我想关闭第二个窗口~然后第一个主窗口会显示出来```可是编译都通过了```主窗口还是没有Show出来`
帮看下应该怎么改。

你只给了代码片段,让我们怎么看

不好意思```这回发完了~~我以为看这里可以看出问题```

但是你的程序用了很多过时的方法
比如show(),hide()
应该用setVisible(true) setVisible(false)来代替

我是想在第二个窗口弹出来后~~按窗口右上角的关闭来关闭窗口~~使第一次主窗口跳回出来~~
可是我这里不跳啊~~晕了```还要按Ctrl+C才能结束进程~~~

你没有为你点第二个窗口程序上的关闭加个事件啊
把关闭事件重写下..........
