Full-screen with messageDialog?

Well, now I got this code:

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

public class Main {

public static void main(String[] args) {

// Determine if full-screen mode is supported directly

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();

GraphicsDevice gs = ge.getDefaultScreenDevice();

// Create a window for full-screen mode; add a button to leave full-screen mode

final JFrame frame = new JFrame(gs.getDefaultConfiguration());

JWindow win = new JWindow(frame);

//creating panels

JPanel bottomPanel = new JPanel(new FlowLayout(FlowLayout.RIGHT));

//inserts into bottomPanel

JButton dialogButton = new JButton("Show dialog");

JButton exitButton = new JButton("Exit");

bottomPanel.add(dialogButton);

bottomPanel.add(exitButton);

//inserts panels

win.add(bottomPanel, BorderLayout.SOUTH);

//create a button listener to show a dialog

dialogButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent evt) {

JOptionPane.showMessageDialog(frame, "Error", "Here is an error", JOptionPane.ERROR_MESSAGE);

}

});

// Create a button listener that leaves full-screen mode

exitButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent evt) {

// Return to normal windowed mode

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();

GraphicsDevice gs = ge.getDefaultScreenDevice();

gs.setFullScreenWindow(null);

System.exit(0);

}

});

frame.setVisible(true);

try {

gs.setFullScreenWindow(win);

win.validate();

} catch (Exception ex) {

System.out.println(ex);

}

}

}

But I can't see the Dialog :(

Hope you can help me.

Have you tried to make your windowcomponents painted by the jvm instead of your OS?

(At the beginning of your code)

JFrame.setDefaultLookAndFeelDecorated(true);

JDialog.setDefaultLookAndFeelDecorated(true);

Maybe this could solve some system problem.

Sure :

import java.awt.BorderLayout;

import java.awt.FlowLayout;

import java.awt.GraphicsDevice;

import java.awt.GraphicsEnvironment;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JButton;

import javax.swing.JDialog;

import javax.swing.JFrame;

import javax.swing.JOptionPane;

import javax.swing.JPanel;

public class DialogTest {

public static void main(String[] args) {

JFrame.setDefaultLookAndFeelDecorated(true);

JDialog.setDefaultLookAndFeelDecorated(true);

// Determine if full-screen mode is supported directly

GraphicsEnvironment ge = GraphicsEnvironment

.getLocalGraphicsEnvironment();

GraphicsDevice gs = ge.getDefaultScreenDevice();

// Create a window for full-screen mode; add a button to leave

// full-screen mode

final JFrame frame = new JFrame(gs.getDefaultConfiguration());

// creating panels

JPanel bottomPanel = new JPanel(new FlowLayout(FlowLayout.RIGHT));

// inserts into bottomPanel

JButton dialogButton = new JButton("Show dialog");

JButton exitButton = new JButton("Exit");

bottomPanel.add(dialogButton);

bottomPanel.add(exitButton);

// inserts panels

frame.getContentPane().add(bottomPanel, BorderLayout.SOUTH);

// create a button listener to show a dialog

dialogButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent evt) {

JOptionPane.showMessageDialog(frame, "Error",

"Here is an error", JOptionPane.ERROR_MESSAGE);

}

});

// Create a button listener that leaves full-screen mode

exitButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent evt) {

// Return to normal windowed mode

GraphicsEnvironment ge = GraphicsEnvironment

.getLocalGraphicsEnvironment();

GraphicsDevice gs = ge.getDefaultScreenDevice();

gs.setFullScreenWindow(null);

System.exit(0);

}

});

try {

if (gs.isFullScreenSupported()) {

gs.setFullScreenWindow(frame);

}

} catch (Exception ex) {

System.out.println(ex);

}

frame.setVisible(true);

}

Well, experts can correct me, but it seems to me that the setDefaultLookAndFeelDecorated(false) method allow the OS to paint the corresponding Window, whereas when it is used with a true parameter, the jvm paint the border, the menu and some on.

What makes me conclude this is that when I set it to false, the behaviour of my JFrame is the same as any other WindowXP frame (the resize and move behaviour for example and some others details), and when it is at true the behaviour is very specific to my jvm.

I didn't try this on linux/unix environment, and it is possible that on these OS the jvm always paint Windows by default, so my remarque would not solve the problem. You can try and test the

JFrame.isDefaultLookAndFeelDecorated()

value without modifying it to see.

PS : I've simplified your code, do you really need a window? or a mere JFrame is enough?

Swing has mysteries sometimes...

Have you tried to avoid GraphicsEnvironment, which might raise the problem here, using a setExtendedState(Frame.MAXIMIZED_BOTH); instead :

import java.awt.BorderLayout;

import java.awt.FlowLayout;

import java.awt.Frame;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.JOptionPane;

import javax.swing.JPanel;

public class DialogTest {

public static void main(String[] args) {

// Create a window for full-screen mode; add a button to leave

// full-screen mode

final JFrame frame = new JFrame();//gs.getDefaultConfiguration());

// creating panels

JPanel bottomPanel = new JPanel(new FlowLayout(FlowLayout.RIGHT));

// inserts into bottomPanel

JButton dialogButton = new JButton("Show dialog");

JButton exitButton = new JButton("Exit");

bottomPanel.add(dialogButton);

bottomPanel.add(exitButton);

// inserts panels

frame.getContentPane().add(bottomPanel, BorderLayout.SOUTH);

// create a button listener to show a dialog

dialogButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent evt) {

JOptionPane.showMessageDialog(frame, "Error",

"Here is an error", JOptionPane.ERROR_MESSAGE);

}

});

// Create a button listener that leaves full-screen mode

exitButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent evt) {

System.exit(0);

}

});

frame.setExtendedState(Frame.MAXIMIZED_BOTH);

frame.setVisible(true);

}

}

The last rabbit in my hat. ;-)
