I noticed that this macro is used at the top of the files (lvgl + python):

#define LV_OBJ_T {obj_type}

typedef struct mp_lv_obj_type_t {
    const lv_obj_class_t *lv_obj_class;
    const mp_obj_type_t *mp_obj_type;
} mp_lv_obj_type_t;

I was wondering if it’s still necessary.

if (lv_obj){
mp_lv_obj_t *self = lv_obj->user_data;
lv_obj_t *obj = (lv_obj_t *)lv_event_get_current_target(e);
if (obj){
mp_lv_obj_t *self = lv_obj_get_user_data(obj);

self->lv_obj = NULL;
}

Inside gen/stub_gen.py, function def run(json_path, lvgl_api_json_path):,
argument lvgl_api_json_path is currently unused.

Is this still a work in progress?

yes the stub generator is not finished. It has many issues that need to be hammered out.
