Unfortunately not, it only tells you who sent the message.
but since you know _you_ sent the message (by using the flag)
you probably can make it work.
Glade signals options using the glade editor is weak.
In general I create my signals and handlers programmically because of this.
and this particular problem, updating a widget without endless loop seems
common but I have not seen a well thought out (by GTK creators) way.
PNCconf goes to great lengths to overcome this and I would do it different if I
did it again (I'd use flags)
