+
+ A navigation event holds information about events associated with
+ wxWebView objects.
+
+ @beginEventEmissionTable{wxWebNavigationEvent}
+ @event{EVT_WEB_VIEW_NAVIGATING(id, func)}
+ Process a @c wxEVT_COMMAND_WEB_VIEW_NAVIGATING event, generated before trying
+ to get a resource. This event may be vetoed to prevent navigating to this
+ resource. Note that if the displayed HTML document has several frames, one
+ such event will be generated per frame.
+ @event{EVT_WEB_VIEW_NAVIGATED(id, func)}
+ Process a @c wxEVT_COMMAND_WEB_VIEW_NAVIGATED event generated after it was
+ confirmed that a resource would be requested. This event may not be vetoed.
+ Note that if the displayed HTML document has several frames, one such event
+ will be generated per frame.
+ @event{EVT_WEB_VIEW_LOADED(id, func)}
+ Process a @c wxEVT_COMMAND_WEB_VIEW_LOADED event generated when the document
+ is fully loaded and displayed.
+ @event{EVT_WEB_VIEW_ERRROR(id, func)}
+ Process a @c wxEVT_COMMAND_WEB_VIEW_ERROR event generated when a navigation
+ error occurs.
+ The integer associated with this event will be a wxWebNavigationError item.
+ The string associated with this event may contain a backend-specific more
+ precise error message/code.
+ @event{EVT_WEB_VIEW_NEWWINDOW(id, func)}
+ Process a @c wxEVT_COMMAND_WEB_VIEW_NEWWINDOW event, generated when a new
+ window is created. This event may be vetoed to prevent a new window showing,
+ for example if you want to open the url in the existing window or a new tab.
