GWT - What's the shortest way of simply sharing strings and number constants between Java code and UiBinder files?

Question

Can someone post an example of the shortest way of sharing a (preferably static final) string or number constant between Java code and UiBinder XML, where I can use the constant either in an attribute:

<g:TextArea width="...px"/>

or in a value:

<g:Label>...</g:Label>

I can't seem to find an example of this, only text from a file, which I don't want.

Answer 1

static fields (and enum constants) can be used with a simple <ui:import>:

<ui:import field="com.example.Pojo.CONSTANT" />

or

<ui:import field="com.example.Pojo.*" />

and then simply:

<g:Label text="{CONSTANT}" />

or

<g:Label><ui:text from="{CONSTANT}"/></g:Label>
