Blend JInternalFrame to its parent JFrame when maxmize it

Hi:

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,
Lily

The two requirements are contradictory. If the JInternalFrame occupies the entire content area of the JFrame, you don't have a "top of right coner of parent JFrame" to place your button.

Not if you're using the SystemLookAndFeel.

Sorry that I did not describe it clearly. The button is on menu bar. The Menu bar still shows in the parent JFrame when the child JInternalFrame is maximized to occupy the content area of JFrame. There are many existing tools like this, for example, Oracle's JDeveloper.

Try this once:
on maximizing the internal frame, setUndecorate it and set the maximum size such that it perfectly fixed in your external fram, do one more thing, when maximizing internal frame set visible the corner buttons already placed in your external frame toolbar with there respetive actions.....

all the best..
