First, a few general comments:
It goes without saying that any bugs in the FOX library will be exposed in FXPy as well.
FXPy is pretty highly coupled with FOX, and so you need to be careful about which versions of FXPy and FOX you're using together. Any of the FXPy-1.0.x releases should work with any of the fox-1.0.x releases, since the FOX 1.0 API is stable. However, if you need to use FXPy with a development version of FOX, be sure that the version numbers for both are compatible.
All of the test programs run, but some of them don't quite work properly. For example, the image.py test shows the wrong images. So sue me, I'm working on it :)
The following FOX features (including some class member functions) are currently not supported by FXPy. They will probably be supported in a future release of FXPy unless there is some overwhelming technical reason not to do so.
FXVec, FXDVec, FXRange, FXHMat, FXDHMat, FXHVec, FXDHVec, FXQuat and FXDQuat are not implemented.
Although the FXStream and FXFileStream classes are exposed to Python to a limited degree, you can't really mix and match Python serialization with FOX's serialization. For an example of how you can use FOX stream objects from Python, see the imageviewer.py test program, where we use an FXFileStream object to load and save the image data.
For FXGLViewer, the getZSortFunc(), and setZSortFunc() functions are not yet implemented.
For FXGLTriangleMesh, the setVertexBuffer(), setColorBuffer(), setNormalBuffer(), setTextureCoordBuffer(), getVertexBuffer(), getColorBuffer(), getNormalBuffer() and getTextureCoordBuffer() functions need to be fixed.
The static member function FXFont.listFonts() is missing.
