Re: cancelling/aborting an emitted signal

the "new" handler won't change the behaviour of
gtk_toggle_button_get_active().  if the button is toggled, this
function will return TRUE, and FALSE otherwise. 

what the handler will do is to affect the effect of a button
press/release. if it returns TRUE *and* calls
gtk_signal_emit_stop_by_name(), the button press will have no action
at all - the button will not enter the toggled state at all.

it doesn't revert it, it stops the toggle from even occuring.

you may well have to do that, since GTK+ by default has key bindings
that will toggle the button.
