(such as a new control) where you define new event types, as opposed to
allowing the user to override virtual functions.
- An instance where you might actually override the ProcessEvent() function is where
- you want to direct event processing to event handlers not normally noticed by
- wxWidgets. For example, in the document/view architecture, documents and views
- are potential event handlers. When an event reaches a frame, ProcessEvent() will
- need to be called on the associated document and view in case event handler functions
- are associated with these objects. The property classes library (wxProperty) also
- overrides ProcessEvent() for similar reasons.
+ Notice that you don't usually need to override ProcessEvent() to
+ customize the event handling, overriding the specially provided
+ TryBefore() and TryAfter() functions is usually enough. For example,
+ wxMDIParentFrame may override TryBefore() to ensure that the menu
+ events are processed in the active child frame before being processed
+ in the parent frame itself.
The normal order of event table searching is as follows:
+ -# wxApp::FilterEvent() is called. If it returns anything but @c -1
+ (default) the processing stops here.
-# If the object is disabled (via a call to wxEvtHandler::SetEvtHandlerEnabled)
- the function skips to step (6).
- -# If the object is a wxWindow, ProcessEvent() is recursively called on the
- window's wxValidator. If this returns @true, the function exits.
- -# SearchEventTable() is called for this event handler. If this fails, the base
- class table is tried, and so on until no more tables exist or an appropriate
- function was found, in which case the function exits.
+ the function skips to step (7).
+ -# TryBefore() is called (this is where wxValidator are taken into
+ account for wxWindow objects). If this returns @true, the function exits.
+ -# Dynamic event table of the handlers connected using Connect() is
+ searched. If a handler is found, it is executed and the function
+ returns @true unless the handler used wxEvent::Skip() to indicate
+ that it didn't handle the event in which case the search continues.
+ -# Static events table of the handlers connected using event table
+ macros is searched for this event handler. If this fails, the base
+ class event table table is tried, and so on until no more tables
+ exist or an appropriate function was found. If a handler is found,
+ the same logic as in the previous step applies.
-# The search is applied down the entire chain of event handlers (usually the
chain has a length of one). This chain can be formed using wxEvtHandler::SetNextHandler():
@image html overview_events_chain.png
Note that in the case of wxWindow you can build a stack of event handlers
(see wxWindow::PushEventHandler() for more info).
If any of the handlers of the chain return @true, the function exits.
- -# If the object is a wxWindow and the event is a wxCommandEvent, ProcessEvent()
- is recursively applied to the parent window's event handler.
- If this returns @true, the function exits.
- -# Finally, ProcessEvent() is called on the wxApp object.
+ -# TryAfter() is called: for the wxWindow object this may propagate the
+ event to the window parent (recursively). If the event is still not
+ processed, ProcessEvent() on wxTheApp object is called as the last
+ step.
+
+ Notice that steps (2)-(6) are performed in ProcessEventHere() which is
