Answer 1

You should probably create a custom DesktopManager . The DesktopManager is responsible for managing the desktop. In particular you would want to extend the DefaultDesktopManager as it provides the current support for positioning the buttons of the minimized internal frames.

In particular I would think you need to override the getBoundsForIconOf(...) method and probably the getPreviousBounds(...) . You could look at the source code to see how it works for the horizontal layout and modify the code for your vertical layout.

This posting has a little example to get you started: //stackoverflow.com/questions/18433475/jdesktoppane-minimising-jinternalframes. Normally when you maximize an internal frame it will cover any iconified buttons. The custom code will only maximize the internal frame to the top of the iconified buttons.
