Internal Frame order and canvas Z Index

Hi

Scenario is I am making a java application that has a serious of internal frames and one of them hold a canvas. The internal frames should be able to appear on top of the frame that holds the canvas (a la Photoshop layout). It does this but the frames sit on top of the canvas frame but behind the canvas itself?? I can't find any Z-indexing on the canvas. How do I resolve this problem? I am using Net Beans. Please help :(

cheers for now

Canvas is an AWT, heavy-weight component and will appear on top of all lightweight components ("J"-prefix). Use a JPanel for drawing instead of a Canvas.

Thanks for that. In the end I decided just to use normal frame popups instead of internal frames. But that info will be handy for the future.

Could you explain the difference between heavy and lightweight objects? Is it just the screen order that is effected or anything else?
