+ * @class Ext.Action\r
+ * <p>An Action is a piece of reusable functionality that can be abstracted out of any particular component so that it\r
+ * can be usefully shared among multiple components. Actions let you share handlers, configuration options and UI\r
+ * updates across any components that support the Action interface (primarily {@link Ext.Toolbar}, {@link Ext.Button}\r
+ * and {@link Ext.menu.Menu} components).</p>\r
+ * <p>Aside from supporting the config object interface, any component that needs to use Actions must also support\r
+ * the following method list, as these will be called as needed by the Action class: setText(string), setIconCls(string),\r
+ * setDisabled(boolean), setVisible(boolean) and setHandler(function).</p>\r
+ * Example usage:<br>\r
+ * <pre><code>\r
+// Define the shared action. Each component below will have the same\r
+// display text and icon, and will display the same message on click.\r
+var action = new Ext.Action({\r
+ {@link #text}: 'Do something',\r
+ {@link #handler}: function(){\r
+ Ext.Msg.alert('Click', 'You did something.');\r
+ },\r
+ {@link #iconCls}: 'do-something',\r
+ {@link #itemId}: 'myAction'\r
+});\r

+ title: 'Actions',\r
+ width: 500,\r
+ height: 300,\r

+ // Add the action directly to a toolbar as a menu button\r
+ action,\r
+ {\r

+ // Add the action to a menu as a text item\r
