Juan, can you please show Gerald a working python example ?

We tried to get some example catalogs into the docs this
past autumn but it didnt make it in... For python, you should
be able to write your python widget in say, mybutton.py, then
you create a Glade catalog like normal, but you say library="python",
and name="mybutton", then any types introduced by the file mybutton.py
will be available, you need to reference them by making <glade-widget-class>
statements and grouping them in the palette with <glade-widget-group>.

Juan, please correct me if I'm wrong on this....

And then... when running python with GtkBuilder, your types must simply be
available before parsing the builder file (I believe thats just a
matter of importing
them first).
