Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

/*You code here*/

spinbox = lv_spinbox_create(lv_scr_act(), NULL);
lv_spinbox_set_range(spinbox, -1000, 90000);
lv_spinbox_set_digit_format(spinbox, 5, 2);
lv_spinbox_step_prev(spinbox);
lv_obj_set_width(spinbox, 100);
lv_obj_align(spinbox, NULL, LV_ALIGN_CENTER, 0, 0);

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.

Hi @W-wonderful,

The colour of widgets is changed using the style system please see the docs here

A couple of examples would be:

    lv_obj_set_style_local_bg_color( spinbox, LV_OBJ_PART_MAIN, LV_STATE_DEFAULT, LV_COLOR_BLACK);
    lv_obj_set_style_local_text_color( spinbox, LV_OBJ_PART_MAIN, LV_STATE_DEFAULT, LV_COLOR_WHITE);

I hope this helps.

Kind Regards,

Pete
