Extends one class to create a subclass and optionally overrides members with the passed literal. This method * also adds the function "override()" to the subclass that can be used to override members of the class.
* For example, to create a subclass of Ext GridPanel: *
MyGridPanel = Ext.extend(Ext.grid.GridPanel, {
constructor: function(config) {
// Create configuration for this Grid.
var store = new Ext.data.Store({...});
var colModel = new Ext.grid.ColumnModel({...});
// Create a new config object containing our computed properties
// *plus* whatever was in the config parameter.
config = Ext.apply({
store: store,
colModel: colModel
}, config);
MyGridPanel.superclass.constructor.call(this, config);
// Your postprocessing here
},
yourMethod: function() {
// etc.
}
});
*
* This function also supports a 3-argument call in which the subclass's constructor is * passed as an argument. In this form, the parameters are as follows:
*subclass
: Function superclass
: Function overrides
: Object A literal with members which are copied into the subclass's * prototype, and are therefore shared between all instances of the new class.
*This may contain a special member named constructor. This is used * to define the constructor of the new class, and is returned. If this property is * not specified, a constructor is generated and returned which just calls the * superclass's constructor passing on its parameters.
*It is essential that you call the superclass constructor in any provided constructor. See example code.
* @return {Function} The subclass constructor from theoverrides
parameter, or a generated one if not provided.
