所以我继续我的战斗:Creating Java dialogs任务。现在我的JOptionPane打开带有信封覆盖的新窗口,但我无法更改此窗口的大小。另外我想让发件人的数据在左上角,接收者的数据在右下角。我怎样才能做到这一点? OptionPane本身也存在问题。点击“确定”后,它会打开屏幕左上角的小窗口。这是什么以及它出现的原因?
我的代码:JOptionPane打开另一个JFrame

我认为owca已经给了你一个非常好的推动。你不用这次尝试一下。此外,包括你有什么和你想要的东西的截图可能会有用,所以我们不必复制粘贴你的代码看到。 – OscarRyz 2010-05-28 01:50:16
