Oi estou com um problema no seguinte, eu mostro uma tabela no meu programa, e quando eu abro outra tabela ela fica em cima da anterior e quando vou clicar nela aparece apenas a anterior, então gostaria de saber como eu faço pra fechar essa tabela anterior, eu pensei em um botao chamado sair, ou até mesmo no botão aonde abre a tabela, alguem pode me ajudar mostrando o comando que faria isso.

muito obrigada

Remova a sua tabela do Panel.

Exemplo:

seuJPanel.remove( suaJTable );

Não sei se é essa a sua duvida , se não poderia postar seu codigo ?

Só não entendi qual arquivo você quer fechar… =D

Se não for incomodo, poderia alterar o titulo para “fechar janela”, só para quando outros for consultar…

Colocar [RESOLVIDO] no titulo do topico quando encontrar a solucao é legalz tbm…

ajude a comu!

Testa ai , Espero que funcione , ou pelo menos chegue perto de funcionar.

Oi Rafael, muito obrigada pela ajuda, mas aconteceu o seguinte

no trecho que está no if que vc inseriu ele ta dando erro na linha

jPanelRodape.remove( tabelaDBF );

pois ele está considerando que não existe nenhuma tabelaDBF ali,

como faço pra resolver isso?

brunajeniferf ,

Boa tarde !

Modifiquei a linha 135,321,325 tenta agora.

continua a mesma coisa, eu abro uma tabela ta ok, ai quando vou abrir uma nova pra substitui, essa nova aparece

mas quando clica nela, ou tenta mover na barra de rolagem, aparece a tabela anterior novamente.

brunajeniferf 25 de jul. de 2011

Tava pensando se ao invés de remover a tabela dentro da ação do button, se não há como fazer um if que funcione da seguinte maneira:

se o button tabela ja foi clicado anteriormente remove a tabelaDBF

else

se a tabela nao foi clicada não remove

Tem como fazer assim, colocar um if dessa maneira a cada vez que o button tabela foi clicado?

Porque o que entendi do que vc fez, ele não removia a tabela que fora gerada com a ação do button e sim a tabela que estava vazia
criada fora da ação do button.

Muito Obrigada pela ajuda

brunajeniferf 29 de jul. de 2011
