I have used QGIS from an OSGEO build and I find the refresh rates for
layers to be very slow. Is there anything that I can do to overcome this
problem. I am willing to compile myself if there anything I can do to
help it.

Dear QGIS Developer Family:
I
am looking for any documentation/instructions about how to make a C++
DLL interact with QGIS as a plugin. I would not mind using either
completely in c++ through perhaps QT or with a Python front end inside
QGIS. I have some experience making Python plugins, now
I am wondering which APIdocumentation is applicable for Python functions for
Version 1.6 Copiapo release.
For example, I was using QGSGeometry and according to the documentation it
takes a point and returns a double and another argument that receives a vertex
(closest) on the line segment

That was a wonderful video, Nathan. Thanks for all the work!

I know there are not many windows users here, but is it related to Threading or

The code is pasted below, the setSubsetString passes and yet the selected
