Python - 如何在必要时杀死计时器而不是让它永远运行？

Question

How do i kill this timer, once it was executed/started ?

def my_timer(*args):
    return True# do ur work here, but not for long

gtk.timeout_add(1000, my_timer) # call every min

Answer 1

Two options:

• If you know inside my_timer() function that it should not be called again, just return False
• Alternatively, store the event id that timeout_add() returns and do a g_source_remove(event_id) when it's no longer needed

Also, the "call every minute" comment is wrong: the handle will be called every second.

Suggestion: use timeout_add_seconds() if you do not need sub-second accuracy. It allows glib to optimize things and is better for power management.

Answer 2

def my_timer(*args):
    return True# do ur work here, but not for long

t =gtk.timeout_add(1000, my_timer) # call every min
time.sleep(5)
gtk.timeout_remove(t)              # kill the timer
