\membersection{wxEvent::wxEvent}\label{wxeventctor}
\func{}{wxEvent}{\param{int }{id = 0}, \param{wxEventType }{eventType = {\tt wxEVT\_NULL}}}
Constructor. Should not need to be used directly by an application.
-\membersection{wxEvent::m\_eventObject}\label{wxeventmeventobject}
-
-\member{wxObject*}{m\_eventObject}
-
-The object (usually a window) that the event was generated from,
-or should be sent to.
-
-\membersection{wxEvent::m\_eventType}\label{wxeventmeventtype}
-
-\member{WXTYPE}{m\_eventType}
-
-The type of the event, such as wxEVENT\_TYPE\_BUTTON\_COMMAND.
-
-\membersection{wxEvent::m\_id}\label{wxeventmid}
-
-\member{int}{m\_id}
-
-Identifier for the window.
\membersection{wxEvent::m\_propagationLevel}\label{wxeventmpropagationlevel}
+
\member{int}{m\_propagationLevel}
Indicates how many levels the event can propagate. This member is protected and
the given number of times. E.g. the propagation level may be set to $1$ to
propagate the event to its parent only, but not to its grandparent.
-\membersection{wxEvent::m\_skipped}\label{wxeventmskipped}
-
-\member{bool}{m\_skipped}
-
-Set to true by {\bf Skip} if this event should be skipped.
-
-\membersection{wxEvent::m\_timeStamp}\label{wxeventmtimestamp}
-
-\member{long}{m\_timeStamp}
-
-Timestamp for this event.
\membersection{wxEvent::Clone}\label{wxeventclone}
wxEvent *Clone(void) const { return new MyEvent(*this); }

\func{wxObject*}{GetEventObject}{\void}

+
\membersection{wxEvent::GetEventType}\label{wxeventgeteventtype}
-\func{WXTYPE}{GetEventType}{\void}
+\func{wxEventType}{GetEventType}{\void}
Returns the identifier of the given event type,
-such as wxEVENT\_TYPE\_BUTTON\_COMMAND.
+such as \texttt{wxEVT\_COMMAND\_BUTTON\_CLICKED}.
+
\membersection{wxEvent::GetId}\label{wxeventgetid}
Returns the identifier associated with this event, such as a button command id.
+
\membersection{wxEvent::GetSkipped}\label{wxeventgetskipped}
\constfunc{bool}{GetSkipped}{\void}
Returns true if the event handler should be skipped, false otherwise.
+
\membersection{wxEvent::GetTimestamp}\label{wxeventgettimestamp}
\func{long}{GetTimestamp}{\void}
-Gets the timestamp for the event.
+Gets the timestamp for the event. The timestamp is the time in milliseconds
+since some fixed moment (\emph{not} necessarily the standard Unix Epoch, so
+only differences between the timestamps and not their absolute values usually
+make sense).
+
\membersection{wxEvent::IsCommandEvent}\label{wxeventiscommandevent}
Sets the originating object.
+
\membersection{wxEvent::SetEventType}\label{wxeventseteventtype}
-\func{void}{SetEventType}{\param{WXTYPE }{typ}}
+\func{void}{SetEventType}{\param{wxEventType }{type}}
Sets the event type.
+
\membersection{wxEvent::SetId}\label{wxeventsetid}
\func{void}{SetId}{\param{int}{ id}}
Sets the identifier associated with this event, such as a button command id.
+
\membersection{wxEvent::SetTimestamp}\label{wxeventsettimestamp}
\func{void}{SetTimestamp}{\param{long }{timeStamp}}
Sets the timestamp for the event.
-Sets the originating object.
\membersection{wxEvent::ShouldPropagate}\label{wxeventshouldpropagate}
Test if this event should be propagated or not, i.e. if the propagation level
is currently greater than $0$.
+
\membersection{wxEvent::Skip}\label{wxeventskip}
\func{void}{Skip}{\param{bool}{ skip = true}}
-Called by an event handler, it controls whether additional event
-handlers bound to this event will be called after the current event
-handler returns. Skip(false) (the default setting) will prevent
-additional event handlers from being called and control will be
-returned to the sender of the event immediately after the current
-handler has finished. Skip(True) will cause the event processing
-system to continue searching for a handler function for this event.
+This method can be called by an event handler and controls whether additional
+event handlers bound to this event will be called after the current event
+handler returns. The default behavior is equivalent to calling Skip(false)
+(which is, hence, usually unnecessary) and will prevent additional event
+handlers from being called and control will be returned to the sender of the
+event immediately after the current handler has finished. If Skip(true) is
+called, the event processing system continues searching for a handler
+function for this event as if the current handler didn't exist.
+
+In general, it is recommended to skip all non-command events to allow the
+default handling to take place. The command events are, however, normally not
+skipped as usually a single command such as a button click or menu item
+selection must only be processed by one handler.
