Re: Signals in gtk

Thanks for the response.
I have tried both gtk_signal_connect and gtk_signal_connect_after, but they did not work. I did not try gtk_emit_stop because the API reference says that it is deprecated and should not be used. I was wondering if I should use g_threads and g_mutex, but I don't have any experience with them and am not sure if that is the right approach.

I would recommend to look at this URL first:

http://developer.gnome.org/doc/API/2.0/gtk/gtk-signals.html

_sginal_connect (...)
_signal_connect_after (...)
_signal_emit_stop... (...)

Those functions should handle your request.
I've omitted prefix for functions, because it would be "g_" for GTK-2.0
and "gtk_" for GTK-1.2.
