Removing JPanel from JFrame

I am currently working on an intro screen for a game developed using JOGL. I want the introduction to be a JPanel with a few buttons to change parameters before starting the game.

So I have a JFrame to which I add a GLCanvas. GLCanvas also contains a GLEventListener. Finally, I add the JPanel.

I have overridden JPanel's paintComponent method to set the background image. I have several buttons inside the panel. Whenever you press the play button, it calls a function that does the following:

frame.remove (JPanel); frame.repaint (); animator.start ();

What happens is that my JPanel goes away correctly, but when repaint is called, my frame is just filled with gray. I know that the animator starts correctly when the display method in my GLEventListener is called.

Does anyone know what the problem is?

What's your LayoutManager? If you didn't specify one, then adding a JPanel will replace the GLCanvas.



I would do your code: frame.remove (JPanel); frame.add (glcanvas); animator.start ();
you may need to insert frame.revalidate (). I don't understand how this all works right now.
