Isn't the standard solution to use a queue for updating the GUI? At least I didn't have any problems at all with my one TKinter app, I think the method is described in the Python Cookbook. Stefan Krah

The 2nd edition, Recipe 11.9 Combining GUIs and Asynchronous I/O with Threads gives an example that processes items in the queue 5 times a second. I can understand the desire to avoid the put and get overhead and the poll wait by calling a gui method directly. This works when one uses tcl/tk compiled with thread support and avoids inter-thread deadlocks. See my answer to Chris A. for details. -- Terry Jan Reedy
