Detailed Description

A navigation event holds information about events associated with wxWebView objects.

Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxWebViewEvent& event)

Event macros for events emitted by this class:

EVT_WEBVIEW_NAVIGATING(id, func):
Process a wxEVT_WEBVIEW_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.
EVT_WEBVIEW_NAVIGATED(id, func):
Process a wxEVT_WEBVIEW_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.
EVT_WEBVIEW_LOADED(id, func):
Process a wxEVT_WEBVIEW_LOADED event generated when the document is fully loaded and displayed. Note that if the displayed HTML document has several frames, one such event will be generated per frame.
EVT_WEBVIEW_ERROR(id, func):
Process a wxEVT_WEBVIEW_ERROR event generated when a navigation error occurs. The integer associated with this event will be a wxWebViewNavigationError item. The string associated with this event may contain a backend-specific more precise error message/code.
EVT_WEBVIEW_NEWWINDOW(id, func):
Process a wxEVT_WEBVIEW_NEWWINDOW event, generated when a new window is created. You must handle this event if you want anything to happen, for example to load the page in a new window or tab.
EVT_WEBVIEW_TITLE_CHANGED(id, func):
Process a wxEVT_WEBVIEW_TITLE_CHANGED event, generated when the page title changes. Use GetString to get the title.

Public Member Functions
	wxWebViewEvent ()

	wxWebViewEvent (wxEventType type, int id, const wxString href, const wxString target)

const wxString &	GetTarget () const
	Get the name of the target frame which the url of this event has been or will be loaded into.

const wxString &	GetURL () const
	Get the URL being visited.

Public Member Functions inherited from wxNotifyEvent
	wxNotifyEvent (wxEventType eventType=wxEVT_NULL, int id=0)
	Constructor (used internally by wxWidgets only).

void	Allow ()
	This is the opposite of Veto(): it explicitly allows the event to be processed.

bool	IsAllowed () const
	Returns true if the change is allowed (Veto() hasn't been called) or false otherwise (if it was).

void	Veto ()
	Prevents the change announced by this event from happening.

Public Member Functions inherited from wxCommandEvent
	wxCommandEvent (wxEventType commandEventType=wxEVT_NULL, int id=0)
	Constructor.

void *	GetClientData () const
	Returns client data pointer for a listbox or choice selection event (not valid for a deselection).

wxClientData *	GetClientObject () const
	Returns client object pointer for a listbox or choice selection event (not valid for a deselection).

long	GetExtraLong () const
	Returns extra information dependent on the event objects type.

int	GetInt () const
	Returns the integer identifier corresponding to a listbox, choice or radiobox selection (only if the event was a selection, not a deselection), or a boolean value representing the value of a checkbox.

int	GetSelection () const
	Returns item index for a listbox or choice selection event (not valid for a deselection).

wxString	GetString () const
	Returns item string for a listbox or choice selection event.

bool	IsChecked () const
	This method can be used with checkbox and menu events: for the checkboxes, the method returns true for a selection event and false for a deselection one.

bool	IsSelection () const
	For a listbox or similar event, returns true if it is a selection, false if it is a deselection.

void	SetClientData (void *clientData)
	Sets the client data for this event.

void	SetClientObject (wxClientData *clientObject)
	Sets the client object for this event.

void	SetExtraLong (long extraLong)
	Sets the m_extraLong member.

void	SetInt (int intCommand)
	Sets the m_commandInt member.

void	SetString (const wxString &string)
	Sets the m_commandString member.

Public Member Functions inherited from wxEvent
	wxEvent (int id=0, wxEventType eventType=wxEVT_NULL)
	Constructor.

virtual wxEvent *	Clone () const =0
	Returns a copy of the event.

wxObject *	GetEventObject () const
	Returns the object (usually a window) associated with the event, if any.

wxEventType	GetEventType () const
	Returns the identifier of the given event type, such as `wxEVT_BUTTON`.

virtual wxEventCategory	GetEventCategory () const
	Returns a generic category for this event.

int	GetId () const
	Returns the identifier associated with this event, such as a button command id.

wxObject *	GetEventUserData () const
	Return the user data associated with a dynamically connected event handler.

bool	GetSkipped () const
	Returns true if the event handler should be skipped, false otherwise.

long	GetTimestamp () const
	Gets the timestamp for the event.

bool	IsCommandEvent () const
	Returns true if the event is or is derived from wxCommandEvent else it returns false.

void	ResumePropagation (int propagationLevel)
	Sets the propagation level to the given value (for example returned from an earlier call to wxEvent::StopPropagation).

void	SetEventObject (wxObject *object)
	Sets the originating object.

void	SetEventType (wxEventType type)
	Sets the event type.

void	SetId (int id)
	Sets the identifier associated with this event, such as a button command id.

void	SetTimestamp (long timeStamp=0)
	Sets the timestamp for the event.

bool	ShouldPropagate () const
	Test if this event should be propagated or not, i.e. if the propagation level is currently greater than 0.

void	Skip (bool skip=true)
	This method can be used inside an event handler to control whether further event handlers bound to this event will be called after the current one returns.

int	StopPropagation ()
	Stop the event from propagating to its parent window.

Public Member Functions inherited from wxObject
	wxObject ()
	Default ctor; initializes to NULL the internal reference data.

	wxObject (const wxObject &other)

virtual wxClassInfo *	GetClassInfo () const
	This virtual function is redefined for every class that requires run-time type information, when using the wxDECLARE_CLASS macro (or similar).

bool	IsKindOf (const wxClassInfo *info) const
	Determines whether this class is a subclass of (or the same class as) the given class.

bool	IsSameAs (const wxObject &obj) const
	Returns true if this object has the same data pointer as obj.

void	Ref (const wxObject &clone)
	Makes this object refer to the data in clone.

void	SetRefData (wxObjectRefData *data)
	Sets the wxObject::m_refData pointer.

void	UnRef ()
	Decrements the reference count in the associated data, and if it is zero, deletes the data.

void	UnShare ()
	This is the same of AllocExclusive() but this method is public.

void	operator delete (void *buf)
	The delete operator is defined for debugging versions of the library only, when the identifier `WXDEBUG` is defined.

void *	operator new (size_t size, const wxString &filename=NULL, int lineNum=0)
	The new operator is defined for debugging versions of the library only, when the identifier `WXDEBUG` is defined.
