[Qt-interest] How to speed up QChar drawing? Would QStaticText help?

Hello!
Here's scenario: lots of QGraphicsItem's each draws single QChar with
painter->drawText(boundingRect(), Qt::AlignCenter, QString(char));
font is always the same.
Then these items are moved using animation. I want to speed up this to
decrease flicker.
I guess QStaticText wouldn't help much. I have single char and there's
no complicated text layout.
What are other ways?
Maybe painting char onto bitmap and then painting bitmaps in
QGraphicsItem::paint?

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
