Question

Right now, I have a full screen application which spawns several full screen JFrames based on a configuration file (so I can never predict exactly how many frames I will have). These JFrames are in full-screen mode, like this:

setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
setUndecorated(true);
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
setBounds(0,0,screenSize.width, screenSize.height);

The problem is, these JFrames are misbehaving in a Linux environment. I struggled a whole lot with requestFocus, requestFocusInWindow, toFront, setVisible, etc. But nothing seems to get it to work properly in Linux. The issue lies in the fact that I have several frames and I need to be able to switch between them when I click on a button (it’s basically a menu).

So I’m starting to think a JFrame isn’t the best object to use. Would it be easier to manager multiple frames if they were, say optionPanes? Or something similar? Whatever the solution, I need to be able to DO_NOTHING_ON_CLOSE and setUndecorated (or something similar).

Note: If you don’t see a reason I need to change my JFrame and would know how I can switch focus/view easily, please let me know. This would also be an answer to my problem.

Answer 1

I have decided to use the cardLayout and changing my code around a little bit.
