QFont font("Arial"); font.setPixelSize(14);
QFont font("Times New Roman", 12); int pixelSize = font.pixelSize();In this example, we create a QFont object named font with the Times New Roman font family and a point size of 12. We then retrieve the pixel size of the font using the pixelSize method and store it in an integer variable named pixelSize. The package library for QFont pixelSize is Qt.
