How-to

Same question, diferent LVGL version since there is nothing about “LV_SPINNER_PART_BG” and so on, in v8

Is there any way to change the spinner’s thickness?

Thanks

I haven’t compiled it but this should do the trick:

    uint32_t desired_thickness = 30;
    lv_obj_set_style_arc_width(spinner, desired_thickness, LV_PART_INDICATOR);
    lv_obj_set_style_arc_width(spinner, desired_thickness, LV_PART_MAIN);

Thanks, your solution works like a charm.

I have tried different approach

const lv_style_const_prop_t const_spinner_style[] = {
		LV_STYLE_CONST_ARC_WIDTH(5),
	};

LV_STYLE_CONST_INIT(spinner_style, const_spinner_style);

This only change width of the rounded circle. How to change the inner one?

I think you just need to add spinner_style to both LV_PART_INDICATOR to LV_PART_MAIN and it should work (not sure if you’re doing that already).
