Re: [flexcoders] Fail to apply UITextFormat to UITextField in custom Component
Instead of using defaultTextFormat, try setting the text and then calling
myText.setTextFormat(myFormat). Also calling addchild and then setting the
formatting may make a difference but it's been a while since i looked at
this stuff so it might not. If neither of these things help and i have some
time later today I'll try to get into it.

no, all of the formatting is overridden.
Functionality for setting format based on style is in the
UITextField class,
I think the function is validateNow()
thanks dan, that pointed me to the right direction. I traced
validateNow() in UITextField where the format is set using styles -
overriding all of the formatting that might have been applied using
UITextFormat. I did toggle styleChangedFlag to false and voilà - all
the formatting using UITextFormat were applied. Now I have the choice
to extend UITextFormat and to override validateNow() or just use
Styles for all the formatting and forget about UITextFormat, which is
probably the recommended way - just getting started with flex you see.
thanks again, solved.

For future reference, I asked about font type because embeding fonts
incorrectly could account for the described behavior (as I originally
understood it), and the rendering engine for device fonts (in very
few and
specific cases) also has its own quirks.

Well, i'm not really comfortable with this but I think I need to look
closer at styles, since formats seem to get overriden when a
