TLFText needs to fit width of text box.

Question

I used classic text before and this code works.
var myFormat:TextFormat = dtb.getTextFormat();
     while(dtb.textWidth>=dtb.width)
          myFormat.size = int(myFormat.size) - 1;
            dtb.setTextFormat(myFormat);
          trace("best is: " +myFormat.size);
          trace("dtb.textWidth: " + dtb.textWidth);
     myFormat.size = int(myFormat.size) - 1;
     dtb.setTextFormat(myFormat);
but I need to switch the text boxes over to TLFText because we are going multi-language, and this function no longer works, I have no idea how to do the same thing with TLFText?
Thanks

Answer 1

solved it.
function fontSizeChanger(dtb:TLFTextField):void
     if(dtb.text.length > 0 && dtb.textWidth>dtb.width)
               var fmt:TextFormat = new TextFormat(dtb.textFlow.hostFormat.fontFamily,dtb.textFlow.hostFormat.fontSize);
               while(dtb.textWidth>=dtb.width)
                    fmt.size = int(fmt.size)-1;
                    dtb.setTextFormat(fmt);
