I also need to block events in my wxPython app, though the time duration is
very short. I have a separate thread that sends notification of gui events
to a server, and waits for a response. I do not want the user to do anything
until the response is received.
I use threading.Event() for this -
import threading
event_waiting = threading.Event()
event_waiting.set() # set event to True
In the gui thread, when I want to block, I have this -
event_waiting.clear() # set event to False
event_waiting.wait() # block until event becomes True
In the worker thread, when the response has been received and acted upon, I
have -
event_waiting.set() # set event to True, which unblocks the gui thread
