从Swing转换为JavaFX？

>秋千 – >了JavaFx
> JFrame – >应用与实施Stage(如果在主类中扩展JFrame,可以使用Application.launch()来启动扩展Application的那个). Stage是显式JavaFx,是创建Window所必需的.您将需要使用它的实例,而不是JFrame的实例.
> JPanel – >场景&窗格(场景与JPanel匹配,但你的类应该扩展窗格.然后从窗格构建一个场景.窗格是JavaFX中的布局)
> JButton – >按键
> JLabel – >标签
>在许多情况下,删除J将起到作用……
> JOptionPane – >对话(但不总是)
> ActionListener – >事件处理程序< ActionEvent>)(需要在JavaFx中为您需要的每个动作创建一个新的方法/类,与Swing的一个方法完全相同)
