<span id='Ext-method-define'> /**
|
|
</span> * @method
|
|
* Defines a class or override. A basic class is defined like this:
|
|
*
|
|
* Ext.define('My.awesome.Class', {
|
|
* someProperty: 'something',
|
|
*
|
|
* someMethod: function(s) {
|
|
* alert(s + this.someProperty);
|
|
* }
|
|
*
|
|
* ...
|
|
* });
|
|
*
|
|
* var obj = new My.awesome.Class();
|
|
*
|
|
* obj.someMethod('Say '); // alerts 'Say something'
|
|
*
|
|
* To create an anonymous class, pass `null` for the `className`:
|
|
*
|
|
* Ext.define(null, {
|
|
* constructor: function () {
|
|
* // ...
|
|
* }
|
|
* });
|
|
*
|
|
* In some cases, it is helpful to create a nested scope to contain some private
|
|
* properties. The best way to do this is to pass a function instead of an object
|
|
* as the second parameter. This function will be called to produce the class
|
|
* body:
|
|
*
|
|
* Ext.define('MyApp.foo.Bar', function () {
|
|
* var id = 0;
|
|
*
|
|
* return {
|
|
* nextId: function () {
|
|
* return ++id;
|
|
* }
|
|
* };
|
|
* });
|
|
*
|
|
* When using this form of `Ext.define`, the function is passed a reference to its
|
|
* class. This can be used as an efficient way to access any static properties you
|
|
* may have:
|
|
*
|
|
* Ext.define('MyApp.foo.Bar', function (Bar) {
|
|
* return {
|
|
* statics: {
|
|
* staticMethod: function () {
|
|
* // ...
|
|
* }
|
|
* },
|
|
*
|
|
* method: function () {
|
|
* return Bar.staticMethod();
|
|
* }
|
|
* };
|
|
* });
|
|
*
|
|
* To define an override, include the `override` property. The content of an
|
|
* override is aggregated with the specified class in order to extend or modify
|
|
* that class. This can be as simple as setting default property values or it can
|
|
* extend and/or replace methods. This can also extend the statics of the class.
|
|
*
|
|
* One use for an override is to break a large class into manageable pieces.
|
|
*
|
|
* // File: /src/app/Panel.js
|
|
*
|
|
* Ext.define('My.app.Panel', {
|
|
* extend: 'Ext.panel.Panel',
|
|
*
|
|
* constructor: function (config) {
|
|
* this.callParent(arguments); // calls Ext.panel.Panel's constructor
|
|
* //...
|
|
* },
|
|
*
|
|
* statics: {
|
|
* method: function () {
|
|
* return 'abc';
|
|
* }
|
|
* }
|
|
* });
|
|
*
|
|
* // File: /src/app/PanelPart2.js
|
|
* Ext.define('My.app.PanelPart2', {
|
|
* override: 'My.app.Panel',
|
|
*
|
|
* constructor: function (config) {
|
|
* this.callParent(arguments); // calls My.app.Panel's constructor
|
|
* //...
|
|
* }
|
|
* });
|
|
*
|
|
* Another use of overrides is to provide optional parts of classes that can be
|
|
* independently required. In this case, the class may even be unaware of the
|
|
* override altogether.
|
|
*
|
|
* Ext.define('My.ux.CoolTip', {
|
|
* override: 'Ext.tip.ToolTip',
|
|
*
|
|
* constructor: function (config) {
|
|
* this.callParent(arguments); // calls Ext.tip.ToolTip's constructor
|
|
* //...
