Accessible Buttons

Question

If I have standard button, I use the 'click=dosomething()'
attribute in MXML.
However this doesn't appear to work if you are using the
keyboard to navigate.
What event do you use in this case?

Ok, I knocked up a quick Accessible Button Component which
responds to
pressing the Enter key. It inherits from the Flex Button
Component but just
adds a KeyUp event which then fires a Mouse click on itself.
It's hard wired
to KeyUp but could quite easily be customised to use either
Up or Down.
Use it where you would a normal Flex Button.
<?xml version="1.0" encoding="utf-8"?>
<mx:Button xmlns:mx="

creationComplete="ButtonSetup();">
<mx:Script>
<![CDATA[
public function ButtonSetup():void {
this.addEventListener(KeyboardEvent.KEY_UP,
ButtonReturnPressed );
public function ButtonReturnPressed(evt:KeyboardEvent):void
if(evt.keyCode == Keyboard.ENTER) {
var me:MouseEvent = new MouseEvent( "click" );
dispatchEvent( me );

</mx:Script>
</mx:Button>
