Re: [gtkmm] Connecting signals to class methods

[Ainsley Pereira <gtkmm pebble org uk>]

Really this question would be better on the libsigc++ list, but anyway...

Your example code doesn't show the definition of the Engine class - are you sure you are deriving from SigC::Object?

rather than new class Gorecki(); you should write new Gorecki; (but this won't
be your problem here.)

You shouldn't need that static_cast, once you're deriving Engine from
SigC::Object, SigC::slot(*this, &Engine::open) should be fine.

See the tutorial on the libsigc++ website for more examples.

Hope this helps,
