I tried, but it does not work. In fact, I have a global GUI refresh
method, called in my spinbutton handler. I call the stop_emission()
method after that global refresh, where I have several set_value(),
set_text() and so. As far as I understand, the stop_emission() call will
block only the first set_value() emited signal?
When entering in a signal callback and calling a set_value() method, is
the value-changed signal emited/handled immediatly, or only at the end
of the callback, after it returns?

Didn't find a way yet :o(
