how to keep minimized jinternalframe on top

Question

i have four internal frames and 3 buttons in it .When i hit the maximize button,maximizes but it overlaps all the frames.But my point is that it should show the minimized fr

Answer 1

Here's the result of calling moveToBack() in the maximize button handler. Also remember to call pack() on the internal frame.

Addendum: I've updated the example to include max, min and icon buttons. The buttons use Action for easier testing, and the internal frames have distinct names. See createToolBar() to change the L&F dynamically, e.g.

frame.add(createToolBar(frame), BorderLayout.NORTH);
