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.
