[solved]drag a picture to a different application

[Qiieha]

hi
I want to drag a picture to a different application (f.e. gimp). It works fine with that code:

QMimeData* mimedata = new QMimeData;
    mimedata->setImageData(QImage("/home/user/picture.jpeg"));
    QDrag *drag = new QDrag(this);
    drag->setMimeData(mimedata);
    QPixmap& pic = *picture;
    drag->setPixmap(pic);
    drag->exec(Qt::MoveAction);

QMimeData* mimedata = new QMimeData;
    mimedata->setImageData(QImage("/home/user/picture.jpeg"));
    QDrag *drag = new QDrag(this);
    drag->setMimeData(mimedata);
    QPixmap& pic = *picture;
    drag->setPixmap(pic);
    drag->exec(Qt::MoveAction);

To copy to clipboard, switch view to plain text mode 

But there is a problem. The picture is in the application, but it doesn't point to the picture on the file system. It's just a paste command. Does anybody know what I have to do?

thanks
