\wxheading{Event handling}

To process input from a wxHtmlCellEvent, use one of these event handler macros to
direct input to member function that take a \helpref{wxHtmlCellEvent}{wxhtmlcellevent} argument:

\twocolwidtha{7cm}
\begin{twocollist}
\twocolitem{{\bf EVT\_HTML\_CELL\_HOVER(id, func)}}{User moved the mouse over a \helpref{wxHtmlCell}{wxhtmlcell}.}
\twocolitem{{\bf EVT\_HTML\_CELL\_CLICKED(id, func)}}{User clicked on a \helpref{wxHtmlCell}{wxhtmlcell}. When handling this event, remember to use \helpref{wxHtmlCell::SetLinkClicked(true)}{wxhtmlcelleventsetlinkclicked} if the cell contains a link.}

\membersection{wxHtmlCellEvent::wxHtmlCellEvent}\label{wxhtmlcelleventctor}

\func{}{wxHtmlCellEvent}{\param{wxEventType}{ commandType}, \param{int}{ id}, \param{wxHtmlCell *}{ cell}, \param{const wxPoint \&}{ point}}

The constructor is not normally used by the user code.


\membersection{wxHtmlCellEvent::GetCell}\label{wxhtmlcelleventgetcell}

\constfunc{wxHtmlCell *}{GetCell}{\void}

\false otherwise (which is the default). With this function the event handler can return info to the
wxHtmlWindow which sent the event.


\membersection{wxHtmlCellEvent::GetLinkClicked}\label{wxhtmlcelleventgetlinkclicked}

\constfunc{bool}{GetLinkClicked}{\void}

Returns \true if \helpref{SetLinkClicked(true)}{wxhtmlcelleventsetlinkclicked} has previously been called;
