- * @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
- * @cfg {String} arrowTooltip The title attribute of the arrow\r
- * @constructor\r
- * Create a new menu button\r
- * @param {Object} config The config object\r
