Windows taskbar height/width

Question

I can't figure out how to get the windows taskbar height dynamicaly to set my application fullscreen.
As you know, taskbar can be in four positions: bottom, top, left or right, so I'm wondering if it's possible to also know the current position to set the window bounds.

EDIT: Using Lukas link I tryied this:

GraphicsDevice myDevice;
Window myWindow;

try {
    myDevice.setFullScreenWindow(myWindow);
    ...
} finally {
    myDevice.setFullScreenWindow(null);
}

But I'm gettin a NullPointerException

Answer 1

It is possible to obtain the Windows taskbar height if necessary:

Dimension scrnSize = Toolkit.getDefaultToolkit().getScreenSize();
Rectangle winSize = GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds();

int taskBarHeight = scrnSize.height - winSize.height;

Answer 2

You can use:

int taskbarheight = Toolkit.getDefaultToolkit().getScreenSize().height 
    - GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds().height();

or you can use, as well:

JFrame frame = new JFrame();
frame.setSize(GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds().getSize();
