there wasnt much out there that pointed me in the right direction to
do this. I assumed you just make the new Point based on the object
(in this case a button) and call the localToGlobal function. well,
that aint the way its done! you have to get the container (in this
case a canvas) too and then you take the containers Point and get the
containerToGlobal (the button) from it. Maybe my brain is just fried
and everybody already knows this, but i spent alot of time figuring it
out and the adobe docs didnt help me at all
this function is an example of getting global vars of buttons inside
of a container....
private function getNextProgramGlobal():Point
{
var mainCanvasPoint:Point = new
Point(mainCanvas.x,mainCanvas.y); //get the mainCanvas X and Y
vas to a point
var nextButtonPoint:Point= new Point(nextButton.x,
nextButton.y); //start to convert to global X and Y of the button
//set the mainCanvasPoint to the content of the main canvas (the
//button we are highlighting). this is where i had the problem now
//fixed.
mainCanvasPoint = mainCanvas.contentToGlobal(nextButtonPoint);
return mainCanvasPoint;
}
i hope it helps someone out!!
