Merci beaucoup pour votre réponse. Cela aussi ça fonctionne.

#include <QApplication> 
#include <QWidget> 
#include <QVBoxLayout> 
#include <QGraphicsView> 
#include <QGraphicsTextItem> 
#include <QGraphicsScene> 

int main(int argc, char *argv[]) 
{ 
    QApplication a(argc, argv); 
    QWidget *window = new QWidget; 
    window->resize(300, 200); 
    QVBoxLayout *layout = new QVBoxLayout(window); 
    QGraphicsScene *scene = new QGraphicsScene(window); 
    QGraphicsView *view = new QGraphicsView(scene); 
    QGraphicsTextItem *text = scene->addText("Hello World"); 
    layout->addWidget(view); 
    window->show(); 
    return a.exec(); 
}
