Using two screens in Win XP 2

[allanhn]

I'm running Windows XP with two screens attached.

I need to show two different images - one on each screen.

How do I tell my Java application to show an image on a specific screen??

Haven't checked if this does address your question.. but looks like it does

The following code is taken from the book "Core JFC" by Kim Topley. It prints out information about your monitors and puts a frame with an image on all of the monitors. The monitors don't need to display the same nr of colors or to be set to the same resolution :

package com.ecc.swing2;

import java.awt.*;
import javax.swing.*;

public class MultimonitorExample {

public static void main(String[] args) {
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gd = ge.getScreenDevices();
System.out.println("There are " + gd.length + " screen device(s)"
ImageIcon image = new ImageIcon("D:/images/Belgium.gif"
for (int i = 0; i < gd.length; i++) {
GraphicsConfiguration[] gcs = gd.getConfigurations();
System.out.println(&quot;Device &quot; + i + &quot; has &quot; + gcs.length + &quot; configuration(s)&quot;
for (int j=0; j<gcs.length; j++) {
System.out.println(&quot;\tConfig &quot; + j + &quot; bounds: &quot; + gcs[j].getBounds());
}
JFrame f = new JFrame(&quot;Screen &quot; + i);
JLabel l = new JLabel(image);
f.getContentPane().add(l);
f.pack();
GraphicsConfiguration gc = gd.getDefaultConfiguration();
Rectangle pt = gc.getBounds();
f.setLocation(pt.x + 100, pt.y +100);
f.setVisible(true);
}
}

}

Correction : The code put between &quot;code&quot; and &quot;/code&quot;

package com.ecc.swing2;

import java.awt.*;
import javax.swing.*;

public class MultimonitorExample {

  public static void main(String[] args) {
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice[] gd = ge.getScreenDevices();
    System.out.println("There are " + gd.length + " screen device(s)");
    ImageIcon image = new ImageIcon("D:/images/Belgium.gif");
    for (int i = 0; i < gd.length; i++) {
      GraphicsConfiguration[] gcs = gd[i].getConfigurations();
      System.out.println(&quot;Device &quot; + i + &quot; has &quot; + gcs.length + &quot; configuration(s)&quot;);
      for (int j=0; j<gcs.length; j++) {
        System.out.println(&quot;\tConfig &quot; + j + &quot; bounds: &quot; + gcs[j].getBounds());
      }
    JFrame f = new JFrame(&quot;Screen &quot; + i);
    JLabel l = new JLabel(image);
    f.getContentPane().add(l);
    f.pack();
    GraphicsConfiguration gc = gd[i].getDefaultConfiguration();
    Rectangle pt = gc.getBounds();
    f.setLocation(pt.x + 100, pt.y +100);
    f.setVisible(true);
    }
  }

}
