another GtkToggleButton signal question

[Neil Zanella <nzanella gmail com>]

Hello,

Can I also rely on the fact that if a GtkToggleButton is active then a
function call
to set its active state to TRUE is not going to trigger a signal. In
general, is it true
that signal handlers are invoked when properties are CHANGED BY A FUNCTION
OR USER ACTION, and not when a function causes the given property to remain
the same?

In particular, if a toggle button state is true, then setting it to
true via a function
does not generate a signal. Is this concept true for GTK signals in general?

Thanks,

Neil
