Ok, I see, you dont want the windows widgets to resize, you want the windows to be able to overlap each other, without changing the size

see Tk::MDI for an example of the kind of work required to make such a widget, it uses Tk::place

Also see "2. Vertical paned window." in the tk demo program "widget", it might contain hints on doing it simpler

I don't know how to get the behavior you want, using geometry managers is mostly trial and error :)

your best might be to use Tk::Canvas

or better still Tk::Zinc / http://web.archive.org/web/20061020033841/http://www.tkzinc.org/ / http://zentara.net/zinc/
