Hello every one.

Im using Qtcreator 2.0, and Im having difficulty to show only what I placed in the Scene.
My code is like that:

ui->graphicsView->setScene(new QGraphicsScene());
QPolygon Polygon;
Polygon.append(QPoint(1,1));
Polygon.append(QPoint(1,2));
Polygon.append(QPoint(2,2));
Polygon.append(QPoint(2,1));
ui->graphicsView->scene()->addPolygon(Polygon);
ui->graphicsView->fitInView(ui->graphicsView->items().at(0),Qt::KeepAspectRatio);

The Polygone that Im inserting is showed better when it run the last command. but it still small in the QGraphicsview

Anyone knows how to solve this?

Hi,

ui->graphicsView->fitInView(ui->graphicsView->items().at(0),Qt::KeepAspectRatio);

instead of that, I think you can directly use view->setTransform() or view->scale()
