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 its targeted version of the FOX library, and as long as FOX's API is still changing there's a good chance that the "latest" version of FXPy will not be compatible with the "latest" version of FOX. For this reason, you should pay close attention to the FXPy version number; it should match the FOX library version to which you're linking. Once FOX 1.0 is officially released (and the API is presumably frozen) this instability should be less of an issue.
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.
