[SOLVED] refreshing JFrame's in java

[Despot Despondency]

Hey. I'm having a problem refreshing a JFrame when clearing the contentPane and then adding a new JPanel to it. I've got a JFrame and when I clear the contentPane, with removeAll(), and then add a new JPanel I have to minimize the window and then enlarge it before the changes take affect. Here's the code



package gui;

import javax.swing.JFrame;

public class Interface extends JFrame{

private static final long serialVersionUID = 1L;

private static JFrame frame;

public Interface(){
frame = new JFrame("Risk");
createAndShowGUI();
}

private static void createAndShowGUI(){
FrameUtil.setUp(frame);
frame.setVisible(true);
}

public static void MainMenu(){
frame.getContentPane().removeAll();

MenuPanel menu = new MenuPanel();
frame.setContentPane(menu.getPanel());
}

public static void NewGameMenu(){
frame.getContentPane().removeAll();

NewGamePanel newGamePanel = new NewGamePanel();
frame.setContentPane(newGamePanel.getPanel());
}
}


Any suggestions?

This is off the top of my head, and its a while since I used swing extensively, but I seem to remember there being methods something like revalidate and repaint....those ought to do it.

I might well be remembering the names wrong though..

Actually, this threaed is useful :)

Cool, thanks for your help. Used the validate() function, which seemed to work. Didn't seem to be any mention of it in the threads I found. Cheers again. :)

Just so you know, I believe swing expects you to use revalidate() not validate(). validate is an awt command, so it probably works, but may cause a few quirks, I'd stick to revalidate instead.
