Actually, I was having some trouble using it with a bound
selectedIndex (and it didn't look as though GoogleMate was doing
that), so I made the following changes. Let me know what you think.
Remove override of createNavItem.
Add:
private var _selectedIndexChanged:Boolean; // Inherited one is
private
override protected function clickHandler(event:MouseEvent):void
{
super.clickHandler(event);
var index:int = getChildIndex(Button(event.currentTarget));
updateSelectionHighlighting(index);
}
private function updateSelectionHighlighting(index:int):void {
// enable all
for (var i:int = 0; i < numChildren; i++)
{
if (getChildAt(i) is LinkButton)
{
enableLink( getChildAt(i) as LinkButton
);
}
}
// disable clicked link
enableLink( getChildAt(index) as LinkButton, false );
}
/**
* enableLink
*/
public function enableLink( link:LinkButton, enable:Boolean=true
):void
{
link.enabled = enable;
link.buttonMode = enable;
link.mouseEnabled = enable;
link.focusEnabled = false;
link.setStyle("textDecoration", (enable ? "underline" : "none")
);
}
override public function set selectedIndex(value:int):void {
_selectedIndexChanged = true;
super.selectedIndex = value;
}
override protected function commitProperties():void
{
super.commitProperties();
if (_selectedIndexChanged) {
_selectedIndexChanged = false;
this.updateSelectionHighlighting(this.selectedIndex);
}
}
