Question

我试图制作一个发射器。它工作正常，除了当我按下选项＆＃39;按钮它在角落里有一个小窗口。我该如何防止这种情况？

现在选项框架正在运行：y http://gyazo.com/c16c5370d9411c51f0bf732be6f0563e.png

你可以看到角落里的小窗口。当Option框架出现时，它不会消失。

Answer 1

在你的OptionsButton.addActionListener（变量的名字不是很糟糕，不应该以大写字母开头）中，你创建了一个{J}的Working对象，它出现了。

但是，在您的Working课程（真正糟糕的名字）中，您延伸JFrame工作并显示final JFrame frame属性。

这就是出现两个窗口（JFrame）的原因删除final JFrame frame中的Working，然后使用this！
