Apply Text Filter Dynamically

How can I add a glow filter to a textfield via actionscript? I know the procedure for doing the same thing with a movieclip, but the TextField class (and TextFormat) don’t seem to accept filters as a property?

What I have so far:

import flash.filters.*;

var text_glow:GlowFilter = new GlowFilter(0xFF0000, 80, 10, 10, 100, 3, false, false);

var some_txt:TextField;

//Want to apply filter to text field
