is what I've attempted to follow. However, the methods described here
appear to be obsolete. "import glade" no longer exists. "import
gtk.glade" does not have get_adaptor_for_type.
gobject.new('GladePlaceholder') fails.

What's the right way to do this today? This is on an up-to-date Ubuntu
Maverick box.

? I dont know that it's possible to do with python, I doubt it.

However libgladeui-2 (the new core for Glade 3.10/GTK+ 3.x) will be
coming with gir data, meaning it should not be too hard to generate
python bindings to the Glade core library, which should make this
kind of interaction possible.

Note that until now, python widgets have been implemented in a one-way
fashion, Glade invokes the python interpreter and introspects properties
and the like from python widgets... those python widgets until now dont
have any way to interact with the Glade core.

OK. Thanks for the quick response. I'm quite happy to wait for a
better alternative.

I suppose it would still be possible to implement the Glue for your
python widgets in a C module, might be tricky though (I suppose the
C module would have to act like libgladepython.so and invoke the
interpreter manually as well)... sounds quite tricky but possible.

Yeah, sounds like more trouble than it's worth (for me).
