Hello I'm trying to cancel a value change in a parameter tree.
The user enters a value, then the value is checked if supported depending on other values. If not I would like to display a warning to the user and cancel the change (reverting to the initial value). I have tried to use the sigTreeStateChanged signal to handle that, but with no success. What is the correct method to implement it?
