There is some confusion about its trigger logic of LV_EVENT_SHORT_CLICKED event

in lvgl v7.0.2, for LV_EVENT_SHORT_CLICKED event ,the trigger logic code is follow


if(proc->long_pr_sent == 0 && proc->types.pointer.drag_in_prog == 0) {
    lv_event_send(indev_obj_act, LV_EVENT_SHORT_CLICKED, NULL);
    if(indev_reset_check(proc)) return;
}

Why is there no criterion for point movement?If the pressing time is short, but the mouse has moved a lot during that time, and drag is not enabled, is that a short click?Reasonable?

Why can’t we consider it a click if the pointer still remained on the object?
