As far as I can tell by looking at gtk/pygtkcellrenderer.c, PyGTK allows
overriding by creating a "stub class" PyGtkGenericCellRenderer that
inherits GtkCellRenderer and overrides its C methods with its own
methods that call into Python. GtkTreeModel is handled exactly the
same.
While this approach works for a specific class, it requires writing
non-trivial glue code for each class that needs to be subclassed. It
doesn't allow a Python programmer to subclass a given GObject class
directly from Python.If that glue code is hand-coded, I guess it's repetitive and can be
generated somehow. In a future pygtk that uses the future introspection
features of GObject, it could probably even be done at runtime for
arbitrary GObjects.
Unfortunately not; the vfunc signatures are only expressed in the header files. Thus they aren't in the binary and aren't accessible to GObject introspection.
