RE: More info about signals

	Hi,

thanks for your answer.

It is a pity that this is not explained. The tutorial doesn't speak about
it, and the API reference just explains what the arguments are. Useful when
you already know how it works but not for the beginner.

Could you point me to some code using this ? It would be better for me for
understanding how it works.
