wx.StopWatch¶The wx.StopWatch class allow you to measure time intervals.
For example, you may use it to measure the time elapsed by some function:
sw = wx.StopWatch()
CallLongRunningFunction()
wx.LogMessage("The long running function took %dms to execute", sw.Time())
sw.Pause()
# stopwatch is stopped now ...
sw.Resume()
CallLongRunningFunction()
wx.LogMessage("And calling it twice took %dms in all", sw.Time())
Since wxWidgets 2.9.3 this class uses QueryPerformanceCounter() function under MSW to measure the elapsed time. It provides higher precision than the usual timer functions but can suffer from bugs in its implementation in some Windows XP versions. If you encounter such problems, installing a Microsoft hot fix from http://support.microsoft.com/?id=896256 could be necessary.

Class API¶
wx.StopWatch(object)¶Possible constructors:
StopWatch()
The StopWatch class allow you to measure time intervals.
__init__(self)¶Constructor.
This starts the stop watch.
Pause(self)¶Pauses the stop watch.
Call Resume to resume time measuring again.
If this method is called several times, Resume must be called the same number of times to really resume the stop watch. You may, however, call Start to resume it unconditionally.
Start(self, milliseconds=0)¶(Re)starts the stop watch with a given initial value.
The stopwatch will always be running after calling Start , even if Pause had been called before and even if it had been called multiple times.
milliseconds (long) –
Time(self)¶Returns the time in milliseconds since the start (or restart) or the last call of Pause .
