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. Example usage: + *
+// display a dropdown menu:
+new Ext.SplitButton({
+ 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:
+new Ext.SplitButton({
+ renderTo: 'button-ct',
+ text: 'Options',
+ handler: optionsHandler,
+ arrowHandler: myCustomHandler
+});
+
+ * @cfg {Function} arrowHandler A function called when the arrow button is clicked (can be used instead of click event)
