+\func{virtual wxHtmlOpeningStatus}{OnOpeningURL}{\param{wxHtmlURLType }{type},\param{const wxString\& }{url}, \param{wxString *}{redirect}}
+
+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
+behaviour is to always return {\tt wxHTML\_OPEN}.
