+ @par wxWEB_VIEW_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 wxWEB_VIEW_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_COMMAND_WEB_VIEW_LOADED notifies
+ when the page or a sub-frame has finished loading and
+ @c wxEVT_COMMAND_WEB_VIEW_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
