Hi, firstly, many thanks to all who replied, especially Lupus.

I will have a look at this. I must start again and get Gtk+, Gnome,
Glade and libglade up to date and consistent on my system. I don't know 
exactly what libglade does but I'm sure that it will help :-)

Now I'm confused, what is the difference between the scrolled_window
policy and the scrollbar update policies? Glade gives properties for both 
the [hv]scrollbar_policy and [hv]update_policy - sorry to be so dim.

I think that you can get the scrollbars of a scrolled_window in C using
gtk_scrolled_window->hscrollbar (and vscrollbar) but this is not bound.
is there another way to get the scrollbars of a scrolled_window in order
to set_update_policy?

Good question, I thought I had but maybe the widgets were added with
insert_item() in a toolbar or added to a FontSelectionDialog - I'll 
do some research.

Thanks for the attention but please don't spoil your vacation, none of 
this stuff is an emergency for me.

Great news, I didn't fancy all that typing :-).

I'm sorry but I have found one more - $toolbar->set_space_style('empty')

I don't mean to complain, I really love Perl/Gtk and I'm impressed that
it works so well, C and XS is all over my head :-)

Thanks again, regards, Dermot
