For more information about events, see the Event handling overview . .SH "PARENTS" wxObject .SH "INCLUDE FILES" wx/event.h .SH MEMBERS .SS wxEvent (int id = 0wxEventType eventType = wxEVT_NULL) Constructor. Should not need to be used directly by an application. .SS virtual wxEvent* Clone () Returns a copy of the event. Any event that is posted to the wxWidgets event system for later action (via wxEvtHandler::AddPendingEvent or wxPostEvent ) must implement this method. All wxWidgets events fully implement this method, but any derived events implemented by the user should also implement this method just in case they (or some event derived from them) are ever posted. All wxWidgets events implement a copy constructor, so the easiest way of implementing the Clone function is to implement a copy constructor for a new event (call it MyEvent) and then define the Clone function like this: wxEvent *Clone(void) const { return new MyEvent(*this); } .SS wxObject* GetEventObject () Returns the object (usually a window) associated with the event, if any. .SS WXTYPE GetEventType () Returns the identifier of the given event type, such as wxEVENT_TYPE_BUTTON_COMMAND. .SS int GetId () Returns the identifier associated with this event, such as a button command id. .SS bool GetSkipped () Returns true if the event handler should be skipped, false otherwise. .SS long GetTimestamp () Gets the timestamp for the event. .SS bool IsCommandEvent () Returns true if the event is or is derived from wxCommandEvent else it returns false. Note: Exists only for optimization purposes. .SS void ResumePropagation (int propagationLevel) Sets the propagation level to the given value (for example returned from an earlier call to StopPropagation ). .SS void SetEventObject (wxObject* object) Sets the originating object. .SS void SetEventType (WXTYPE typ) Sets the event type. .SS void SetId (int id) Sets the identifier associated with this event, such as a button command id. .SS void SetTimestamp (long timeStamp) Sets the timestamp for the event. .SS bool ShouldPropagate () Test if this event should be propagated or not, i.e. if the propagation level is currently greater than 0. .SS void Skip (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 behavior) 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. .SS int StopPropagation () Stop the event from propagating to its parent window. Returns the old propagation level value which may be later passed to ResumePropagation to allow propagating the event again. .SH "SEE ALSO" wxObject wxCommandEvent , wxMouseEvent .SH "AUTHORS" Documentation content by Julian Smart, Robert Roebling, Vadim Zeitlin, Robin Dunn, et al Conversion to manpage format by Arnout Engelen (http://bzzt.net), bugreports welcome.
