[vtkusers] Re: wxVTKRenderWindowInteractor.py fails on OSX with VTK Cocoa build

[Dan White]

Hi All,

after some further investigation,
its actually xwWidgets wherein lies the problem

the stable OSX port of xwWidgets is called wxMac,
and indeed it uses Carbon,
so i guess xwPython is using wxMac

There is a new OSX port in the wxWidgets source code already,
called xwCocoa....
however this is still missing much functionality....

So in the long run, for 64 bit VTK application using wxPython on OSX
wxPython needs to be able to use the new wxCocoa.


In the mean time, the only other option left for a 64 bit
wxPython GUI VTK application on OSX is.....

X11   (AAAAAARRRGGGHHHHH!!!!!)

... well i guess i will start work on that then!
time to break out fink....
