the page.
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 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.
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.

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 'floating', which means its layout will no
longer be affected by the Container that it resides in.
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.
See the Event guide for more
Note: It is bad practice to specify a listener's config when you are defining a class using Ext.define().
Instead, only specify listeners when you are instantiating your class with Ext.create().
The margin to use on this Component. Can be specified as a number (in which case all edges get the same margin) or a CSS string like '5 10 10 10'
The maximum height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc.

pattern : '[0-9]*'
}
}
});
Even though it extends Ext.field.Text, it will display the number keyboard.
A string value displayed in the input (if supported) when the control is empty.
A string value displayed in the input (if supported) when the control is empty.
An object or array of objects that will provide custom functionality for this component. The only requirement for a valid plugin is that it contain an init method that accepts a reference of type Ext.Component.
When a component is created, if any plugins are available, the component will call the init method on each plugin, passing a reference to itself. Each plugin can then call methods or respond to events on the component as needed to provide its functionality.
For examples of plugins, see Ext.plugin.PullRefresh and Ext.plugin.ListPaging
A plugin by alias:
Ext.create('Ext.dataview.List', {
config: {
plugins: 'listpaging',
itemTpl: '<div class="item">{title}</div>',
store: 'Items'
}
});
Multiple plugins by alias:
Ext.create('Ext.dataview.List', {
config: {
plugins: ['listpaging', 'pullrefresh'],
itemTpl: '<div class="item">{title}</div>',
store: 'Items'
}
});
Single plugin by class name with config options:
Ext.create('Ext.dataview.List', {
config: {
plugins: {
xclass: 'Ext.plugin.ListPaging', // Reference plugin by class
autoPaging: true
},
itemTpl: '<div class="item">{title}</div>',
store: 'Items'
}
});
Multiple plugins by class name with config options:
Ext.create('Ext.dataview.List', {
config: {
plugins: [
{
xclass: 'Ext.plugin.PullRefresh',
pullRefreshText: 'Pull to refresh...'
},
{
xclass: 'Ext.plugin.ListPaging',
autoPaging: true
}
],
itemTpl: '<div class="item">{title}</div>',
store: 'Items'
}
});
true to set the field DOM element readonly attribute to "true". Defaults to undefined, leaving the attribute unset.
A model instance which updates the Component's html based on it's tpl. Similar to the data configuration, but tied to to a record to make allow dynamic updates. This must be a model instance and not a configuration of one.
Optional element to render this Component to. Usually this is not needed because a Component is normally full screen or automatically rendered inside another Container
The absolute right 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 'floating', which means its layout will no
longer be affected by the Container that it resides in.
This configuration has moved to Ext.Container. You can no longer use it in a Ext.Component.

Animation effect to apply when the Component is being shown. Typically you want to use an inbound animation type such as 'fadeIn' or 'slideIn'. For more animations, check the Ext.fx.Animation.type config.
The value that the Field had at the time it was last focused. This is the value that is passed to the Ext.field.Text.change event which is fired if the value has been changed when the Field is blurred.
This will be undefined until the Field has been visited. Compare originalValue.
Defaults to: false
The amount by which the field is incremented or decremented each time the spinner is tapped.
Defaults to undefined, which means that the field goes up or down by 1 each time the spinner is tapped.
true to stop the event that fires when you click outside the floating component.
true to stop the event that fires when you click outside the floating component.
This cfg has been removed since 2.0.0
Optional CSS styles that will be rendered into an inline style attribute when the Component is rendered.
You can pass either a string syntax:
style: 'background:red'
Or by using an object:
style: {
background: 'red'
}
When using the object syntax, you can define CSS Properties by using a string:
style: {
'border-left': '1px solid red'
}
Although the object syntax is much easier to read, we suggest you to use the string syntax for better performance.
The class that is added to the content target when you set styleHtmlContent to true.
Defaults to: "x-html"
true to automatically style the HTML inside the content target of this component (body for panels).
Defaults to: false
The tabIndex for this field.
Note: This only applies to fields that are rendered, not those which are built via applyTo.
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 'floating', which means its layout will no
longer be affected by the Container that it resides in.

Note The data configuration must be set for any content to be shown in the component when using this configuration.
The Ext.(X)Template method to use when updating the content area of the Component. Valid modes are:
Defaults to: 'overwrite'
The type attribute for input fields -- e.g. radio, text, password.
If you want to use a file input, please use the Ext.field.File component instead.
Defaults to: "file"
Overrides: Ext.field.Input.type
true to use a mask on this field, or auto to automatically select when you should use it.
Defaults to: 'auto'
Applies the multiple attribute to the input{boolean}
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.
List of xtypes for Ext.Component. XTypes must not contain periods.
Ext.define('MyApp.CoolPanel', {
extend: 'Ext.panel.Panel',
xtype: 'coolpanel',
config: {
html : 'Yeah!'
}
});
// Using Ext.create
Ext.create('widget.coolpanel');
// Using the shorthand for widgets and in xtypes
Ext.widget('panel', {

Get the reference to the current class from which this object was instantiated. Unlike statics,
this.self is scope-dependent and it's meant to be used for dynamic inheritance. See 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'
Creates new Component.
The standard configuration object.
Overrides: Ext.Evented.constructor, Ext.Component.constructor, Ext.draw.Surface.constructor
Appends an after-event handler.
Same as addListener with order set to 'after'.
The name of the event to listen for.
The method the event invokes.
The scope for fn.
An object containing handler configuration.
Appends a before-event handler. Returning false from the handler will stop the event.
Same as addListener with order set to 'before'.
The name of the event to listen for.
The method the event invokes.
The scope for fn.
An object containing handler configuration.
Adds the specified events to the list of events which this Observable may fire.
This method has been deprecated since 2.0
It's no longer needed to add events before firing.
Appends an event handler to this object. You can review the available handlers by looking at the 'events' section of the documentation for the component you are working with.
Using the options argument, it is possible to combine different types of listeners:
A delayed, one-time listener:
container.addListener('tap', this.handleTap, this, {
single: true,
delay: 100
});
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:
container.addListener({
tap : this.onTap,
swipe: this.onSwipe,
scope: this // Important. Ensure "this" is correct during handler execution
});
One can also specify options for each event handler separately:
container.addListener({
tap : { fn: this.onTap, scope: this, single: true },
swipe: { fn: button.onSwipe, scope: button }
});
See the Events Guide for more.
The name of the event to listen for. May also be an object who's property names are event names.
The method the event invokes. Will be called with arguments given to
fireEvent plus the options parameter described below.
The scope (this reference) in which the handler function is executed. If
omitted, defaults to the object which fired the event.
An object containing handler configuration.
This object may contain any of the following properties:
The scope (this reference) in which the handler function is executed. If omitted, defaults to the object
which fired the event.
The number of milliseconds to delay the invocation of the handler after the event fires.
true to add a handler to handle just the next firing of the event, and then remove itself.
The order of when the listener should be added into the listener queue.
If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.
Available options are before, current and after.
Defaults to: current
Causes the handler to be 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.
Allows you to add a listener onto a element of this component using the elements reference.
Ext.create('Ext.Component', {
listeners: {
element: 'element',
tap: function() {
alert('element tap!');
}
}
});
All components have the element reference, which is the outer most element of the component. Ext.Container also has the
innerElement element which contains all children. In most cases element is adequate.
Uses Ext.ComponentQuery to delegate events to a specified query selector within this item.
// Create a container with a two children; a button and a toolbar
var container = Ext.create('Ext.Container', {
items: [
{
xtype: 'toolbar',
docked: 'top',
title: 'My Toolbar'
},
{
xtype: 'button',
text: 'My Button'
}
]
});
container.addListener({
// Ext.Buttons have an xtype of 'button', so we use that are a selector for our delegate
delegate: 'button',
tap: function() {
alert('Button tapped!');
}
});
The order of when the listener should be added into the listener queue.
Possible values are before, current and after.
Defaults to: 'current'
Adds listeners to any Observable object (or Element) which are automatically removed when this Component is destroyed.
This method has been deprecated since 2.0
All listeners are now automatically managed where necessary. Simply use addListener.
The item to which to add a listener/listeners.
The event name, or an object containing event name properties.
If the eventName parameter was an event name, this is the handler function.
If the eventName parameter was an event name, this is the scope in which
the handler function is executed.
If the eventName parameter was an event name, this is the
addListener options.
Significantly improve instantiation time for Component with multiple references Ext.Element instance of the reference domNode is only created the very first time it's ever used.

Call the original method that was previously overridden with override,
This method is deprecated as callParent does the same thing.
Ext.define('My.Cat', {
constructor: function() {
alert("I'm a cat!");
}
});
My.Cat.override({
constructor: function() {
alert("I'm going to be a cat!");
var instance = this.callOverridden();
alert("Meeeeoooowwww");
return instance;
}
});
var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
// alerts "I'm a cat!"
// alerts "Meeeeoooowwww"
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
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 methods.
Ext.define('My.Derived2', {
extend: 'My.Base',
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',
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 callSuper. This is often done to patch a method to fix a bug.
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', {
method: function () {
console.log('Bad');
// ... logic but with a bug ...
this.callParent();
}
});
To patch the bug in DerivedClass.method, the typical solution is to create an
override:
Ext.define('App.paches.DerivedClass', {
override: 'Ext.some.DerivedClass',
method: function () {
console.log('Fixed');
// ... logic but with bug fixed ...
this.callSuper();
}
});
The patch method cannot use 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".
The arguments, either an array or the arguments object
from the current method, for example: this.callSuper(arguments)
Returns the result of calling the superclass method
Destroys this Component. If it 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
Overrides: Ext.Base.destroy, Ext.Component.destroy
Fires the specified event with the passed parameters and execute a function (action)
at the end if there are no listeners that return false.
The name of the event to fire.
Arguments to pass to handers.
Action.
Scope of fn.
Fires the specified event with the passed parameters (minus the event name, plus the options object passed
to addListener).
The first argument is the name of the event. Every other argument passed will be available when you listen for the event.
Firstly, we set up a listener for our new event.
this.on('myevent', function(arg1, arg2, arg3, arg4, options, e) {
console.log(arg1); // true
console.log(arg2); // 2
console.log(arg3); // { test: 'foo' }
console.log(arg4); // 14
console.log(options); // the options added when adding the listener
console.log(e); // the event object with information about the event
});
And then we can fire off the event.
this.fireEvent('myevent', true, 2, { test: 'foo' }, 14);
An event may be set to bubble up an Observable parent hierarchy by calling enableBubble.
The name of the event to fire.

Overrides: Ext.field.Input.getValue
Returns this Component's xtype hierarchy as a slash-delimited string. For a list of all available xtypes, see the Ext.Component header.
Note: If using your own subclasses, be aware that a Component must register its own xtype to participate in determination of inherited xtypes.
Example usage:
var t = new Ext.field.Text();
alert(t.getXTypes()); // alerts 'component/field/textfield'
The xtype hierarchy string.
Hides this Component optionally using an animation.
You can specify an animation here or a bool to use the hideAnimation config.

Will return false if the field is disabled or has not been rendered yet.
Returns true if this Component is currently disabled.
true if currently disabled.
Tests whether or not this Component is of a specific xtype. This can test whether this Component is descended
from the xtype (default) or whether it is directly of the xtype specified (shallow = true).
If using your own subclasses, be aware that a Component must register its own xtype
to participate in determination of inherited xtypes.
For a list of all available xtypes, see the Ext.Component header.
Example usage:
var t = new Ext.field.Text();
var isText = t.isXType('textfield'); // true
var isBoxSubclass = t.isXType('field'); // true, descended from Ext.field.Field
var isBoxInstance = t.isXType('field', true); // false, not a direct Ext.field.Field instance
The xtype to check for this Component.
false to check whether this Component is descended from the xtype (this is
the default), or true to check whether this Component is directly of the specified xtype.
true if this component descends from the specified xtype, false otherwise.

This object may contain any of the following properties:
The scope (this reference) in which the handler function is executed. If omitted, defaults to the object
which fired the event.
The number of milliseconds to delay the invocation of the handler after the event fires.
true to add a handler to handle just the next firing of the event, and then remove itself.
The order of when the listener should be added into the listener queue.
If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.
Available options are before, current and after.
Defaults to: current
Causes the handler to be 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.
Allows you to add a listener onto a element of this component using the elements reference.
Ext.create('Ext.Component', {
listeners: {
element: 'element',
tap: function() {
alert('element tap!');
}
}
});
All components have the element reference, which is the outer most element of the component. Ext.Container also has the
innerElement element which contains all children. In most cases element is adequate.
Uses Ext.ComponentQuery to delegate events to a specified query selector within this item.
// Create a container with a two children; a button and a toolbar
var container = Ext.create('Ext.Container', {

Shows this component optionally using an animation.
You can specify an animation here or a bool to use the showAnimation config.
Shows this component by another component. If you specify no alignment, it will automatically position this component relative to the reference component.
For example, say we are aligning a Panel next to a Button, the alignment string would look like this:
[panel-vertical (t/b/c)][panel-horizontal (l/r/c)]-[button-vertical (t/b/c)][button-horizontal (l/r/c)]
where t = top, b = bottom, c = center, l = left, r = right.
tl-tr means top-left corner of the Panel to the top-right corner of the Buttontc-bc means top-center of the Panel to the bottom-center of the ButtonYou can put a '?' at the end of the alignment string to constrain the floating element to the Viewport
// show `panel` by `button` using the default positioning (auto fit)
panel.showBy(button);
// align the top left corner of `panel` with the top right corner of `button` (constrained to viewport)
panel.showBy(button, "tl-tr?");
// align the bottom right corner of `panel` with the center left edge of `button` (not constrained by viewport)
panel.showBy(button, "br-cl");
The target component to show this component by.
The specific alignment.
Get the reference to the class from which this object was instantiated. Note that unlike self,
this.statics() is scope-independent and it always returns the class from which it was called, regardless of what
this points to during run-time

totalCreated: 0,
speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
},

// equivalent to: My.Cat.speciesName
alert(this.self.speciesName); // dependent on 'this'
statics.totalCreated++;
},
clone: function() {
var cloned = new this.self(); // dependent on 'this'
cloned.groupName = this.statics().speciesName; // equivalent to: My.Cat.speciesName

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!");
var instance = this.callParent(arguments);
alert("Meeeeoooowwww");
return instance;
}
});
var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
// alerts "I'm a cat!"
// alerts "Meeeeoooowwww"
As of 2.1, direct use of this method is deprecated. Use Ext.define instead:
Ext.define('My.CatOverride', {
override: 'My.Cat',
constructor: function() {
alert("I'm going to be a cat!");
var instance = this.callParent(arguments);
alert("Meeeeoooowwww");
return instance;
}
});
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).
