Yeah, but for some reason when I do getBounds(this) and then re-size the
panel, the drawn graphic can extend beyond the boundaries of the Panel.
Also, zooming is tough because if I simply increase or decrease width
and height, it seems to move the graphic instead of change it's size...
public function zoomIn():void
{
height += 100;
width += 100;
updateDisplayList(unscaledWidth, unscaledHeight);
}
public function zoomOut():void
{
height -= 100;
width -= 100;
updateDisplayList(unscaledWidth, unscaledHeight);
}

You want the bounds of what you drew, so getBounds(this) should
be correct.
If you set scaleX/Y to zoom, you shouldn't need to do anything.
If you set scaleX/Y on an internal thing to zoom or in the case of the
circle, multiply the radius by some zoom factor, then you have to report
that new measuredWidth/Height in measure() and maybe call invalidateList
if you have some property like zoomFactor that we're not already
watching for changes

I thought the container reference was needed by the getBounds()
method - it requires an argument of a UIComponent of some kind, I
thought the custom component would need to know the new size of the
container when it got re-sized. If I don't need the container
reference, then maybe I could just say getBounds(this) instead and it
would work.
Also, I want to implement a method to scale the graphics up and
down, I have that working, but I'm back to the graphic not being
centered and not staying within the boundaries of the Panel container
again when the zoom occurs. I tried calling updateDisplayList again
when the zoom action happens, but that didn't work. Any thoughts there?

I think in the general case, you'll need to set
minHeight/minWidth to zero or something small on the Panel or have fixed
width/height on the Panel to get the Panel to consider putting up
scrollbars.
The graphics object should compute
measuredMinWidth/measuredMinHeight to be the same as
measuredWidht/Height so the Panel will not try to shrink it past its
dimensions.
If you can compute the measurements w/o drawing then you
don't need commitProperties and just draw in updateDisplayList.
I don't know why you need a container reference unless
it is to get the bounds of the container to determine where to draw, but
if you've set up % widht/height you'll be given those dimensions in
updateDisplayList.

Hey Jim, passing minWidth and minHeight to the custom UI
component worked perfectly for me - now the drawn graphic is contained
in the Panel container - thank you!
