[wxPython-users] Accepting files for Drag and drop on OS-X

Hi Kevin,

I'll try to add it today.

I just figured that out myself, when I noticed that I had argv emulation 
turned on.

However, it would be nice have one point of entry, so I tried turning 
argv emulation off, and then did get a MacOpenFile event, but with:

"-psn_0_66322433"

instead of a file name. Curious.

So I guess parsing sys.argv is the way to go. I suppose that's fine, as 
it will work for command line usage as well.

The next step is to figure out how to catch it when a file is dropped in 
the app Frame, in addition to dropping on the icon in the Finder or Doc.

Thanks,
  -Chris
