Functions

lv_obj_t *lv_indev_find_scroll_obj(lv_indev_t *indev)¶

Find a scrollable object based on the current scroll vector in the indev. In handles scroll propagation to the parent if needed, and scroll directions too.

Parameters:: indev – pointer to an indev
Returns:: the found scrollable object or NULL if not found.
