That's exactly what I'm trying to do, simulate a menu item click. Same set of
questions, though. I don't know how to use it. I see the page:
_____________________________________
g_signal_emit_by_name ()
void g_signal_emit_by_name (gpointer instance,
const gchar
*detailed_signal,
...);
Emits a signal.
Note that g_signal_emit_by_name() resets the return value to the default if no
handlers are connected, in contrast to g_signal_emitv().
instance : the instance the signal is being emitted on.
detailed_signal : a string of the form "signal-name::detail".
... : parameters to be passed to the signal, followed by a location for the
return value. If the return type of the signal is G_TYPE_NONE, the return
value location can be omitted.

But I've been out of it so long I'm not sure how to make use of that.
