Hello,

I am trying to write a simple Gaim-Plugin. Gaim is a pure Gtk-C
Application and so is the plugin-API. However, I want to write the main
parts of the plugin with C++ using gtkmm. The UI shall be designed with
glade2. I have a simple test.glade file which only contains one widget,
a GtkWindow. Loading the .glade file from within the plugin works fine
using:

- ---
RefPtr<Xml> xml = Xml::create("test.glade");
- ---

The window gets displayed. When I want to access the widget via

- ---	
Gtk::Window* w = 0;
xml->get_widget("window", w);
- ---

I get the following messages from glibmm and libglademm:

- ---
(gaim:23186): glibmm-CRITICAL **:
Glib::ObjectBase*<unnamed>::create_new_wrapper(GObject*): assertion
`wrap_func_table != 0' failed

(gaim:23186): glibmm-WARNING **: failed to wrap type of 'GtkWindow'

(gaim:23186): libglademm-CRITICAL **: widget `window' not found in glade
file `test.glade'
- ---

Could it be that what I want to do is not possible because the gtkmm-API
is not correctly initialized? If so, how could this be achived?

Best regards
Christian
