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,
