How about this:

#include 
#include 
#include 
#include 

int main(int argc, char* argv[]) {
    QApplication app(argc, argv);
    QGraphicsScene scene;
    scene.addText("Hello, world!");
    QRect rect(50, 50, 100, 100);
    QGraphicsRectItem* recti = scene.addRect(rect);
    QGraphicsView view(&scene);

    // Set scale for the view
    view.scale(10.0, 5.0);

    // Set the inverse transformation for the item
    recti->setTransform(view.transform().inverted());

    view.show();
    return app.exec();
}

As you can see the text is scaled up but the rectangle is not. Note that this does not only prevent the scaling for the rectangle but and other transformation.
