我正在尝试创建一个 JavaFX MDI 应用程序。在 JFXPanel 上使用 FXML 文件，然后在 JInternalFrame 上使用弹出式组件（如菜单和 ComboBox）会出现很多问题

现在我正在尝试使用来自 jfxtras 的 VFXWindow。我采用了其中一个VFXWindow 示例。我对所有样本都感到异常。我如何让它运行？

您似乎在 Java(FX)8 环境中使用 JFXtras 2.x 版本。Oracle 已经从 JavaFX 2 -> 8 移动了一些类，因此您需要使用 JFXtras 8.x 版本。

也就是说，我不确定开发人员是否将 VFXWindows 迁移到 JavaFX 8，事实上我在当前的源代码树中找不到 VFXWindowsTutorial1 类。然而，有 jfxtras-windows 工件... http://jfxtras.org/
