File icon to graphic view

[faldzip]

I think your problem might be here:

QPixmap(appIcon.pixmap(2,QIcon::Normal,QIcon::On))

QPixmap(appIcon.pixmap(2,QIcon::Normal,QIcon::On))

To copy to clipboard, switch view to plain text mode 

First of all QIcon::pixmap() already returns QPixmap so invoking QPixmap constructor again is not necessary (but it is not an error). The strange thing in your code is that "2"... it means that you want and pixmap of size 2x2... not so big for me. Try changing it to 32 for example and check if it helps.
For me this works fine:

QString filename = QFileDialog::getOpenFileName(this,
												tr("Choose file..."),
												qApp->applicationDirPath());
QFileIconProvider fip;
QIcon icon = fip.icon(QFileInfo(filename));
scene->addPixmap(icon.pixmap(32, QIcon::Normal, QIcon::On))->setPos(50, 50);

QString filename = QFileDialog::getOpenFileName(this,
												tr("Choose file..."),
												qApp->applicationDirPath());
QFileIconProvider fip;
QIcon icon = fip.icon(QFileInfo(filename));
scene->addPixmap(icon.pixmap(32, QIcon::Normal, QIcon::On))->setPos(50, 50);

To copy to clipboard, switch view to plain text mode

Thanks! Sorry for the double post. I have a new issue on icon grabbing with diferrent file types, should I open a new thread?
