ActionScript 3.0 :: Resize MovieClip Without Scaling Content?

Essentially I'm building an application in Flash, just for the fun of it really. Upon the initial design it was just a static size, now however I've been working on making it completely resizeable (with the original size as the minimum). I've done this on most of the screens correctly. However on the main screen I have several components. All custom built MovieClips basically, and inside these are more MovieClips, and inside those are even more movieclips.

For my question, I'm going to be using a button as my example. I created a button movieclip with a resize function to call after I change the size of it. So it works like this:
ActionScript Code:
buttonMC.width = 200;
buttonMC.height = 150;
buttonMC.resized();

Now this button is inside of another movieclip which is designed to just house a group of similar movieclips. (this structure is not changable; several hundreds of lines are code are specifically designed around it). How to get our button's width from the root timeline, we'd do this:
ActionScript Code:
trace(housingMC.buttonMC.width);

Now, when this frame gets resized, the resizing script changes the width height of the housingMC. Something like this: (not a working example)
ActionScript Code:
//resize listener {
housingMC.width += stageWidth - oldStageWidth; //width difference
housingMC.width += stageHeight - oldStageHeight; //height difference
And the housingMC changes to the correct size in the correct position of the screen.
