You might want to check out my sample chapter at:

It is correct to use gtk_signal_emit() in object/widget implementation,
and you can use it if the signal is GTK_RUN_ACTION. You can't use it for
any random signal though, because emitting the signal may require special
preparation or shutdown. So you need to use the API that comes with the
object, rather than emitting signals yourself.
