Child Window(JDialog) hide when using with fixed screen resolution

[shyam shridhar]

Hello,

I am making my project resolution specific.
It means my project always running in 1024*768 screen resolution whatever is system resolution that does't matter.


But I am facing a critical problem when i running my project and on click any button a new pop up window(JDialog) open when i move slightly move JDialog than JDialog is make invisible after moving mouse over and over JDialog some part of JDialog is visible to me.

I am try setOpaque and many differnet option but my problem is not solve.

check the following code if found any solution then please response me it's urgent :

GraphicsDevice graphicsDevice = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();

GraphicsConfiguration graphConfig = graphicsDevice.getDefaultConfiguration();

DisplayMode displayMode = new DisplayMode(1024, 768, 32,DisplayMode.REFRESH_RATE_UNKNOWN);

JFrame mainframe = new JFrame("",graphConfig);

graphicsDevice.setFullScreenWindow(mainframe);


Thank you very much in advance.

if(graphicsDevice.isDisplayChangeSupported()){
graphicsDevice.setDisplayMode(displayMode);
}
mainFrame.setVisible(true);

for something like this you are far better off posting a sample program
that demonstrates the behavior.

something we can copy/paste/compile/run and see for ourselves

If you are using full screen exclusive mode you can't open any windows/dialogs/etc. From the JavaDocs for GraphicsDevice.setFullScreenMode() -

If isFullScreenSupported returns true, full screen mode is considered to be exclusive, which implies:

* Windows cannot overlap the full-screen window. All other application windows will always appear beneath the full-screen window in the Z-order.

You'll need to "fake" a dialog and paint it in the same frame, but on top of existing components. Painting to the Glass Pane would probably simulate a dialog well.

Hi Nathan,

Thanks for reply.
I actually forget that i submit problem on this forum also.
Now I try to do which you told.Till then you check this Sample Code

sample code:

package window;

import java.awt.Color;
import java.awt.DisplayMode;
import java.awt.GraphicsConfiguration;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;

import javax.swing.JDialog;
import javax.swing.JFrame;

public class Light1 {
JFrame m = null;
JDialog di = null;

public Light1() {

GraphicsDevice graphicsDevice = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
GraphicsConfiguration graphConfig = graphicsDevice.getDefaultConfiguration();

DisplayMode origDisplayMode = graphicsDevice.getDisplayMode();

DisplayMode displayMode = new DisplayMode(1024, 768, 32,origDisplayMode.getRefreshRate());

m = new JFrame("",graphConfig);

m.setBackground(Color.red);
graphicsDevice.setFullScreenWindow(m);

if(graphicsDevice.isDisplayChangeSupported()){
graphicsDevice.setDisplayMode(displayMode);
}
di = new JDialog(m,"");
di.setSize(400,400);
di.setVisible(true);
m.setVisible(true);
}

public static void main(String ar[]) {
Light1 l= new Light1();
}

}

I can't understand meaning of above line. I try to do with GlassPane but i am failed to achived my goal.

a early and good response will be very help full for me.

I modified the above code you posted to give an idea of how I was thinking of using the glasspane to fake a dialog...

It's not great code, but should give you an idea of what to do...

You can press space to display the dialog, press the button on the dialog to close it, and press ESC to exit the app.

package window;
 
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.DisplayMode;
import java.awt.FlowLayout;
import java.awt.GraphicsConfiguration;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
 
import javax.swing.BorderFactory;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.border.BevelBorder;
 
public class Light2 {
JFrame m = null;
JPanel fakeHolder;

private static final Dimension SCREEN_SIZE = new Dimension(640, 480);

private static final Dimension DIALOG_SIZE = new Dimension(200, 150);
 
public Light2() {
 
final GraphicsDevice graphicsDevice = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
GraphicsConfiguration graphConfig = graphicsDevice.getDefaultConfiguration();

DisplayMode origDisplayMode = graphicsDevice.getDisplayMode();

DisplayMode displayMode = new DisplayMode(SCREEN_SIZE.width, SCREEN_SIZE.height , 32,origDisplayMode.getRefreshRate());

m = new JFrame("",graphConfig);

m.getContentPane().setBackground(Color.red);
m.setUndecorated(true);
graphicsDevice.setFullScreenWindow(m);

if(graphicsDevice.isDisplayChangeSupported()){
graphicsDevice.setDisplayMode(displayMode);
}

JPanel fakeDialog = new JPanel();
fakeDialog.setLayout(new BorderLayout());
fakeDialog.setBorder(BorderFactory.createTitledBorder(
BorderFactory.createBevelBorder(BevelBorder.LOWERED),
"FakeDialog"
));
fakeDialog.add(new JLabel("Your message goes here..."), BorderLayout.CENTER);
JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new FlowLayout(FlowLayout.CENTER));
JButton okButton = new JButton("OK");
okButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
fakeHolder.setVisible(false);
}
});
buttonPanel.add(okButton);
fakeDialog.add(buttonPanel, BorderLayout.SOUTH);
fakeDialog.setBounds(
(SCREEN_SIZE.width - DIALOG_SIZE.width) / 2, 
(SCREEN_SIZE.height - DIALOG_SIZE.height) / 2, 
DIALOG_SIZE.width, 
DIALOG_SIZE.height
);
fakeHolder = new JPanel();
fakeHolder.setOpaque(false);
fakeHolder.setLayout(null);
fakeHolder.add(fakeDialog);

m.setGlassPane(fakeHolder);

m.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent evt) {
if (evt.getKeyCode() == KeyEvent.VK_ESCAPE) {
graphicsDevice.setFullScreenWindow(null);
System.exit(0);
}
else if (evt.getKeyCode() == KeyEvent.VK_SPACE) {
fakeHolder.setVisible(true);
}
}
});
}

public static void main(String ar[]) {
Light2 l= new Light2();
}

}
