Question

示例代码：public class TestDialog extends JDialog {    public TestDialog() {
    }    public TestDialog(Dialog owner, String title) {
        super(owner, title);
        init();
    }    private void init() {

        this.pack();
       
    }    @Override

            System.exit(0);
        } else {
            super.processWindowEvent(e);
        }
    }    public static void main(String[] args) {
        System.out.println("start");        TestDialog d = new TestDialog(null,"dialotTest");
        d.setVisible(true);  //对话框弹出后为什么程序继续往下走呢，线程不是应该停吗
        System.out.println("……");//关闭dialog后才应该走这呀，这是为什么？请指点
    }
}

Answer 1

这个地方改下protected void processWindowEvent(WindowEvent e) {
        if(e.getID() == WindowEvent.WINDOW_CLOSING) {
            dispose();        } else {
            super.processWindowEvent(e);
        }
    }

Answer 2

你要理解d.setVisible(true);这句话的实质，它其实只是单纯的显示JDIAOG，显示完，那么它就执行完了，转而执行下一条语句，它不同于JOpionPane.

Answer 3

你创建个模式的就行了
JDialog d = new JDialog(new TestDialog(), true);

Answer 4

setModal(true)
要用模态窗口
