precision is platform-dependent, but in general will not be better than 1ms nor
worse than 1s.

+There are three different ways to use this class:
\begin{enumerate}
\item You may derive a new class from wxTimer and override the
\helpref{Notify}{wxtimernotify} member to perform the required action.
\item Or you may redirect the notifications to any
-\helpref{wxEvtHandler}{wxevthandler} derived object by using the non default
-constructor or \helpref{SetOwner}{wxtimersetowner}. Then use {\tt EVT\_TIMER}
+\helpref{wxEvtHandler}{wxevthandler} derived object by using the non-default
+constructor or \helpref{SetOwner}{wxtimersetowner}. Then use the {\tt EVT\_TIMER}
macro to connect it to the event handler which will receive
\helpref{wxTimerEvent}{wxtimerevent} notifications.
+\item Or you may use a derived class and the {\tt EVT\_TIMER}
+macro to connect it to an event handler defined in the derived class.
+If the default constructor is used, the timer object will be its
+own owner object, since it is derived from wxEvtHandler.
\end{enumerate}
In any case, you must start the timer with \helpref{Start}{wxtimerstart}
after constructing it before it actually starts sending notifications. It can
be stopped later with \helpref{Stop}{wxtimerstop}.
+{\bf Note:} A timer can only be used from the main thread.
