 Connects the given function dynamically with the event handler, id and event type. This
 is an alternative to the use of static event tables. See the 'event' or the old 'dynamic' sample for usage.

-\docparam{id}{The identifier (or first of the identifier range) to be associated with the event handler function.}
+\docparam{id}{The identifier (or first of the identifier range) to be
+associated with the event handler function. For the version not taking this
+argument, it defaults to \texttt{wxID\_ANY}.}

 \docparam{eventType}{The event type to be associated with this event handler.}

+\docparam{function}{The event handler function. Note that this function should
+be explicitly converted to the correct type which can be done using a macro
+called \texttt{wxFooEventHandler} for the handler for any \texttt{wxFooEvent}.}
