Render existing Qt Widget into SVG

Question

I have an exisiting Graph displayed as QWidget which I can already save to a bitmap using grab():

QPixmap image = grab();

Is there a Possibility to save that widget also to .svg?

Thanks!

QSvgGenerator generator;
generator.setFileName(path);
generator.setSize(widget->size());
generator.setViewBox(widget->rect());
generator.setTitle(tr("Your title"));
generator.setDescription(tr("some desscription"));
widget->render(&generator);

Thanks! Works semi-well… the Generator produces a invalid SVG-File (EOG and Inkscape can not open them. Error domain 1 code 64 on line 18 column 6 of […]/Chart.svg: XML declaration allowed only at the start of the document I can understand this: Viewing this in a text editor reveals several xml tags.

Probably this error: bugreports.qt-project.org/browse/…

This page describes a potential workaround for that bug.
