UiBinder How To : create resuable component in ui.xml

I have this component with a @UiConstrutor annotation : 

@UiConstructor
public SearchWidget(Widget filterWidget, Widget resultWidget) {
  ...
}

in the ui.xml, I must write something like :

<SearchWidget filterWidget="" resultWidget=""/>

The problem is that I would like to be able to build a complex widget apart in ui.xml and use in the <SearchWidget> tag, something like :

<with field="filterWidget">
  <Widget>
  ...
  </Widget>
</with>

<With field="resultWidget">
  <Widget>
  ...
  </Widget>
</with>

And then use it like : 

<SearchWidget filterWidget="{filterWidget}" resultWidget="{resultWidget}"/>

Is their an existing approaching syntax?

You can try to use @UiChild annotation (if you can replace constructor dependencies by corresponding methods). See corresponding javadoc with example.

Two new methods:

@UiChild SearchWidget#addFilterWidget(Widget w)
@UiChild SearchWidget#addResultWidget(Widget w)

UiBinder (you need to declare new p namespace for your custom widgets):

<p:SearchWidget>
    <p:filterWidget><p:Widget>...</p:Widget></p:filterWidget>
    <p:resultWidget><p:Widget>...</p:Widget></p:resultWidget>
</p:SearchWidget>
