java jdialog taskbar button

Question

hi, i'm traying a jdialog on linux, but it still appears in my taskbar. this is the code? what's wrong?

import javax.swing.JDialog;

public class Main {
    public static void main(String [] args) {
        new mydialog();
    }

    private static class mydialog extends JDialog {
        public mydialog() {
            super();
            setSize(200,200);
            setLocationByPlatform(true);
            setAlwaysOnTop(false);
            setUndecorated(true);
            setVisible(true);
        }
    }
}

Answer 1

try replacing setLocationByPlatform(true); with setLocation(10, 10);

Answer 2

You need to use JWindow if you don't want it to appear in the taskbar.

Answer 3

the only solution I found is to switch from Swing interfaces to gtk interfaces, to do this I used java-gnome. the only problem is that you must change all components of the swing classes to the corresponding gtk classes.
