To: comp.lang.java.gui I have a transparent JInternalFrame (background set to Color(0f,0f,0f,0f)) and on this I have a JScrollPane and on this I have a JTree. All items have clear backgrounds. On my JDesktopPane I have a JPEG for the background. What I am after is a way to repaint the JInternalFrame so that when the JInternalFrame is moved, resized, etc., that it automatically (and quickly) repaints the underlying JDesktop image inside the JInternalFrame (maintains illusion of transparency). It is my understanding that a call to JInternalFrame.paintComponents(JInternalFrame.getGraphics()) should repaint all the components contained within the JInternalFrame. However, this simply does not occur. What I get is an initially correct looking JInternalFrame that when I move, the background becomes white. When I use a thread to repaint the JInternalFrame I just get the JTree text overwriting itself. Additionally, I have tried paintAll() and repaint() at the JFrame, JInternalFrame and JInternalFrame.getContentPane() levels...
