-\func{virtual void}{OnLinkClicked}{\param{wxHtmlLinkInfo* }{link}}
+\func{virtual void}{OnLinkClicked}{\param{const wxHtmlLinkInfo\& }{link}}
Called when user clicks on hypertext link. Default behaviour is to call

+
+Called when an URL is being opened (either when the user clicks on a link or
+an image is loaded). The URL will be opened only if OnOpeningURL returns
+{\tt wxHTML\_OPEN}. This method is called by
+\helpref{wxHtmlParser::OpenURL}{wxhtmlparseropenurl}.
+You can override OnOpeningURL to selectively block some
+URLs (e.g. for security reasons) or to redirect them elsewhere. Default
