How to set pre-defined constants via FXML

Question

Does anymode know how to set a pre-defined constant like javafx.scene.control.Control.USE_PREF_SIZE via FXML when you create a node?
Instead of using a fixed value like this
   <Label text="Last Name:" minWidth="100" />I would like to use one of the predefined sentinel values like this.
   <Label text="Last Name:" minWidth="USE_PREF_SIZE" />The above example does not seem to work and I have the feeling that this is currently not possible at all.

How did you get that working? When I use the following file I only get a warning that "javafx" is not defined.
Defining var A seems to work but it fails on var B. It seems to be impossible to access anything outside the
java... hierarchy. Is there anything else you have to define?
<?xml version="1.0" encoding="UTF-8" ?>
<?language javascript?>
<?import javafx.scene.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.control.*?>
<StackPane xmlns:fx="http://javafx.com/fxml" >
     <fx:script>
          var A = java.awt.Component.BOTTOM_ALIGNMENT;
          var B = javafx.scene.control.Control.USE_PREF_SIZE;
     </fx:script>
</StackPane >
