如题所述
CS结构系统的退出如下:public void init() {
this.setTitle("用户登录界面");
this.add(createCenterPane());
this.setDefaultCloseOperation(this.DO_NOTHING_ON_CLOSE);
this.setSize(new Dimension(450, 335));
this.setLocationRelativeTo(null);
// this.setVisible(true);
this.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
int choose = JOptionPane.showConfirmDialog(null, "是否要退出登录界面?",
"系统提示:", JOptionPane.YES_NO_OPTION);
if (choose == JOptionPane.YES_OPTION) {
System.exit(1);
}
}
});
}其中this为JFrame对象。BS结构的退出直接用windows.close()方法就行了!
