I've got another issue now.
The mouse pointer change only takes effect *after* the rest of my code ( 
that the user is waiting for, hence the hourglass ) has finished.

I assume this has something do with with gtk only doing updates in 
'idle' cycles. I found the following post in the archives that talks 
about something like this:
http://mail.gnome.org/archives/gtk-perl-list/2004-April/msg00021.html

So, can I do something like this?

# turn on hourglass
$mywindow->window->set_cursor(Gtk2::Gdk::Cursor->new("watch"));

Glib::Timeout->add (20, sub {
  
   # do some stuff
   do_stuff();
  
   # turn off hourglass
   $mywindow->window->set_cursor(Gtk2::Gdk::Cursor->new("left-ptr"));
   return 0
  
}

Can I be assured that the code will only run once, or can it be 
triggered again before the 1st run is completed?
