\wxheading{Parameters}

\docparam{cell}{The cell inside which the mouse is currently, always a simple
(i.e. non-container) cell}

\docparam{x, y}{The logical coordinates of the click point}

\membersection{wxHtmlWindow::OnLinkClicked}\label{wxhtmlwindowonlinkclicked}

\func{virtual void}{OnLinkClicked}{\param{const wxHtmlLinkInfo\& }{link}}

Called when user clicks on hypertext link. Default behaviour is to call 
\helpref{LoadPage}{wxhtmlwindowloadpage} and do nothing else.

Also see \helpref{wxHtmlLinkInfo}{wxhtmllinkinfo}.

\membersection{wxHtmlWindow::OnOpeningURL}\label{wxhtmlwindowonopeningurl}

\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}.

\wxheading{Parameters}

\docparam{type}{Indicates type of the resource. Is one of
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf wxHTML\_URL\_PAGE}}{Opening a HTML page.}
\twocolitem{{\bf wxHTML\_URL\_IMAGE}}{Opening an image.}
\twocolitem{{\bf wxHTML\_URL\_OTHER}}{Opening a resource that doesn't fall into
any other category.}
\end{twocollist}}

\docparam{url}{URL being opened.}

\docparam{redirect}{Pointer to wxString variable that must be filled with an
URL if OnOpeningURL returns {\tt wxHTML\_REDIRECT}.}

\wxheading{Return value}
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf wxHTML\_OPEN}}{Open the URL.}
\twocolitem{{\bf wxHTML\_BLOCK}}{Deny access to the URL, \helpref{wxHtmlParser::OpenURL}{wxhtmlparseropenurl} will return NULL.}
\twocolitem{{\bf wxHTML\_REDIRECT}}{Don't open {\it url}, redirect to another
URL. OnOpeningURL must fill {\it *redirect} with the new URL. OnOpeningURL will
be called again on returned URL.}

\membersection{wxHtmlWindow::ReadCustomization}\label{wxhtmlwindowreadcustomization}

\func{virtual void}{ReadCustomization}{\param{wxConfigBase }{*cfg}, \param{wxString }{path = wxEmptyString}}

This reads custom settings from wxConfig. It uses the path 'path'
if given, otherwise it saves info into currently selected path.
The values are stored in sub-path {\tt wxHtmlWindow}

Read values: all things set by SetFonts, SetBorders.

\wxheading{Parameters}

\docparam{cfg}{wxConfig from which you want to read the configuration.}

\docparam{path}{Optional path in config tree. If not given current path is used.}
