当JDialog是主窗口时，正确关闭Java程序 [英] Closing a java program properly when JDialog is the main window

问题描述

我在应用程序中有一个JDialog作为主窗口(最初是JFrame，但它显示在任务栏上是我不想要的).

I have a JDialog as the main window in my application (originally it was a JFrame but it showed in the taskbar which I didn't want).

当前我正在做

setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);

，当我单击退出按钮时:

and when I click an exit button:

frame.dispose();

但是该过程似乎仍然在后台徘徊

But the process still seems to hang around in the background

JFrame的JFrame.EXIT_ON_CLOSE似乎可以满足我的要求.

JFrame had JFrame.EXIT_ON_CLOSE which seemed to do what I wanted.

如何正确关闭我的应用程序?

How can I close my application properly?

推荐答案

您可以添加

  System.exit(0);

您希望程序结束的位置，也许紧接在dispose()行之后.

where you want the program to end, maybe immediately after the dispose() line.
