        w.setLocation(parent.getX() + (parentSize.width - w.getWidth()) / 2,
                parent.getY() + (parentSize.height - w.getHeight()) / 2);
    }
}

From source file:GUIUtils.java

/**

 * center within the screen. If centering would cause the title bar to go
 * above the parent (I.E. cannot see the titlebar and so cannot move the

 * 
 * @param wind
 *          The Window to be centered.
 * 
 * @throws IllegalArgumentException
 *           If <TT>wind</TT> is <TT>null</TT>.
