“Always on Top” Windows with Java

Try this method of the Window class:

Window.setAlwaysOnTop(boolean)

It works the same way as the default in the Windows TaskManager: switch to another app but it shows always on top.

This was added in Java 1.5

Sample code:

import javax.swing.JFrame;
import javax.swing.JLabel;

public class Annoying {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Hello!!");

        // Set's the window to be "always on top"
        frame.setAlwaysOnTop( true );

        frame.setLocationByPlatform( true );
        frame.add( new JLabel("  Isn't this annoying?") );
        frame.pack();
        frame.setVisible( true );
    }
}

_{Window remains on top even when is not active}
