I am trying to create a Perl/Tk app that has a single main container under which multiple subwindows can be created via menus by the user. The desired behaviors are that the user should be able to move, resize, iconify, and deiconify each subwindow, but only within the bounds of the outer window. The end goal is much like many MS Windows apps where you can open a number of documents and arrange them all in the main window however you want.

It seems like I want to "embed" numerous Toplevels in either a canvas, or frame which will be under the MainWindow. I have tried that and the problem is that the window-ness of the Toplevel goes away when I used "-use" and "-container" to get that to happen. The canvas widget doesn't want me to createWindow for a toplevel either. I have searched the web and looked at tutorials. Any suggestions?
