GtkOptionMenu, GtkComboBox

[Luke Moloney <lmoloney pandorabenevolentsociety org>]

Hey all.  I'm trying to implement a drop-down box which is dynamically 
populated.  I initially wanted to use a GtkOptionMenu, but noted that 
this is a deprecated widget.  I can create a GtkComboBox in glade and 
get "changed" signals, but I can't change the contents.

When running my program, I get the following message:

GType 'GtkComboBox' is not registered with GPerl; representing this 
object as first known parent type 'GtkBin' instead at 
/Library/Perl/5.8.1/darwin-thread-multi-2level/Gtk2/GladeXML.pm line 
96.

Yet, it pops up and I can get "changed" messages.  I can't seem to do 
anything with this widget, however.  For example, if I call:

$menuWidget->get_active();

I get:

Can't locate object method "get_active" via package "Gtk2::Bin" at 
ogcalc.pm line 104.

So what's going on here?  I assume this means that there are some perl 
bindings missing from gtk2-perlxml or something?  How can I add this 
functionality?  Am I using the wrong widget or something?  Here are my 
versions:

OS - Mac OS-X 10.3
fink 0.23.8
Gtk2 (installed via fink) - 1.021-22
Glade (installed via fink) - 2.6.8-2
gtk2-gladexml (via tarball) - 1.005
