Hello! I came up with an idea, hope I’ll be able to do all this ^^

I’m making a game in Java, and since Java 7 I have the following problem:

Whenever I want to pack my JFrame after creating and filling it, it leaves a white “border” on the right and the bottom. The game is 800×600, but Java makes the frames content space a bit wider.

I can workaround this by using a one-time action event with Swings Timer class. But isn’t there a more elegant solution?


private void makeUI() {
ds = new Drawscreen();
window = new JFrame("Goatz! v"+VERSION+" - By AyCe for LD 25");
window.setIconImage(MediaLib.icon);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setResizable(false);
content = window.getContentPane();
content.setPreferredSize(new Dimension(800, 600));
window.pack();
content.add(ds);
window.setLocationRelativeTo(null);
window.setVisible(true);
ds.requestFocusInWindow();
// hackfix for border bug
Timer t = new Timer(1000, new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
window.pack();
}
});
t.setRepeats(false);
t.start();
}


The bug
