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