I was using comboBox at the time, can't tell you if panel is the same
I'm afraid, but at a guess it probably might be :-)
My source here : http://ifeedme.com/blog/?p=19 (run the demo and right
click), hope it helps.

Cool - do have some sample methods that get the scrollbar width of a
component that extends panel?

Last time I needed the scrollbars property of a component I
found that the scrollbar was protected - so had to extend the component
itself and add methods to get scrollbar width etc.

Right, but I mean I can't seem to find the method or properties
to find the panel's scrollbars in the Panel content area - nothing I
could find in the help docs.
Got it working because I made the dumb mistake of calling width
on the UIComponent instead of the panel itself.

You can access their height and width directly.
How did you get it working?

Hey Eric, I didn't thank you for your help.... thanks.
I have it working now.
By the way, is there a way to get the scrollbar's width
(for the vertical scrollbar) and height style (for the horizontal scroll
bar) in the container form of the panel?

You're probably not taking in account the
panel's border thickness properties. When you get the panel's width
it's including the border (not just where the content is being drawn
like youre imagining). To get the true width of the content area youd
need to subtract getStyle("borderThicknessRight") and
getStyle("borderThicknessLeft").
Hope this helps

So I've been writing an Actionscript component
that extends UIComponent and is wrapped inside a Panel tag. The
UIComponent has code that draws a flowchart of sorts into the content
area of the Panel, based on a dataprovider it's bound to. Everything
works fine there, and the drawn graphics change when the dataprovider
changes automatically. The drawn objects also stay within the
boundaries of the Panel content area, thanks to some help on this list
with overriding some protected methods.
The problem I still have though, is getting the
drawn content to stay centered in the content area, including when the
Panel is resized (either by resizing the browser window, since the
Panel's width is 100%, or by moving an HDividedBox divider that
separates it from other panels), or when the drawn content changes size.
I can measure the size of the drawn content easily enough using the
getBounds() method of Rectangle class, but not the Panel's content area
- the width and height seem to be way off when I measure them.
The other problem is getting the scrollbars to
be accurate. I'm getting really confused by Panel's unscaledWidth,
unscaledHeight, measuredWidth, measuredHeight, width, height,
explicitWidth, and explicitHeight properties and how they all relate to
each other. Is there someone who can explain how the panel's content
area size is calculated and also the scrollbars?
Here is some code snippets from my class:
override protected function
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth,
unscaledHeight);
reposition();
measuredWidth = unscaledWidth;
measuredHeight = unscaledHeight;
}
override protected function measure():void
{
var rect:Rectangle =
getBounds(this);
measuredWidth = rect.width;
measuredHeight = rect.height;
var flowchartRect:Rectangle =
getBounds(_flowchart);
_flowchartWidth =
flowchartRect.width;
_flowchartHeight =
flowchartRect.height;
}
private function reposition(e:Event):void
{
measure();
_flowchart.x = (width/2)-(_flowchart/2);
_flowchart.y = (height/2)-(_flowchart/2);
}
Thanks,
