Re: libglade with Gtk2 and Gnome2

under new-gtk2-perl it shouldn't be much of an issue to get things in
order so that Gtk:GladeXML can be done. i.e. adding GladeXML to the
typemaps, adding the necessary. cflags/libs, etc. i (or muppet) can do
the initial steps toward that in about 5 minutes.i have no experience
with libglade so i wouldn't be the person to do the xs bindings.after
looking at the glade-xml.h header file the complicated part(s) would be
the dealing with functions that involve callbacks.(as is the case with
gtk -> anything mappings) 

short version: can be done, relatively easy to do, someone that knowns
libglade/GladeXML needs to volunteer to do it.

Has anyone written a wrapper for the new libglade?  Gtk::GladeXML is why I fell
in love with the original gtk perl module, but I don't see anything like it in
the new modules.

Dermot Musgrove wrote GladePerl and he has begun writing Glade-Two-Perl. But last release is from last 
september...

Glade-Two-Perl is not the same thing as Gtk::GladeXML.  The former is a
Perl script that builds Perl code from the glade file.  The later is a
Perl Module that takes XML (normally the glade file) and returns a
widget tree.  The biggest difference is that the UI can be changed
without modifying the Perl code with Gtk::GladeXML.  Gtk::GladeXML
doesn't have to build the whole glade file; you can specify a widget to
start building from.  One of my programs allows you to add multiple
copies of a widget tree (an editor + other stuff) to a Gtk::Notebook. 
With Glade-Two-Perl I would have to build that widget tree by hand since
it is dynamically generated, but with Gtk::GladeXML I can create a
placeholder window with the widget tree in it and then call
Gtk::GladeXML->new with the top level widget in that placeholder window.
