JavaFX场景生成器是否支持<fx:define>标记?

如果我尝试在fxml文件中使用fx:define标记,例如。

<fx:define>
   <Tooltip fx:id="thetip" prefWidth="120" wrapText="true" text="Here's a tip of the day: prefWidth and wrapText attrs control the behavior of the tip."/>
</fx:define> 
<Button tooltip="${thetip}" text="Tip Button" />

(另请参见 https://docs.oracle.com/javafx/2/api/javafx/fxml/doc-files/introduction_to_fxml.html#define_elements )

…这不适用于场景生成器,当我尝试打开fxml文件时,我检索到一条错误消息(见下文)。

场景生成器是否支持fx:define标记?

• 如果是:我如何正确使用它?

• 如果没有:在哪里可以找到包含场景生成器(不)支持的所有标记的列表?
