Ola pessoal!! sou novo aki no forum. O negocio e o seguinte eu sou estudante de engenharia e meu professor de progamação pediu un trabalho pra quinta o problema e q meu programa naum ta funcionando e eu naum sei o pq. Alguem podia da uma lida no meu codigo pra v se axa um erro?Se pude vlw!!!
ps:Eu cai numa turma de Java por engano então pega leve!!!

aki ta o codigo,era pra se um editor grafico q desenha retangulos e circulos de tamanho fixo e apaga ou um circulo ou um retangulo ou o ultimo,:

Mas qual é o erro que dá? Dá-nos mais informações, assim não temos de passar a pente fino todo o código e olhar apenas para zonas especificamente relacionadas com o erro/anómalia.

noidPJ · Setembro 24, 2008, 5:58pm

o erro e naum estar desenhado quando se clica na janela

SrFabioPJ · Setembro 28, 2008, 8:20am

Usa j.setVisible(true) ao invés de j.show();
