This error sounds like wx is using the *wrong* buffer protocol. Don't use bf_getcharbuffer as it is of uncertain utility. It is slated for removal from Python 3000. It was meant to be used as a way to determine buffers that were supposed to contain characters (not arbitrary data). Just use bf_getreadbuffer and bf_getwritebuffer from tp_as_buffer. More support for the buffer protocol all the way around is a good idea. NumPy has always supported it very well (just make sure to use it correctly). FYI, I'm going to write a PEP to get the array protocol placed as an add-on to the buffer protocol for Python 2.6 -Travis ------------------------------------------------------------------------- Using Tomcat but need to do more?
