+ * @class Ext.SplitButton\r
+ * @extends Ext.Button\r
+ * A split button that provides a built-in dropdown arrow that can fire an event separately from the default\r
+ * click event of the button. Typically this would be used to display a dropdown menu that provides additional\r
+ * options to the primary button action, but any custom handler can provide the arrowclick implementation. Example usage:\r
+ * <pre><code>\r
+// display a dropdown menu:\r
+new Ext.SplitButton({\r
+ renderTo: 'button-ct', // the container id\r
+ text: 'Options',\r
+ handler: optionsHandler, // handle a click on the button itself\r
+ menu: new Ext.menu.Menu({\r
+ items: [\r
+ // these items will render as dropdown menu items when the arrow is clicked:\r
+ {text: 'Item 1', handler: item1Handler},\r
+ {text: 'Item 2', handler: item2Handler}\r
+ ]\r
+ })\r
+});\r
+\r
+// Instead of showing a menu, you provide any type of custom\r
+// functionality you want when the dropdown arrow is clicked:\r
+new Ext.SplitButton({\r
+ renderTo: 'button-ct',\r
+ text: 'Options',\r
+ handler: optionsHandler,\r
+ arrowHandler: myCustomHandler\r
+});\r
+</code></pre>\r
+ * @cfg {Function} arrowHandler A function called when the arrow button is clicked (can be used instead of click event)\r
