[pygtk] Check if value-changed signal is emitted by user action

[Dominic Sacré]

Hi,

Is it possible to determine if a value-changed signal (e.g. from a gtk.Scale) 
is caused by user action, or programmatically by calling set_value()? Or is 
there another way to achieve a similar effect?

I'm using the value-changed callback to send the new value to my backend 
(asynchronously). But the GUI also needs to respond to notifications from the 
backend, by calling set_value().
Now the GUI and the backend updating each other in this way causes all kinds 
of problems. I'd like to assume that if the value change is in response to a 
notification from the backend, there's no need to send the value to the 
backend again. Is there a reasonable way to accomplish this?


Thanks,

Dominic
