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.
