@Alexandro, thank you for the code. It works nicely.

I found that it's best to set the min and max values as floats instead of int

self.min = 0.
self.max = 100.
self.value = 25.

Otherwise, the values won't update properly in python3 if the input value to valueToText() is also an integer, due to integer division
