Yes, of course. But there're some problems with them:
1. not all widgets are available depending on the lib version installed on a system.
2. the creation of a GUI with Glade isn't mostly the problem but getting access to 
   different elements.
3. some widgets can't be created in Glade like Treeviews/lists - only the skeletal 
   structure. The rest is coding by hand
4. GtkBuilder lacks with dynamic layouts e.g. appending/deleting of notebook tabs.
5. the creation of a layout in Gtk is ... very flexible and needs practice ;-)

Yes. I know the problems described in the GtkFixed docu. But it's so damned easy 
to create a GUI with it that I hazard the consequences. And the most people want 
creating a GUI fast and without hours in google and with a long learn curve to 
understand Gtk it's design.

What a pitty :-(

To be honest I don't dare Gtk3-Perl at the moment - I red from time to time here 
on the list about problems with Gtk3 ... So I'll wait a some time before trying it...

Thank you very much for the fast reply :-)

Ok, keep on searching for a solution ... perhaps I find something ... or someone else
has another hint? ...


Best,
Thomas
