Additionally, you can also draw text using the QPainterclass. All you need to do is to call QPainter::setFont() to set the font properties before calling QPainter::drawText(), like so:
QPainter painter;
painter.begin(this);
// Draw Text
painter.setFont(QFont("Times", 14, QFont::Bold));
painter.drawText(QPoint(20, 30), "Testing");
// Draw Line
painter.drawLine(QPoint(50, 60), QPoint(100, 100))
