Nino/Dražen, Thanks for the pointer to HaosBuilder.
I checked it out and it is a good introduction to using Mapnik with wxPython and has allowed me to quickly test my layers for rendering speed.

I've used it, and it simple while complete enough to be useful. Nino On Mon, Sep 27, 2010 at 10:02 AM, Angus Dickey <[email protected]> wrote: Noli, Thanks for the info. I saw that sqlite/spatialite was supported by Mapnik but I have to admit the "WARNING: highly uber experimental !" at the top of the page put me off a bit. I will definitely try if out though; is it more stable than the docs let on? You are right about the mapcanvas, having that would be really convenient. In wxPython it looks like I will have to build something that would allow me to display the map generated by Mapnik with basic /zoom/pan/measure/query tool functionality from scratch. Drawing the map is pretty easy I think. I can just draw the Mapnik produced bitmap right on a wx.Panel, the trick will be creating some basic tools and having them support geographic & projected coordinate systems. Thanks again for your help, I will check out the quantumnik and look for that sample using pyQT without the QGIS mapcanvas.
