[Tutor] wx.CallLater doesn't work in subprocess

[Katsuyoshi Takahashi]

Hello everyone,

I'm trying make a the Simple Game program with GUI using wxPython. I 
used multiprocessing library in Python version 3.4. But, wx.CallLater 
Class doesn't work in subprocess.

classLOCthink(object):
     def__init__(self):
         super(LOCthink,self).__init__()

     defengine_think(self,queue_send,queue_command):

         importwx

         self.queue_command = queue_command
         self.queue_send = queue_send
         self.coord =0

         self.command = wx.CallLater(100,self.command_process)

     defcommand_process(self):
         fordummyinrange(10):
             self.queue_send.put_nowait(str(dummy))
         self.command.Start(100)

When I start Process at 'engine_think' function, then error occur with 
this message,

     self.command = wx.CallLater(100, self.command_process)
AttributeError: 'function' object has no attribute 'command_process'

In main process, I use same wx.CallAfter class and it works.
Is wx.CallLater not be able to use in subprocess? or I write wrong code 
in this class?
