I have a JFrame consisting of two panels (Panel#1 is a gridlayout(2,2) and Panel#2 is a BorderLayout)...both panels are placed within the Content Pane along with a menubar...so, Panel# is placed in the CENTER and Panel#2 is place in the SOUTH...I want to add JInternalFrames that get launched when a particular menu item is selected...I'm not using a DesktopPane cuz where would it go...so, which pane does the JInternalFrames get added? Do I have to add a Glass Pane and overlay that on top of the Content Pane?
