Problem with setContentPane() in JFrame class
843804Jun 30 2005 — edited Jul 1 2005I recently discovered a problem with the setContentPane method in the JFrame class. When I use setContentPane(Container ..), the previously existing contentPane remains in the stack. I have tried nullifying getContentPane(), and all manner of things, but, each time I use setContentPane, I have another instance of a JPanel in the stack.
I'm using code similar to setContentPane(new CustomJPanel()); and each time the user changes screens, and a similar call to that is made, the old CustomJPanel instance remains in the stack. Can anyone suggest a way around this? On their own the panels do not take up very much memory, but after several hours of usage, they will build up.
