java - 在 JDialog 中使用 JavaFX JFXPanel 时无法看到视频

Question

我正在尝试将视频嵌入 JDialog 框中。最终我需要嵌入三个单独的视频，因此我以定义我自己的 JFXPanel 实现以供重用的方式实现了该功能。我能够运行该应用程序，当我调试它时，createScene 正在执行，但我没有看到任何可见的视频，也没有收到任何错误。我还尝试输出文本，但也不可见。我已经能够获得我想要嵌入并在纯 JavaFX 实现中显示的视频，所以我知道它不是编码或其他东西。我可以请某人检查以下代码并给我一些建议吗？如果这很重要的话，我会使用 Netbeans 作为 IDE。谢谢!
