Thanks, that seems to work.

I'm not sure what happens when the user changes the value using the keyboard 
though. It's probably not that much of an issue, because value changes will 
be less frequent (limited by the keyboard's repeat rate), but still... it 
might become a problem somewhere down the road.

Well, I guess if necessary I could still set a simple flag before each 
set_value() call, and check for that in the value-changed callback...
