\section{\class{wxDataViewRenderer}}\label{wxdataviewrenderer}
This class is used by \helpref{wxDataViewCtrl}{wxdataviewctrl} to
render the individual cells. One instance of a renderer class is
owned by \helpref{wxDataViewColumn}{wxdataviewcolumn}. There is
a number of ready-to-use renderers provided:
\helpref{wxDataViewTextRenderer}{wxdataviewtextrenderer},
\helpref{wxDataViewToggleRenderer}{wxdataviewtogglerenderer},
\helpref{wxDataViewProgressRenderer}{wxdataviewprogressrenderer},
\helpref{wxDataViewBitmapRenderer}{wxdataviewbitmaprenderer},
\helpref{wxDataViewDateRenderer}{wxdataviewdaterenderer}.
Additionally, the user can write own renderers by deriving from
\helpref{wxDataViewCustomRenderer}{wxdataviewcustomrenderer}.
These flags control the behaviour of the renderer and they
are used for controlling in what mode the renderer shall
render its contents:
{\small
\begin{verbatim}
enum wxDataViewCellMode
{
wxDATAVIEW_CELL_INERT,
wxDATAVIEW_CELL_ACTIVATABLE,
wxDATAVIEW_CELL_EDITABLE
};

{
wxDATAVIEW_CELL_SELECTED = 1,
wxDATAVIEW_CELL_PRELIT = 2,
wxDATAVIEW_CELL_INSENSITIVE = 4,
wxDATAVIEW_CELL_FOCUSED = 8

\membersection{wxDataViewRenderer::wxDataViewRenderer}\label{wxdataviewrendererwxdataviewrenderer}
\func{}{wxDataViewRenderer}{\param{const wxString\& }{varianttype}, \param{wxDataViewCellMode }{mode = wxDATAVIEW\_CELL\_INERT}}
Constructor.
\membersection{wxDataViewRenderer::GetMode}\label{wxdataviewrenderergetmode}
\func{virtual wxDataViewCellMode}{GetMode}{\void}
Returns the cell mode.
\membersection{wxDataViewRenderer::GetOwner}\label{wxdataviewrenderergetowner}
\func{virtual wxDataViewColumn*}{GetOwner}{\void}
Returns pointer to the owning \helpref{wxDataViewColumn}{wxdataviewcolumn}.
\membersection{wxDataViewRenderer::GetValue}\label{wxdataviewrenderergetvalue}
\func{virtual bool}{GetValue}{\param{wxVariant\& }{value}}
This methods retrieves the value from the renderer in order to
transfer the value back to the data model. Returns {\it false}
on failure.
\membersection{wxDataViewRenderer::GetVariantType}\label{wxdataviewrenderergetvarianttype}
\func{virtual wxString}{GetVariantType}{\void}
Returns a string with the type of the \helpref{wxVariant}{wxvariant}
supported by this renderer.
\membersection{wxDataViewRenderer::SetOwner}\label{wxdataviewrenderersetowner}
\func{virtual void}{SetOwner}{\param{wxDataViewColumn* }{owner}}
Sets the owning \helpref{wxDataViewColumn}{wxdataviewcolumn}. This
is usually called from within wxDataViewColumn.
\membersection{wxDataViewRenderer::SetValue}\label{wxdataviewrenderersetvalue}
\func{virtual bool}{SetValue}{\param{const wxVariant\& }{value}}
Set the value of the renderer (and thus its cell) to {\it value}.
The internal code will then render this cell with this data.

\func{virtual bool}{Validate}{\param{wxVariant\& }{value}}
To be implemented.

\membersection{wxDataViewCustomRenderer::GetDC}\label{wxdataviewcustomrenderergetdc}
\func{virtual wxDC*}{GetDC}{\void}
Create DC on request. Internal.
\membersection{wxDataViewCustomRenderer::GetSize}\label{wxdataviewcustomrenderergetsize}

Override this to render the cell. Before this is called,
\helpref{SetValue}{wxdataviewrenderersetvalue} was called
so that this instance knows what to render.
