QTransform transform; transform.translate(50, 0); qDebug() << transform.m31(); // Output: 50
QTransform transform = QTransform::fromTranslate(20, -10); qDebug() << transform.m31(); // Output: 20This code creates a QTransform object using the fromTranslate() static function to set the horizontal and vertical translations to 20 and -10, respectively. The m31 property of the transform object returns 20, indicating the horizontal displacement. Package Library: Qt Core Library.
