Hi
Both the ScaleEntry and the SpinScale widgets have slider functions and they also have +/- adjustment. But they are not the default widget for entering values so they have to be specified when you create the dialog
For example
dialog.get_widget(“parametername”, GimpUi.SpinScale.gtype)
The gtype has two underscores each side which makes it look bold here! Anyway that is how you do it in Python. Hope that helps
