Is it possible to easily change the button text? I’ve tried a few things, but I usually end up with memory leaks as not all memory is/can be released.
What about something like this:
static char btn1[16] = "First";
static char btn2[16] = "Second";
static const char * map[] = {btn1, btn2, ""};
lv_obj_t * btnm = lv_btnm_create(lv_scr_act(), NULL);
lv_btnm_set_map(btnm, map);
btn2[0] = 'X';
lv_btnm_set_map(btnm, map);
