Flex 4.6: embedded fonts not applied to TextField

问题

I am trying to use embedded fonts (Flex 4.6) in a UITextField. As long as I use a font that is registered with Windows, it works fine, but for a font not registered, the UITextField defaults to TimesRoman (or something similar)

Note that when I check to see if the font is embedded, it returns True (FlexGlobals.topLevelApplication.systemManager.isFontFaceEmbedded(txtFormatCoda))

So what am I missing?

In the code below, if I add the font Kredit to Windows Font, the UI text field appears in Kredit font, but if I remove it from Windows/font directory, the field appears in TimesNewRoman (default font).

Thanks Mahesh

Actually this worked for me:

var comp:UIComponent = new UIComponent();
comp.setStyle('fontFamily', fontName);                      

Basically I had to do setStyle on the UIComponent which is the parent of this UITextField. I wish Adobe would document this.

Below code may help you: - I have commented one line and modified style tag ...
