problem not showing image in QGraphicsPixmapItem
Message 1 in thread
The below code of QT4.2 is to show image used by QGraphicsPixmapItem; but the execution can't show the png image except black background. Please give me help to resolve the problm. Thank you!!
-----------------
int main(int argc, char **argv) { QApplication app(argc, argv); QGraphicsScene scene; scene.setBackgroundBrush(Qt::black); scene.addPixmap(QPixmap("/image/pacman02.png")); QGraphicsView view(&scene); view.show(); return app.exec();}

I would try the following
Before the .addPixmap call, do the following
Q_ASSERT( QFileInfo( “/image/pacman02.png” ).exists() )
Is it supposed to be relative by chance?
Or is it a resource image and did you forget the colon in front?

Hi,
> scene.addPixmap(QPixmap("/image/pacman02.png"));
Most probably file "/image/pacman02.png" does not exist. Note that
"/image/pacman02.png" is an absolute path. You probably want the
relative path "image/pacman02.png".
