How to set fontFamily with an embedded font of a textFlow ?

Question

Hy,
When I create a TextFlow without use any component of the flex SDK (4.0.13827) and then I try to change or apply a FontFamily of an embedded font, it doesn't work. Whereas when I use a component like RichEditableText or Label, it works.
Bellow the code I wrote for my test :
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                            xmlns:s="library://ns.adobe.com/flex/spark"

                            creationComplete="creationCompleteHandler(event)"
                            width="800" height="600"

          @namespace s "library://ns.adobe.com/flex/spark";
          @namespace mx "library://ns.adobe.com/flex/mx";
          @namespace local "*";
          @font-face {
               src:                         url("assets/Fonts/arial.ttf");

Please, help me...
Thank you very much...

Answer 1

Thank you very much,
I finally found the solution using the swfContext :
use namespace mx_internal;
myTextFlow.swfContext = ISWFContext(getFontContext("myFontName", false, false, FontLookup.EMBEDDED_CFF));
It works fine both with a dynamic component like RichEditableText or a dynamic textflow with a ContainerController.
Thanks
