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" />
(另见https://docs.oracle.com/javafx/2/api/javafx/fxml/doc-files/introduction_to_fxml.html#define_elements)
...这不适用于 Scene Builder,当我尝试打开 fxml 文件时,我检索到一条错误消息(见下文)。
Scene Builder 是否支持 fx:define 标签?
如果是:我怎样才能正确使用它?
如果不是:我在哪里可以找到包含(不)受场景生成器支持的所有标签的列表?
