Is it possible to make a window in Java using swing that has a border but not a title bar?

Question

This is the result I'm after:

If it's not possible, that's all I need to hear. If it is possible, I would appreciate an explanation of how to make it happen. I am going to have a menu bar so people can close the window with that.

Answer 1

You can use an undecorated JFrame. Then you just add a Border to the JRootPane of the frame:

JFrame frame = new JFrame(...);
frame.setUndecorated( true );
frame.getRootPane().setBorder( new MatteBorder(4, 4, 4, 4, Color.BLUE) );
