Thank you for your answer. You are right, after some search i found in the [pyvcp_widgets.py] file in the [pyvcp_scale] class this code fragment:
if initval < min_:
self.value=min_
elif initval > max_:
self.value=max_
else:
self.value=initval
I change it to:
if max_ > min_:
if initval < min_:
self.value=min_
elif initval > max_:
self.value=max_
else:
self.value=initval
else:
if initval > min_:
self.value=min_
elif initval < max_:
self.value=max_
else:
self.value=initval
Now it working both ways. It will be nice if it is added to the next release. When you use verical scale is more user friendly to have the lower value in the bottom.
