Minimizing Jinternal Frame without clicking the button

Question

Is there any way to minimize/maximize the JinternalFrame without clicking the minimize/maximize button at the top-right corner of the jinternalframe?

I followed this

Answer 1

The method getAllFrames() "Returns iconified frames as well as expanded frames." On Mac OS X, iconified frames may be ignored. The example below demonstrates the anomaly and employs a List<JInternalFrame> to compensate.

works as I expected, you have to check JInternalFrame#isIconifiable() (eeerght this Veto is really ****)

        getContentPane().add(desktop);
        desktop.add(createInternalFrame(1, Color.RED));
        desktop.add(createInternalFrame(2, Color.GREEN));
