LVGL V8之Base object

创建基本obj对象

static void lv_example_obj_1(void)
{
    lv_obj_t* obj1;
    obj1 = lv_obj_create(lv_scr_act());
    lv_obj_set_size(obj1, 100, 50); // 设置大小
    lv_obj_align(obj1, LV_ALIGN_CENTER, -60, -30); //偏移中心-60，-30处对齐
    static lv_style_t style_shadow;
    lv_style_init(&style_shadow);
    lv_style_set_shadow_width(&style_shadow, 10); //阴影宽度
    lv_style_set_shadow_spread(&style_shadow, 5);// 阴影延伸
    lv_style_set_shadow_color(&style_shadow, lv_palette_main(LV_PALETTE_BLUE));
    lv_obj_t* obj2;
    obj2 = lv_obj_create(lv_scr_act());
    lv_obj_add_style(obj2, &style_shadow, 0); //obj2对象添加阴影style
    lv_obj_align(obj2, LV_ALIGN_CENTER, 60, 30); //偏移中心60，30处对齐
