Constants in an FXML file

Couldn't find any examples on this. How do I define constants in an FXML file?

For example (where CONTENT_SPACING is the constant I want to create):

<VBox fx:controller="myapp.Controller" xmlns:fx="http://javafx.com/fxml" alignment="center" spacing="20">
    <fx:define>
        <Double fx:id="CONTENT_SPACING" fx:value="200"/>
    </fx:define>

    <VBox fx:id="content" spacing="$CONTENT_SPACING">
        <!-- My window contents would go here -->
    </VBox>
</VBox>

My code would benefit in readability if this was possible. Thanks!

Solution

  • Well, this is a bit embarrassing. It was valid FXML all along, but my IDE (IntelliJ IDEA) keeps telling me it's not. The code itself runs fine.

    I'll go file a bug report.

    Edit: Bug is fixed.
