javaFX关闭视频而不关闭主程序（特定情况）

Question

我正在构建一个程序来完成一个想法，那就是视频播放器，这是用javafx制作的，但是该程序是在普通的java中，我找到了一种播放视频的方法，但是真正的问题是，当关闭时右上角的X，视频的音乐不会停止，我尝试代替frame.setDefaultCloseOperation（JFrame.DISPOSE_ON_CLOSE）;把frame.setDefaultCloseOperation（exit（））;仍然在代码中。

编辑：我添加了实现WindowListener和所有抽象方法的方法，但是在关闭或打开窗口时不会调用它们（我使用System.out.println（）来测试是否被调用）。
