there is no built-in support.

However:

SVG is XML, so you ca use one of the XML packages to read/write it.

wx.GraphicsContext uses a similardrawing model, so you should be able to do the drawing pretty easily. In fact, a couple years back someone write a minimal SVG renderer in wxPython -- some googling should find it.

You might also want to take a look at Cairo -- you can render to a wxWindow with Cairo, and it has some advantages over wxGraphicsContext.

You may want to take a look at FloatCanvas2:

http://svn.wxwidgets.org/viewvc/wx/wxPython/3rdParty/branches/FloatCanvas/SOC2008_FloatCanvas/floatcanvas2/

It was developed as a Google Summer of Code project, and is not quite complete, but has a lot of nifty stuff in it.

You could also look at FloatCanvas in wx.lib.floatcanvas -- it used wx.DCs primarily, so does not support many of the SVG features (alpha blending, proper spline paths, etc. But it could be adapted to use GCs (or Cairo) and you can get ideas from it as well.

Making a full-featured editor is still a massive project, however.

Good luck!

I want minimal… I have done over Web but now I want a desktop client.
