LVGL V8之 column and row grid gap

• 行间距动画回调函数

static void row_gap_anim(void* obj, int32_t v)
{
    lv_obj_set_style_pad_row(obj, v, 0);
}

• 列间距动画回调函数

static void column_gap_anim(void* obj, int32_t v)
{
    lv_obj_set_style_pad_column(obj, v, 0);
}

• Demonstrate column and row gap

static void lv_example_grid_5(void)
{
    /*60x60 cells*/
    static lv_coord_t col_dsc[] = { 60, 60, 60, LV_GRID_TEMPLATE_LAST };
    static lv_coord_t row_dsc[] = { 45, 45, 45, LV_GRID_TEMPLATE_LAST };
    /*Create a container with grid*/
    lv_obj_t* cont = lv_obj_create(lv_scr_act());
    lv_obj_set_size(cont, 300, 220);
    lv_obj_center(cont);
    lv_obj_set_grid_dsc_array(cont, col_dsc, row_dsc);
    lv_obj_t* label;
    lv_obj_t* obj;
    uint32_t i;
    for (i = 0; i
