JFrame maximized, display taskbar

[Matti Poro]

How do I set a JFrame maximized so that it won't hide the taskbar?

[Michael Dunn]

either of these don't hide the taskbar for me

frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
(or setExtendedState(MAXIMIZED_BOTH) if extending JFrame)

or

Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
frame.setSize(dim.width,dim.height); (or just setSize(dim.width,dim.height))
(this way ensure there is no setLocation() in your code)

Hmm, both ways hide the taskbar on my Windows XP.

I solved it.

 
JFrame.setDefaultLookAndFeelDecorated(true);
UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName()); 

This makes it to take the whole screen. It doesn't do that if I remove the setDefaultLookAndFeelDecorated(true).
