multiple mainwindows

[jpn]

I assume it's also possible to have a main QMainWindow class which has other QMainWindow members?

Yes, you can use QMainWindow like any other QWidget. You could create for example nested dock areas by placing a QMainWindow inside QDockWidget but of course it might not be very intuitive to the end-user.

Well I was thinking about a modal editor with a mainmenu but later I realized I haven't seen such a thing ever.
