Full Screen window over toolbar

Is it possible to open a full screen window that even covers windows tool bar? If so any simple code examples?

I think that could be an OS issue. It might not let you cover parts of the screen.
Have you tried using the setSize() method?

yeah i can set it to the full height and width using setSize by getting the screen resolution, its just overlapping the toolbar that I cant get. It must be possible, how do some public places have it that their screens are full and you can't see toolbar.

for vista/java 6, this covers the taskbar

Code:

---

JFrame f = new JFrame();
GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().setFullScreenWindow(f);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
