You can create a global PAINT listener to detect screen resize.

// screen resize listener
    Toolkit.getDefaultToolkit().addAWTEventListener(new AWTEventListener() {

        @Override
        public void eventDispatched(AWTEvent event) {
// take a look at http://stackoverflow.com/questions/10123735/get-effective-screen-size-from-java
            Rectangle newSize = getEffectiveScreenSize(); 
            if (newSize.width != windowSize.width || newSize.height != windowSize.height)
                resize();

        }
    }, AWTEvent.PAINT_EVENT_MASK);
