        <para>
            <literal>dragrect</literal> arrasta um ou mais retângulos para
            qualquer lugar da tela. A matriz rect 4xn define os retângulos. Cada
            coluna de <literal>initial_rect</literal> deve conter a posição inicial do
            retângulo como valores [x_esquerdo;y_topo;largura;altura]. Quando um botão
            é clicado, <literal>dragrect</literal> retorna as definições dos
            retângulos finais em <literal>final_Rect</literal>.
