trying to change the background colour of the label
not sure what is wrong here

Code: [Select all] [Expand/Collapse]

lv_obj_t *headingLabel = lv_label_create(active_screen, NULL);
 
    lv_label_set_text(headingLabel, "Heading"); /*Set the labels text*/
 
    lv_obj_set_pos(headingLabel, lv_obj_get_width(list1), 0);
    lv_obj_align(headingLabel, NULL, LV_ALIGN_IN_TOP_MID, 0, 0);
    lv_obj_set_style_local_text_color(headingLabel, LV_LABEL_PART_MAIN, LV_STATE_DEFAULT, LV_COLOR_BLACK);
// set background colour of label
   lv_obj_set_style_local_bg_color(headingLabel, LV_LABEL_PART_MAIN, LV_STATE_DEFAULT, LV_COLOR_PURPLE);
    lv_obj_set_style_local_text_font(headingLabel, LV_LABEL_PART_MAIN, LV_STATE_DEFAULT, &lv_font_montserrat_42);

Not the right place to ask.

If I remember correctly, it is something like that the text background is not opaque by default. Try setting the opacity to full, otherwise you’re indeed far more likely to get a response on the LVGL forum
