What you most likely want to do is run the win32gui call inside an
infinite loop. Something along these lines:
# untested code
import time
while True:
winTitle = GetWindowText(GetForegroundWindow())
if winTitle == 'some string':
# do something
time.sleep(1) # nap for a second
This will check once a second to see what window you have up. You'll
probably want to set some kind of sentinel value when it does
something to the current window so it doesn't repeatedly do that
something each second. Thus, the if-then logic will need to be more
complex, but this should get you going.
