Hi,
here it is a patch to add drag-start and drag-stop signals to mx-slider.
I don't know if Mx has a bugzilla, in case let me know so that I can
upload the patch there.
Thanks and Regards,
Massimo

Hello!
It seems to me that the mx_slider doesn't provide a handle-moved signal.
Is there a reason why it doesn't?
Hi, do you mean something equivalent to listening to "notify::value"?
"notify::value" is nice but having drag-start / drag-end would be the
best choice in my opinion.
Right now to detect that the handle has been pressed I have to connect
to captured-event and then parse the event type (button-press-event etc.).
Regards,
Massimo
