We are creating software that combines swing and xith3d. The basic window layout is split into two. On the left is a (swing) tree view of some components (left black in the image) and on the right is some toolbars on top and then a tabbed pane where the 3D view is.

How do we make the 3D view resize itself when the user changes the window size? Currently, when the user changes the window size the panel adjusts its size correctly but the 3DCanvas (created with RenderPeer.makeCanvas) stays at fixed size (the resolution specified at creation). So if the window size is grown the 3D view stays in the center and leaves gray empty space around it. We'd like to have the 3D fill the panel at all times. How can we achieve this?
