我们在做JavaFX的时候,编写界面是个非常头疼的问题,因为原生JavaFX是没有拖拉拽界面的。
为了解决这个问题。我们用了Oralce的 JavaFX Scene Builder 2.0 或者 Gluon的 SceneBuilder (下图是后者)
我们设计好界面后拿到了一段xml。

但是我们还需要将XML里的控件和事件反序列化出来,这就比较麻烦了。
所以我写了这个工具:
https://www.sanshu.cn/tools1/javafx_sence_ass/
你可以在第一个文本框里输入Scene Build的代码,然后填写类名(可以为空)并且点击生成按钮。
就会生成
所有的变量的类(只会解析 fx:id)
所有事件的代码。
如下图。
总体来说还是很方便的。
