subwindow in FrameView window

[BramVandenbon]

Dear Java developers,

Does somebody know how to add subwindows (JFrame's) to a FrameView class?

FrameView is a netbeans thingy, which I usually do not even try to use.
But I would like to give it a shot this time.

So basicly what I am looking for is something like ...

FrameView myFrameview = ...;
JFrame myJFrame = ...;
myFrameview.showInside(myJFrame);

So when I maximize the JFrame it should maximize inside the FrameView window. I believe they call this concept MDI (Multiple Document Interface).

Thanks in advance

what's a FrameView??
The only way I know to make an MDI application is using the JDesktopPane as an MDI with JInternalFrame(s) for children.. So the code must look something like

jDesktopPane.add(jInternalFrame, javax.swing.JLayeredPane.DEFAULT_LAYER);
