Roller overflow or full turn

How to
1

I have a screen with 5 rollers.
My idea is that when passing the rightmost roller from 9 to 0, the second roller automatically increases its value
for example I have. 0 0 0 0 9 I click on the roller with the 9
so I have 0 0 0 0 0 but I want it to be 0 0 0 1 0
Is there any full turn or overflow event?

No this event isnt here, but you can do your idea with LV_EVENT_VALUE_CHANGED and simple store compare previous val wth new…
