   3 The wxStopWatch class allow you to measure time intervals. For example, you may
   4 use it to measure the time elapsed by some function:
   5
   6 \begin{verbatim}
   7     wxStopWatch sw;
   8     CallLongRunningFunction();
   9     wxLogMessage("The long running function took %ldms to execute",
  10                  sw.Time());
  11     sw.Pause();
  12     ... stopwatch is stopped now ...
  13     sw.Resume();
  14     CallLongRunningFunction();
  15     wxLogMessage("And calling it twice took $ldms in all", sw.Time());
  16 \end{verbatim}

  28 \membersection{wxStopWatch::wxStopWatch}
  29
  30 \func{}{wxStopWatch}{\void}
  31
  32 Constructor. This starts the stop watch.
  33
  34 \membersection{wxStopWatch::Pause}\label{wxstopwatchpause}
  35
  36 \func{void}{Pause}{\void}
  37
  38 Pauses the stop watch. Call \helpref{wxStopWatch::Resume}{wxstopwatchresume} to resume
  39 time measuring again.
  40
  41 If this method is called several times, {\tt Resume()} must be called the same
  42 number of times to really resume the stop watch. You may, however, call
  43 \helpref{Start}{wxstopwatchstart} to resume it unconditionally.
  44
  45 \membersection{wxStopWatch::Resume}\label{wxstopwatchresume}
  46
  47 \func{void}{Resume}{\void}
  48
  49 Resumes the stop watch which had been paused with
  50 \helpref{wxStopWatch::Pause}{wxstopwatchpause}.
  51
  52 \membersection{wxStopWatch::Start}\label{wxstopwatchstart}
  53
  54 \func{void}{Start}{\param{long}{ milliseconds = 0}}
  55
  56 (Re)starts the stop watch with a given initial value.
  57
  58 \membersection{wxStopWatch::Time}
  59
  60 \constfunc{long}{Time}{\void}\label{wxstopwatchtime}
  61
  62 Returns the time in milliseconds since the start (or restart) or the last call of
  63 \helpref{wxStopWatch::Pause}{wxstopwatchpause}.
