Blend JInternalFrame to its parent JFrame when maxmize it
I have a JFrame as parent window and some JInternalFrame as child window. I would like to programe this way: if I click one JInternalFrame's maximize button, this JIntervalFrame will become 'topless' and 'maximized', so that it 'blend' into parent JFrame's contentpane. I will have a button at the top of right coner of parent JFrame, when I click it, it will show child JInternalFrame as minimized so that I can choose which JInternalFrame to work on.
The issue I am trying to deal with is: parent JFrame has Title bar, child JInternalFram has title bar also, when I maxmize the JInternalFrame, I have two title bar at the top screen. Kind of confusing. Another way is to change the color of title bar of JInternalFrame. Is that possible if I am on Windows?
Thanks very much,
