No good. I’m in a script and using wheel right or left and need to know if I’m adjusting shutter speed or ISO.
I think what caefix may be been suggesting is move the wheel one click (from script) and see which changes (from propcases). You could then do one click in the opposite direction to undo the change. Have to be make sure it's not already at a limit though, or detect when nothing changes.
If it's not in a propcase (which I definitely wouldn't expect it to be), any other options for detecting that state likely require reverse engineering.
