RE: hy;hen/underscore equivalence in signal names?

Thanks for the clarification.  I'm surely not the only one that didn't
know this.

They are interchangeable but wait a second, Owen told me (a few months
ago) on this list that its safer to use hyphens in the case of
property notification
signals; i.e. g_signal_connect (... "notify::my-long-property-name" ...);

I guess there was some bug or technical reason why using underscores in
this case wasn't working. (ofcourse this is in the case of property names
and
not signal names, I just though you ought to know).
