Set border color of LED object

Feature request

I’ve pushed a fix to send events as @embeddedt suggested. I’ve tested with this code:

static void draw_event_cb(lv_event_t * e)
{
    lv_obj_draw_part_dsc_t * dsc = lv_event_get_param(e);
    if(dsc->part == LV_PART_MAIN) {
        dsc->rect_dsc->border_color = lv_color_hex3(0x0f0);
    }
}

...

    lv_obj_t * led2  = lv_led_create(lv_scr_act());
    lv_obj_align(led2, LV_ALIGN_CENTER, 0, 0);
    lv_led_set_brightness(led2, 150);
    lv_led_set_color(led2, lv_palette_main(LV_PALETTE_RED));
    lv_obj_set_style_border_width(led2, 3, 0);
    lv_obj_add_event_cb(led2, draw_event_cb, LV_EVENT_DRAW_PART_BEGIN, NULL);
