Using Typeface.js within a GWT app

I am looking for some sample Java code demonstrating how to get AJAX content displayed into a custom font using Typeface.js within a GWT app. I have tried a little bit by calling the following native function

    native void Typeface_renderDocument() /*-{ 
        $wnd._typeface_js.renderDocument();
    }-*/;

• after having filled the relevant widget with the AJAX content, and

• after calling the following function on the widget :

  void applyTypeface(Widget widget) {
      widget.addStyl开发者_开发技巧eName("typeface-js");
      widget.getElement().getStyle().setProperty("fontFamily", "Helvetiker");
      Typeface_renderDocument();
  }
  

...where Helvetiker is a custom font (actually available from Typeface.js fonts page (http://typeface.neocracy.org/fonts.html). But the above attempt didn't work.

Any suggestions are very welcome, I am bit stuck here...

A guess, but try running Typeface_renderDocument() in a DeferredCommand -- perhaps those style changes aren't visible in the DOM at the point that the JS executes.
