@class wxStopWatch
The wxStopWatch class allow you to measure time intervals.
For example, you may use it to measure the time elapsed by some function:
@code
wxStopWatch sw;
CallLongRunningFunction();
wxLogMessage("The long running function took %ldms to execute",
sw.Time());
sw.Pause();
... stopwatch is stopped now ...
sw.Resume();
CallLongRunningFunction();
wxLogMessage("And calling it twice took $ldms in all", sw.Time());
@endcode
@library{wxbase}
@category{misc}
@see wxTimer
