This is the good way to do it, but if the method doesn't take any
parameter, it won't change anything.

The problem is that your method doesn't take a parameter, while it
should have at least one : the signal handler should take at least one
parameter: the signal sender, plus any other parameters the signal
takes. So, if you're connecting to a MenuItem's activate signal, your
handler should take a MenuItem argument. (The comments from Jan are
also relevant if you're using GtkBuilder)

btw, when you say a crash on windows, you mean you didn't test
somewhere else, not that it works, right?

HTH,
