Having a quick look at the PGF documentation, you could write a Qt paint device to write some sort of PGF output. The main problem would be text. It looks like you just write latex text, so I don't know how you'd get the spacing or font sizes correct, or insert unicode symbols (perhaps would work in xetex). You could export the text as curves, but that would probably defeat the reason for exporting in PGF in the first place. If you want to write latex text directly, ignoring the sizing issues, etc, you'd have to replace the veusz text rendering code. This code is at a higher level than the Qt paint device, making this difficult. I'm also planning to add code which would make label positioning more intelligent. Without detailed knowledge of font sizes, etc, this is code wouldn't work. So, unless you would like to export text as curves rather than text, it's probably not that feasible currently. If curves are ok, it's probably fairly easy. One way to proceed would be to try to abstract as much drawing logic as possible to into a higher level paint device. Perhaps extending the QPainter device with text commands would work, or making a new paint device at a higher level than Qt.
