Re : Re : [flexcoders] Re: Problem extending TabNavigator class
I think your scope is incorrect. Try this:
myButton.move(this.width-40, 0);

Re : Re : [flexcoders] Re: Problem extending TabNavigator class
Yes, the code is the following :
override protected function updateDisplayList(w:Number, h:Number):void{
super.updateDisplayList(w,h);
updateButtonPosition();
}
public function updateButtonPosition():void
{
myButton.move(parent.width-40, 0);
}

You should be setting its position every time updateDisplayList( )
is
called. Are you doing that?

The trick is that the TabBar width is null when you call the
createChildren( ) method, so you can't set the position of the button
in this method (which is what I did in the first place). But the
parent width is not null anymore when the updateDisplayList( ) method
is called.
