I found a working solution. I hope this can help someone else.
QBuffer b;
QSvgGenerator p;
p.setOutputDevice(&b);
p.setSize(QSize(800,600));
p.setViewBox(QRect(0,0,800,600));
QPainter painter;
painter.begin(&p);
painter.setRenderHint(QPainter::Antialiasing);
this->scene->render(&painter);
painter.end();
QMimeData * d = new QMimeData();
d->setData("image/svg+xml",b.buffer());
QApplication::clipboard()->setMimeData(d,QClipboard::Clipboard);
Thanks to everyone who took time to read my original post.

Objet: [Interest] how render a qgraphicsscene to svg and paste it to the
clipboard
Hi,
I am using the qgraphicsview/qgraphicscene framework. I am able to write file
from the drawn scene to multiple file formats, including svg using QtSvg. I
want to be able to copy the scene to the clipboard. For a bitmap copy, i am
using the following code:
// Selections would also render to the file
this->scene->clearSelection();
// Create the image with the exact size of the shrunk scene
QImage image(scene->sceneRect().size().toSize(), QImage::Format_ARGB32);
image.fill(Qt::transparent);
QPainter painter;
painter.begin(&image);
painter.setRenderHint(QPainter::Antialiasing);
this->scene->render(&painter);
painter.end();
QApplication::clipboard()->setImage(image,QClipboard::Clipboard);
which works great. However I wonder if I can do copy the scene as svg data to
the clipboard. Does anybody know how to do it ?
Thanks for any help.
Helfer Thomas
