Answer 1

I have an EMF-generating PyQt QPaintEngine class here: https://github.com/jeremysanders/veusz/blob/master/document/emf_export.py. It uses the pyemf library, but I think it would be fairly easy to port to C++. Unfortunately the files are not compatible with OpenOffice as OO has pretty broken path support in EMF files. It also converts text to paths for WYSIWYG.

Answer 2

The QGraphicsView class and its associated helpers can render to a QT metafile format through the QPicture class (for which you could write a translator to EMF), to SVG through the QSVGGenerator class and to postscript/pdf through QPrinter. It can also render to bitmap formats and various other targets.

AFAIK it doesn't have a generic 'render to EMF' facility - you would have to write to something else like the QT Metafile and convert to EMF. If you only need a subset of the graphics primitives you might only need to support that subset in the translator. Otherwise you could go from SVG, which you can get directly from QT through QSVGGenerator.
