I'm trying to display a little square of solid color.
I've created a QGraphicsView widget myGraphicsView and call:
ui->myGraphicsView->setBackgroundBrush(QBrush(Qt::red, Qt::SolidPattern));
But it stays white. What am I doing wrong?

You need to set the QGraphicsScene to the QGraphicsView before anything is drawn:
ui->myGraphicsView->setScene(myScene);
