[python-win32] simulate DoEvents by python/wxpython

[James Hu]

Thanks, say there are two threads, one is wxGUI, another is camera,
which will send lots of data (1280X1280) to wxGUI, or notify wxGUI by
event to retrieve it after a frame of image is ready. If synchronized
well, this approach should work as well.

Threads all share the same address space.  There is no need to 
"exchange" data at all.

A separate thread is almost certainly the right way to do what you ask.

You can use Python Queues to send messages between the threads, to 
signal when an image is available, or to signal that a worker thread 
should exit.
