GtkToggleButton signals question

[Neil Zanella <nzanella gmail com>]

Hello,

I would like to know whether the following behavior is reliable, since
it is not documented
in the API reference:

When I press a GtkToggleButton (suppose the button goes from being
pressed out to
pressed in), I notice that the "toggled" signal is emitted _AFTER_ the
button becomes
pressed in, not before.

Can I rely on this behavior?

Also, how is the "toggled" signal different from the "clicked" signal
pertaining to the
GtkButton widget from which GtkToggleButton inherits?

Thanks,

Neil
