Hi all,
I am back after a long time. This time I want to tell you all how I set a window as translucent in java. It was a very cumbersome thing to do before recently. From JDK 6 update 10, java has this facility to set the window as translucent and its very easy.
Recently I did this in one of my projects and wanted to share it with you all.
As of the Java Platform, Standard Edition 6 (Java SE 6) Update 10 release, we can add translucent and shaped windows to our Swing applications.
The translucent and shaped window API was first added to the Java SE 6 Update 10 release as a private API. This functionality was moved to the public AWT package in the JDK 7 release.
Here is an example :
import java.awt.*;
import javax.swing.*;
import static java.awt.GraphicsDevice.WindowTranslucency.*;
public class MyWindow extends JFrame {
public MyWindow() {
super("MyWindow");
setLayout(new GridBagLayout());
setSize(300,200);
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
add(new JButton("Just a Button"));
}
public static void main(String[] args) {
// Determine if the GraphicsDevice supports translucency.
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();
//If translucent windows aren't supported, exit.
if (!gd.isWindowTranslucencySupported(TRANSLUCENT)) {
System.err.println( "Translucency is not supported");
System.exit(0);
}
SwingUtilities.invokeLater(new Runnable() {
public void run() {
MyWindow tw = new MyWindow();
// Set the window to 55% opaque (45% translucent).
tw.setOpacity(0.55f);
// Display the window.
tw.setVisible(true);
}
});
}
}
To learn more please check this link.
Here is how you can select which methods to use according to your JDK version.
