In GIMP 2.10 python plugins there was a type of input param PF_SLIDER
with (min, max, step)
settings.
In GIMP 3.0.2 I use procedure.add_int_argument
+ dialog.get_scale_entry
to make slider widget, but there is no way to set step
value for slider.
Is it ever possible to make slider widget with step values in gtk3?
