Maybe I'm misunderstanding you, but that's what the scaling's all
about. The content is as big as it's going to be, but instead of
scrolling we want it to scale down to fit if larger than its
container, and center if smaller. I kinda wish there was something
like ScrollPolicy.NONEBUTSCALE :)
Or perhaps you're re-stating what Michael said, in which case I
responded by adding measure and updateDisplayList implementations to
the holder, so now the content does get sized (as well as scaled), as
follows.
Thanks.
public class ScaleToFitContentHolder extends UIComponent
{
public var allowInvalidateSize:Boolean = true;
public var content:UIComponent;
public function ScaleToFitContentHolder()
{
}
override protected function measure():void
{
super.measure();
minWidth = measuredWidth =
content.getExplicitOrMeasuredWidth();
minHeight = measuredHeight =
content.getExplicitOrMeasuredHeight();
}
override public function invalidateSize():void
{
if (allowInvalidateSize)
super.invalidateSize();
}
override protected function
updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth, unscaledHeight);
content.setActualSize(unscaledWidth, unscaledHeight);
}
}
