For some odd reason you might want to get the width and height of the inside of a Container. You can use the "viewMetrics" property of a container to do it.

			/*-------------------------------------------------------------------
			   Returns a Rectangle object of the inside view area of a Container,
			   instead of the complete width and height.
			 ---------------------------------------------------------------------*/
			private function getViewRectangle(ui:Container):Rectangle
			{
				var e:EdgeMetrics=ui.viewMetrics;
				var r:Rectangle=new Rectangle();
				r.width=ui.width - (e.left + e.right);
				r.height=ui.height - (e.top + e.bottom);
				r.x=e.left;
				r.y=e.top;
				return r;
			}

In the following example I overlay a green box over a Panel to show how it matches the Panel's size.
Comments are welcome.

If everyone got a turn, would you take your turn the same as the others or be different?

I've seen lots of really great knobs, dials, and gauge components. The intended way a person would build their app to use one would most likely be varied . That makes each of these kinds of controls  special because its difficult to make a control that fits a very broad range of functionality/look-n-feel, and probably why I have yet to see "one knob to rule them all".   Sliders, and Buttons are pretty straight forward, but not the "Knob" type of control.

Here is a Flex UI component I've been writing. Click the image to play with what I have made so far.
You can change a variety of properties. The dial and mark are runtime skinnable by setting its "dialBackgroundSkin" or "dialMarkSkin" property to a url with an image. 

Knobs and dials just look cool...I don't know anything about audio editing but I like the site of a sound studio. This is the "Reason" I decided to make a knob component.
