Ok, i've got a background image, currently being displayed by a custom canvas class that simply paints the image. I need add some buttons on top of this background image, but how can I do this? The canvas class doesn't allow bottons and the like to added to them, does it? Is there some other component I can extend, set the image as its background, and then add buttons to?

Thanks in advance.
