-/**\r
- * @class Ext.CycleButton\r
- * @extends Ext.SplitButton\r
- * A specialized SplitButton that contains a menu of {@link Ext.menu.CheckItem} elements. The button automatically\r
- * cycles through each menu item on click, raising the button's {@link #change} event (or calling the button's\r
- * {@link #changeHandler} function, if supplied) for the active menu item. Clicking on the arrow section of the\r
- * button displays the dropdown menu just like a normal SplitButton. Example usage:\r
- * <pre><code>\r
-var btn = new Ext.CycleButton({\r
- showText: true,\r
- prependText: 'View as ',\r
- items: [{\r
- text:'text only',\r
- iconCls:'view-text',\r
- checked:true\r
- },{\r
- text:'HTML',\r
- iconCls:'view-html'\r
- }],\r
- changeHandler:function(btn, item){\r
- Ext.Msg.alert('Change View', item.text);\r
- }\r
-});\r
-</code></pre>\r

- * Create a new split button\r
