                number[j + 1] = number[j];

            item->setItemColor(RectItem::CYAN);

            number[j + 1] = temp;
            rect[j + 1] = item;
        }

        emit finished();
    }

the ideal result of the code is：https://visualgo.net/en/sorting (choose [insert_sort])。

but the actual result is：

I checked many times, but i didn't find any error. Look the error in the above picture, I guessed that there may be some problem in item pointer array, but I checked it carefully, no errors.

solved, setPos will not change the item's positon.
