Display Images in QGraphicsView

[marcel]

Yes, I just tested with:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QGraphicsView* w = new QGraphicsView();
    QGraphicsScene *scn = new QGraphicsScene( w );
    scn->setSceneRect( w->rect() );
    w->setScene( scn );
    w->setFixedSize( 400, 400 );
    QPixmap pix( "c:\\pix_jpg.jpg" );
    scn->addPixmap( pix );
    w->show();
    a.connect( &a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
    return a.exec();
}

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QGraphicsView* w = new QGraphicsView();
    QGraphicsScene *scn = new QGraphicsScene( w );
    scn->setSceneRect( w->rect() );
    w->setScene( scn );
    w->setFixedSize( 400, 400 );
    QPixmap pix( "c:\\pix_jpg.jpg" );
    scn->addPixmap( pix );
    w->show();
    a.connect( &a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

( yes, this is a very poor example ).

I loaded both your jpeg and some others, and also a png. All were OK.
Maybe you have some problems with your jpeg plug-in. Try loading a png instead.

Anyway, you should look at what pixmap.size() return after you load it.
