Hey,
We had something similar in our application, only an enabling a button, and
the web version of it was as follows -
protected function creationCompleteHandler(event:FlexEvent):void{
scroller.verticalScrollBar.addEventListener(Event.CHANGE,changeHandler,false,0,true);
scroller.verticalScrollBar.addEventListener(FlexEvent.CHANGE_END,changeHandler,false,0,true);
scroller.verticalScrollBar.addEventListener(FlexEvent.SHOW,changeHandler,false,0,true);
scroller.verticalScrollBar.addEventListener(KeyboardEvent.KEY_UP,changeHandler,false,0,true);
}
public function changeHandler(event:Event=null):void {
agreeButton.enabled = !scroller.verticalScrollBar.visible ||
scroller.verticalScrollBar.value == scroller.verticalScrollBar.maximum;
if(agreeButton.enabled){
scroller.verticalScrollBar.removeEventListener(Event.CHANGE,changeHandler);
scroller.verticalScrollBar.removeEventListener(FlexEvent.CHANGE_END,changeHandler);
scroller.verticalScrollBar.removeEventListener(FlexEvent.SHOW,changeHandler);
scroller.verticalScrollBar.removeEventListener(KeyboardEvent.KEY_UP,changeHandler);
}
}
Good luck,
Evyatar
