 \item You may derive a new class from wxTimer and override the

 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

 \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.
