How to set focus on one of the two JInternalFrame
posted 12 years ago
This is controlled in the DesktopManager... I think the behavior of DefaultDesktopManager is just to set the focus on the first frame it gets from getComponents(). So basically the frame that has been added to the desktop the longest. Unfortunately, the method they call to do this is not part of the API, so you'll have to implement your own DesktopManager to do this in the closeFrame() method.
