16 * @class Ext.SplitButton
18 * A split button that provides a built-in dropdown arrow that can fire an event separately from the default
19 * click event of the button. Typically this would be used to display a dropdown menu that provides additional
20 * options to the primary button action, but any custom handler can provide the arrowclick implementation. Example usage:
22 // display a dropdown menu:
24 renderTo: 'button-ct', // the container id
26 handler: optionsHandler, // handle a click on the button itself
27 menu: new Ext.menu.Menu({
29 // these items will render as dropdown menu items when the arrow is clicked:
30 {text: 'Item 1', handler: item1Handler},
31 {text: 'Item 2', handler: item2Handler}
36 // Instead of showing a menu, you provide any type of custom
37 // functionality you want when the dropdown arrow is clicked:
39 renderTo: 'button-ct',
41 handler: optionsHandler,
42 arrowHandler: myCustomHandler
45 * @cfg {Function} arrowHandler A function called when the arrow button is clicked (can be used instead of click event)
46 * @cfg {String} arrowTooltip The title attribute of the arrow
48 * Create a new menu button
49 * @param {Object} config The config object
52 Ext.SplitButton = Ext.extend(Ext.Button, {
58 initComponent : function(){
59 Ext.SplitButton.superclass.initComponent.call(this);
62 * Fires when this button's arrow is clicked
63 * @param {MenuButton} this
64 * @param {EventObject} e The click event
66 this.addEvents("arrowclick");

71 Ext.SplitButton.superclass.onRender.apply(this, arguments);
72 if(this.arrowTooltip){
73 this.el.child(this.arrowSelector).dom[this.tooltipType] = this.arrowTooltip;
78 * Sets this button's arrow click handler.
79 * @param {Function} handler The function to call when the arrow is clicked
80 * @param {Object} scope (optional) Scope for the function passed above
