How to open svg file in QT (QGraphicsView)

Question

How to open svg file like png file. For example it works for png file:

scene=new QGraphicsScene(QRect(10, 10, 680, 520));  
view=new QGraphicsView(this);
image=new QGraphicsPixmapItem(QPixmap("example.png"));

scene ->addItem(image);   
view ->setScene(scene);   
view ->setGeometry(QRect(270, 35, 700, 540));

Any ideas?

Solution

As per my comment, you could use QGraphicsSvgItem as per documentation:

QGraphicsSvgItem::QGraphicsSvgItem(const QString & fileName, QGraphicsItem * parent = 0)

Constructs a new item with the given parent and loads the contents of the SVG file with the specified fileName.

So, you would basically write something as follows:

 QGraphicsSvgItem *item = new QGraphicsSvgItem("example.svg");

You can also follow th example in the documentation if you wish to use it with the QSvgRenderer.

QSvgRenderer *renderer = new QSvgRenderer(QStringLiteral("example.svg"));
QGraphicsSvgItem *item = new QGraphicsSvgItem();

item->setSharedRenderer(renderer);
item->setElementId(QStringLiteral("example"));

Here you can even find a more sophisticated example of doing this:
