Olá, Galera.
Alguém já teve algum problema do tipo. Tenho um JFrame que chama um JDialog, ao tentar fechar a JDialog através do “X”, eu sou obrigado a clicar 2 vezes no “X” para fechar a JDialog, alguém sabe me dizer o que pode ser. Fiz um teste com um JFrame com as mesmas rotinas da JDialog e o mesmo fecha sem problema algum. Nesta JDialog somente tenho uma JTable que é alimentada através de um select.
Se alguém puder me ajudar agradeço,
Abs,
Marcos
Oi,
Acho que esta sendo criado 2 JDialogs e você não esta percebendo… rs
Tchauzin!
Que bela Ajuda !!!
Oi,
Tá. Passa a criação do JDialog ai.
Tchauzin!
Segue o código:
Chamada do JDialog:
private void oM3ButtonSearch1ActionPerformed(java.awt.event.ActionEvent evt) {
DisplayQueryResults newUser_pl = new DisplayQueryResults(this, true);
newUser_pl.setVisible(true);
}
private void oM3ButtonSearch1ActionPerformed(java.awt.event.ActionEvent evt) {
DisplayQueryResults newUser_pl = new DisplayQueryResults(this, true);
newUser_pl.setVisible(true);
} Rotinas da JDialog

Agora Sim,
Valeu pela ajuda.
