Drawing text using QPainter deserves a separate explanation, not because it is complicated, but because Qt offers much flexibility in this regard. In general, painting text takes place by calling QPainter::drawText() or QPainter::drawStaticText(). Let's focus on the former first, which allows the drawing of generic text.
The most basic call to paint some text is a variant of this method, which takes x and y coordinates and the text to draw:
