Show JDialog on Windows taskbar

Question

I'm trying to display a JDialog in Windows. How do I show a JDialog (like JFrame) on my Windows taskbar?

A dialog itself cannot have a task bar entry, but you can construct a frame that does not have any visible effect and use it as a parent for the dialog. Then it will look like the dialog has a task bar entry. The following code shows you how to do it:

class MyDialog extends JDialog {      private static final List<Image> ICONS = Arrays.asList(             new ImageIcon("icon_16.png").getImage(),              new ImageIcon("icon_32.png").getImage(),             new ImageIcon("icon_64.png").getImage());      MyDialog() {         super(new DummyFrame("Name on task bar", ICONS));     }      public void setVisible(boolean visible) {         super.setVisible(visible);         if (!visible) {             ((DummyFrame)getParent()).dispose();         }     } }  class DummyFrame extends JFrame {     DummyFrame(String title, List<? extends Image> iconImages) {         super(title);         setUndecorated(true);         setVisible(true);         setLocationRelativeTo(null);         setIconImages(iconImages);     } }
