Show JFrame when tray icon was clicked even if minimized

I need to restore a hidden window when tray icon is clicked. I've actually already found partial solution:

tray_icon.addMouseListener(new MouseListener() {
  @Override
  public void mouseClicked( MouseEvent e ) {
    //Gui.this refers to my frame
    Gui.this.setVisible(true);
  }
});

This will show the frame if it's behind another window. It will put the frame on top. But if I minimize the frame, it doesn't show the window. It's interesting however, that it slightly highlights the taskbar tab:

Taskbar flashing is nice, but it's not enough:

Note that I plan to allow "minimize to tray" function. This means I'll be even hiding the window completely (provided Java allows it). It still must be possible to show it.

Along with setVisible, there's other thing to be set:

Gui.this.setState(Frame.NORMAL);

When minimized, the frame's state is Frame.ICONIFIED.

This is the complete callback to restore the hidden frame:

   tray_icon.addMouseListener(new MouseListener() {
     @Override
     public void mouseClicked( MouseEvent e ) {
       Gui.this.setVisible(true);
       Gui.this.setState (Frame.NORMAL);
     }
   }

And this is what I use to hide the window and taskbar panel (minimize to tray):

 this.addWindowListener(new WindowAdapter()
 {
    @Override
    public void windowIconified(WindowEvent event) {
      //Hides it from screen
      Gui.this.setState(Frame.ICONIFIED);
      //Hides it from taskbar and screen
      Gui.this.setVisible(false);
    }
 });
