[vtkusers] Cocoa, Python, VTK and wx embedded window problems

[Dan White]

Dear John,

look at the source code from bioimagexd
www.bioimagexd.net

and you can see how we do it (no magic involved i think,
Kalle, Lassi, any hints?)

we are using python, wxPython, python wrapped VTK (Carbon)
works great for us, with mouse interactions etc. in the display window.
Maybe there are some OSX specific hacks...

you can not really use cocoa yet with wxPython, because the
Cocoa port of wxWidgets (wxCocoa) is not mature enough...
its not release in the binary release of wxPython i think.

... i wish it was because if it was we could make a 64 bit version of  
BioImageXD for OSX.
Carbon GUI are limited to 32 bit, and Carbon will be depreciated some  
time....

I'd like to get to know someone who has time an interest to work on  
the wxCocoa
port of wxWidgets.... there are several projects that would benefit  
from that...
