/**
    @class wxWebView

    This control may be used to render web (HTML / CSS / javascript) documents.
    It is designed to allow the creation of multiple backends for each port,
    although currently just one is available. It differs from wxHtmlWindow in
    that each backend is actually a full rendering engine, Trident on MSW and
    Webkit on OSX and GTK. This allows the correct viewing complex pages with
    javascript and css.

    @section descriptions Backend Descriptions

    @par wxWEBVIEW_BACKEND_IE (MSW)

    The IE backend uses Microsoft's Trident rendering engine, specifically the
    version used by the locally installed copy of Internet Explorer. As such it
    is only available for the MSW port. By default recent versions of the
    <a href="http://msdn.microsoft.com/en-us/library/aa752085%28v=VS.85%29.aspx">WebBrowser</a>
    control, which this backend uses, emulate Internet Explorer 7. This can be
    changed with a registry setting, see
    <a href="http://msdn.microsoft.com/en-us/library/ee330730%28v=vs.85%29.aspx#browser_emulation">
    this</a> article for more information. This backend has full support for
    custom schemes and virtual file systems.

    @par wxWEBVIEW_WEBKIT (GTK)

    Under GTK the WebKit backend uses
    <a href="http://webkitgtk.org/">WebKitGTK+</a>. The current minimum version
    required is 1.3.1 which ships by default with Ubuntu Natty and Debian
    Wheezy and has the package name libwebkitgtk-dev. Custom schemes and
    virtual files systems are supported under this backend, however embedded
    resources such as images and stylesheets are currently loaded using the
    data:// scheme.

    @par wxWEBVIEW_WEBKIT (OSX)

    The OSX WebKit backend uses Apple's
    <a href="http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/WebKit/Classes/WebView_Class/Reference/Reference.html#//apple_ref/doc/uid/20001903">WebView</a>
    class. This backend has full support for custom schemes and virtual file
    systems.

    @section async Asynchronous Notifications

    Many of the methods in wxWebView are asynchronous, i.e. they return
    immediately and perform their work in the background. This includes
    functions such as LoadURL() and Reload(). To receive notification of the
    progress and completion of these functions you need to handle the events
    that are provided. Specifically @c wxEVT_WEBVIEW_LOADED notifies
    when the page or a sub-frame has finished loading and
    @c wxEVT_WEBVIEW_ERROR notifies that an error has occurred.

    @section vfs Virtual File Systems and Custom Schemes

    wxWebView supports the registering of custom scheme handlers, for example
    @c file or @c http. To do this create a new class which inherits from
    wxWebViewHandler, where wxWebHandler::GetFile() returns a pointer to a
    wxFSFile which represents the given url. You can then register your handler
    with RegisterHandler() it will be called for all pages and resources.

    wxWebViewFSHandler is provided to access the virtual file system encapsulated by
    wxFileSystem. The wxMemoryFSHandler documentation gives an example of how this
    may be used.

    wxWebViewArchiveHandler is provided to allow the navigation of pages inside a zip
    archive. It supports paths of the form:
    @c scheme:///C:/example/docs.zip;protocol=zip/main.htm

    @beginEventEmissionTable{wxWebViewEvent}
    @event{EVT_WEBVIEW_NAVIGATING(id, func)}
       Process a @c 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.
    @event{EVT_WEBVIEW_NAVIGATED(id, func)}
       Process a @c 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.
    @event{EVT_WEBVIEW_LOADED(id, func)}
       Process a @c 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.
    @event{EVT_WEBVIEW_ERROR(id, func)}
       Process a @c wxEVT_WEBVIEW_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_WEBVIEW_NEWWINDOW(id, func)}
       Process a @c 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.
    @event{EVT_WEBVIEW_TITLE_CHANGED(id, func)}
       Process a @c wxEVT_WEBVIEW_TITLE_CHANGED event, generated when
       the page title changes. Use GetString to get the title.

    @class wxWebViewEvent

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

    @beginEventEmissionTable{wxWebViewEvent}
    @event{EVT_WEBVIEW_NAVIGATING(id, func)}
       Process a @c 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.
    @event{EVT_WEBVIEW_NAVIGATED(id, func)}
       Process a @c 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.
    @event{EVT_WEBVIEW_LOADED(id, func)}
       Process a @c 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.
    @event{EVT_WEBVIEW_ERROR(id, func)}
       Process a @c 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.
    @event{EVT_WEBVIEW_NEWWINDOW(id, func)}
       Process a @c 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.
    @event{EVT_WEBVIEW_TITLE_CHANGED(id, func)}
       Process a @c wxEVT_WEBVIEW_TITLE_CHANGED event, generated when
       the page title changes. Use GetString to get the title.
