_WRAP_SIGNAL: when the C klass does not have a virtual function

[Debarshi Ray]

When I am using _WRAP_SIGNAL to wrap a signal (eg.,
animation_completed of ChamplainView) it assumes that a virtual method
(eg., klass->animation_completed) is present to allow default signal
handlers. However ChamplainView does not have such a virtual method.
Do I need to fix ChamplainView?

Happy hacking,
Debarshi

You can use the no_default_handler option:

It's probably on purpose.

Thanks. That did the trick for me. Maybe I should have RTFMed a bit
more thoroughly. :-)
