|
</span> * 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. Example usage:
|
*
|
* @example
|
* // display a dropdown menu:
|
* Ext.create('Ext.button.Split', {
|
* renderTo: Ext.getBody(),
|
* text: 'Options',
|
* // handle a click on the button itself
|
* handler: function() {
|
* alert("The button was clicked");
|
* },
|
* menu: new Ext.menu.Menu({
|
* items: [
|
* // these will render as dropdown menu items when the arrow is clicked:
|
* {text: 'Item 1', handler: function(){ alert("Item 1 clicked"); }},
|
* {text: 'Item 2', handler: function(){ alert("Item 2 clicked"); }}
|
* ]
|
* })
|
* });
|
*
|
* Instead of showing a menu, you can 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
|
* });
|
