[wxPython-mac] Problems with wx.Process & wx.Execute

[John Jackson]

Yes, I was half-way there by remembering to use the full path to  
python on my system.

Here's a patch for the "Process" demo: replace the "OnIdle" method with

     def OnIdle(self, evt):
         if self.process is not None:
             stream = self.process.GetInputStream()

             if stream.CanRead():
                 text = stream.read()
                 self.out.AppendText(text)

             stream = self.process.GetErrorStream()

             if stream.CanRead():
                 text = stream.read()
                 self.out.AppendText("Errors:\n%s" % text)

This way, an error like mine will show up.

Also, perhaps a test should be added to "OnSendText " for the output  
stream, because I did somehow manage to get a condition where that  
failed (stream was None):

     def OnSendText(self, evt):
         text = self.inp.GetValue()
         self.inp.SetValue('')
         self.log.write('OnSendText: "%s"\n' % text)
#        self.process.GetOutputStream().write(text + '\n')
         stream = self.process.GetOutputStream()
         if stream:
             stream.write(text + '\n')
         self.inp.SetFocus()

I had filed a bug report (#1912883); I've updated it, and asked that  
the debug warnings get turned off, as they are just confusing the  
issue...

I've gotten further -- I can start and stop the server --, but am  
still having a problem with
1. the initial output from the process getting lost (at one I _was_  
getting it, but not anymore!)
2. wx.EVT_END_PROCESS never happening and associated method never  
being called.
