fx:constant attribute

The fx:constant attribute identifies a constant value. It is specified on an element that contains a static field with the specified name, and causes the element to resolve to the type of the referenced field.

Usage

<TableView fx:typeArguments="String">
    <columnResizePolicy>
        <TableView fx:constant="CONSTRAINED_RESIZE_POLICY"/>
    </columnResizePolicy>
</TableView>

A more concise way to achieve the same result is to use an assignment expression. Alternatively, if the constant is declared on the same class, its name can be used as a literal:

<!-- Converting "UNCONSTRAINED_RESIZE_POLICY" to the value of
     the static field TableView.UNCONSTRAINED_RESIZE_POLICY -->
<TableView fx:typeArguments="String"
           columnResizePolicy="UNCONSTRAINED_RESIZE_POLICY"/>
