I made a custom component, BitmapButton, which is based on spark.components.Button. It basically just takes three Bitmap objects - upBitmap, overBitmap and downBitmap - and then its skin class, BitmapButtonSkin, uses these bitmaps for each state.

Now the problem: I want to make a ButtonBar which uses my BitmapButton for its buttons. What do you think would be the right way to approach this? Do I need to create a new component such as ToggleBitmapButton and then its skin or can I reuse the classes I’ve already made?
