暂停执行，直到关闭子对话框 [英] Pause execution until the child dialog is closed

问题描述

我正在尝试从JFrame打开JDialog.我想暂停执行，直到关闭子对话框，但是主框架正在连续执行而没有任何暂停.我正在使用以下代码.

I am trying to open a JDialog from JFrame. I want to pause the execution until the child dialog is being closed, but the main frame is being executed continuously without any pause. I am using the following code.

什么是替代解决方案?

Class NewFrame extends JFrame

 NewFrame()

  try 
    {
       NewDialog frm = new NewDialog();
       frm.show();

       JOptionPane.showMessageDialog(null,"yes");
     }
  catch(Exception ex)
   {
   ex.printStackTrace();
  }
 }
}

在上面的程序中，我希望在关闭对话框时显示一条消息.

In the above program I want a message should be displayed when the dialog box should be closed.
