Re: [gtkmm] Gtk::Container::remove and a question

Ok, ok, thank you very much for your answers :)

Haha, sorry for that, but it's ok now you've explained this to me.
I was thinking differently and as I'm beginning with gtkmm I was asking
myself a lot of newbie questions ;)

Ok, thanks for the code, that's what I'm doing as I know Gtk+. I was
just worried not to be able to use gtkmm only :)

If you want to have a look at our project, here are a few links :
- the homepage (french only for the moment sorry :))
http://perso.wanadoo.fr/kitone/sabrina/site/
- and the gna! webpage with the cvs stuff ...
https://gna.org/projects/sabrina3d/

In fact the original project was written with c++ but was using gtk+.
That was a bit dirty with the callbacks, so we decided to rework it to
use gtkmm (and sigc++) ... and it's actually work in progress.

The custom container was needed because we had troubles with gtkglext
and the gtk_widget_reparent function. We needed a widget like a
Gtk::Paned but allowing us to add more than 2 widgets. I don't know if 
that's always true, but even if it's not needed, that's a good training 
to gtkmm.

The links on the homepage are the old version (the one using gtk+).
The gna! cvs contains the latest gtkmm version but nothing can be done 
with it, we started a week ago to port it to gtkmm.

Thank you and thanks for your work too.
