how to set toggle/radio buttons without "clicked"

[Paul Barton-Davis <pbd Op Net>]

i have some radio and toggle buttons. they can be set (in-)active by
the user+mouse, or programmatically as a result of data read from
an external input source.

if i use gtk_toggle_button_set_active() for the programmatic setting,
then the "clicked" signal is emitted. How can i set the button states
in a way that doesn't make it appear that there was user interaction ?
