Hi,
I do not know if this has been dealt with elsewhere, but IMO it would be useful to have a condensed form of the API function prototypes in the API section for each widget.
For example for labels,
Function List,
lv_obj_t * lv_label_create(lv_obj_t * parent);
void lv_label_set_text(lv_obj_t * obj, const char * text);
void lv_label_set_text_fmt(lv_obj_t * obj, const char * fmt, ...) LV_FORMAT_ATTRIBUTE(2, 3);
void lv_label_set_text_static(lv_obj_t * obj, const char * text);
void lv_label_set_long_mode(lv_obj_t * obj, lv_label_long_mode_t long_mode);
void lv_label_set_recolor(lv_obj_t * obj, bool en);
void lv_label_set_text_sel_start(lv_obj_t * obj, uint32_t index);
void lv_label_set_text_sel_end(lv_obj_t * obj, uint32_t index);
char * lv_label_get_text(const lv_obj_t * obj);
lv_label_long_mode_t lv_label_get_long_mode(const lv_obj_t * obj);
bool lv_label_get_recolor(const lv_obj_t * obj);
void lv_label_get_letter_pos(const lv_obj_t * obj, uint32_t char_id, lv_point_t * pos);
uint32_t lv_label_get_letter_on(const lv_obj_t * obj, lv_point_t * pos_in);
bool lv_label_is_char_under_pos(const lv_obj_t * obj, lv_point_t * pos);
uint32_t lv_label_get_text_selection_start(const lv_obj_t * obj);
uint32_t lv_label_get_text_selection_end(const lv_obj_t * obj);
void lv_label_ins_text(lv_obj_t * obj, uint32_t pos, const char * txt);
void lv_label_cut_text(lv_obj_t * obj, uint32_t pos, uint32_t cnt);
Obviously the function names and parameters could eventually link to appropriate detail about them if clicked on.
