Increment
~~~~~~~~~
:cpp:expr:`lv_obj_add_subject_increment(obj, subject, step, min, max)`
:cpp:expr:`lv_obj_add_subject_increment_event(obj, subject, step, min, max)`
Increments the subject's value by `step`, clamped between `min` and `max`.
For example:
:cpp:expr:`lv_obj_add_subject_increment(button1, subject1, LV_EVENT_CLICKED, 5, -10, 80);`
:cpp:expr:`lv_obj_add_subject_increment_event(button1, subject1, LV_EVENT_CLICKED, 5, -10, 80);`
This will increment `subject1` by 5 when `button1` is clicked.
The resulting value will be constrained to the range -10 to 80.
