程序如下,為什麼每次運行到 Talbefrm.hide();程序就會出錯?
請高手幫忙
WindowListener c = new WindowAdapter() {
public void windowOpened(WindowEvent e) {
int confirm = JOptionPane.showOptionDialog(null,
"DO You Really Want See This Form?", "Exit Confirmation",
JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE,
null, null, null);
if (confirm == 0) {
System.out.println("111");
Talbefrm.hide();
}
}
};
