混合Java swing和JavaFX

Question

我在netbeans平台项目中遇到了一些麻烦，我把swing和javafx混合起来。

我有两个标签，其中一个标签有一个旋钮，另一个标签包含一个javafx TreeTableView。当按下按钮时，应该在TreeTableView中添加一个新行，但我无法实现这一点。

在添加新节点之前和之后，我会递归打印树。

Root before add: 
Root
-Child 1
-Child 2
Root after add: 
Root
-Child 1
-Child 2
-New child

因此，基础数据模型发生了变化，但UI并未反映这些变化。

任何指向我所缺少的内容都会有所帮助。
