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
