+\section{\class{wxDelegateRendererNative}}\label{wxdelegaterenderernative}
+
+wxDelegateRendererNative allows reuse of renderers code by forwarding all the
+\helpref{wxRendererNative}{wxrenderernative} methods to the given object and
+thus allowing you to only modify some of its methods -- without having to
+reimplement all of them.
+
+Note that the ``normal'', inheritance-based approach, doesn't work with the
+renderers as it is impossible to derive from a class unknown at compile-time
+and the renderer is only chosen at run-time. So suppose that you want to only
+add something to the drawing of the tree control buttons but leave all the
+other methods unchanged -- the only way to do it, considering that the renderer
+class which you want to customize might not even be written yet when you write
+your code (it could be written later and loaded from a DLL during run-time), is
+by using this class.
+
+Except for the constructor, it has exactly the same methods as
+\helpref{wxRendererNative}{wxrenderernative} and their implementation is
+trivial: they are simply forwarded to the real renderer. Note that the ``real''
+renderer may, in turn, be a wxDelegateRendererNative as well and that there may
+be arbitrarily many levels like this -- but at the end of the chain there must
+be a real renderer which does the drawing.

+
+The default constructor does the same thing as the other one except that it
+uses the \helpref{generic renderer}{wxrenderernativegetgeneric} instead of the
+user-specified \arg{rendererNative}.
+
+In any case, this sets up the delegate renderer object to follow all calls to
+the specified real renderer.

First, a brief introduction into what is wxRenderer and why is it needed.
renderer but it may be changed or extended by the user, see
\helpref{Render sample}{samplerender}.
+All drawing functions take some standard parameters:
+\begin{itemize}
+ \item \arg{win} is the window being drawn. it is normally not used and when
+ it is it should only be used as a generic \helpref{wxWindow}{wxwindow}
+ (in order to get its low level handle, for example), but you should
+ \emph{not} assume that it is of some given type as the same renderer
+ function may be reused for drawing different kinds of control.
+ \item \arg{dc} is the \helpref{wxDC}{wxdc} to draw on, only this device
+ context should be used for drawing. It is not necessary to restore
+ pens and brushes for it on function exit but, on the other hand, you
+ shouldn't assume that it is in any specific state on function entry
+ neither: the rendering functions should always prepare it.
+ \item \arg{rect} the bounding rectangle for the element to be drawn
+ \item \arg{flags} the optional flags (none by default) which can be a
+ combination of the \texttt{wxCONTROL\_XXX} constants below
+\end{itemize}
+
+\wxheading{Constants}
+
+The following rendering flags are defined:
+\begin{verbatim}
+enum
+{
+ wxCONTROL_DISABLED = 0x00000001, // control is disabled
+ wxCONTROL_FOCUSED = 0x00000002, // currently has keyboard focus
+ wxCONTROL_PRESSED = 0x00000004, // (button) is pressed
+ wxCONTROL_ISDEFAULT = 0x00000008, // only applies to the buttons
+ wxCONTROL_ISSUBMENU = wxCONTROL_ISDEFAULT, // only for menu items
+ wxCONTROL_EXPANDED = wxCONTROL_ISDEFAULT, // only for the tree items
+ wxCONTROL_CURRENT = 0x00000010, // mouse is currently over the control
+ wxCONTROL_SELECTED = 0x00000020, // selected item in e.g. listbox
+ wxCONTROL_CHECKED = 0x00000040, // (check/radio button) is checked
+ wxCONTROL_CHECKABLE = 0x00000080 // (menu) item can be checked

+\membersection{wxRendererNative::\destruct{wxRendererNative}}\label{wxrenderernativedtor}
+
+\func{}{\destruct{wxRendererNative}}{\void}
+
+Virtual destructor as for any base class.
+
+
+\membersection{wxRendererNative::DrawHeaderButton}\label{wxrenderernativedrawheaderbutton}
+
+\func{void}{DrawHeaderButton}{\param{wxWindow* }{win}, \param{wxDC\& }{dc}, \param{const wxRect\& }{rect}, \param{int }{flags = 0}}
+
+Draw the header control button (used by \helpref{wxListCtrl}{wxlistctrl}).
+
+
+\membersection{wxRendererNative::DrawSplitterBorder}\label{wxrenderernativedrawsplitterborder}
+
+\func{void}{DrawSplitterBorder}{\param{wxWindow* }{win}, \param{wxDC\& }{dc}, \param{const wxRect\& }{rect}, \param{int }{flags = 0}}
+
+Draw the border for sash window: this border must be such that the sash
+drawn by \helpref{DrawSash}{wxrenderernativedrawsplittersash} blends into it
+well.
+
+
+\membersection{wxRendererNative::DrawSplitterSash}\label{wxrenderernativedrawsplittersash}
+
+\func{void}{DrawSplitterSash}{\param{wxWindow* }{win}, \param{wxDC\& }{dc}, \param{const wxSize\& }{size}, \param{wxCoord }{position}, \param{wxOrientation }{orient}, \param{int }{flags = 0}}
+
+Draw a sash. The \arg{orient} parameter defines whether the sash should be
+vertical or horizontal and how should the \arg{position} be interpreted.
+
+
+\membersection{wxRendererNative::DrawTreeItemButton}\label{wxrenderernativedrawtreeitembutton}
+
+\func{void}{DrawTreeItemButton}{\param{wxWindow* }{win}, \param{wxDC\& }{dc}, \param{const wxRect\& }{rect}, \param{int }{flags = 0}}
+
+Draw the expanded/collapsed icon for a tree control item. To draw an expanded
+button the \arg{flags} parameter must contain {\tt wxCONTROL\_EXPANDED} bit.
+
+
+\membersection{wxRendererNative::Get}\label{wxrenderernativeget}
+
+\func{wxRendererNative\&}{Get}{\void}
+
+Return the currently used renderer.
+
+
+\membersection{wxRendererNative::GetDefault}\label{wxrenderernativegetdefault}
+
+\func{wxRendererNative\&}{GetDefault}{\void}
+
+Return the default (native) implementation for this platform -- this is also
+the one used by default but this may be changed by calling
+\helpref{Set}{wxrenderernativeset} in which case the return value of this
+method may be different from the return value of \helpref{Get}{wxrenderernativeget}.
+
+
+\membersection{wxRendererNative::GetGeneric}\label{wxrenderernativegetgeneric}
+
+\func{wxRendererNative\&}{GetGeneric}{\void}
+
+Return the generic implementation of the renderer. Under some platforms, this
+is the default renderer implementation, others have platform-specific default
+renderer which can be retrieved by calling \helpref{GetDefault}{wxrenderernativegetdefault}.
+
+
+\membersection{wxRendererNative::GetSplitterParams}\label{wxrenderernativegetsplitterparams}
+
+\func{wxSplitterRenderParams}{GetSplitterParams}{\param{const wxWindow* }{win}}
+
+Get the splitter parameters, see
+\helpref{wxSplitterRenderParams}{wxsplitterrenderparams}.
+
+
+\membersection{wxRendererNative::GetVersion}\label{wxrenderernativegetversion}
+
+\constfunc{wxRendererVersion}{GetVersion}{\void}
+
+This function is used for version checking: \helpref{Load}{wxrenderernativeload}
+refuses to load any shared libraries implementing an older or incompatible
+version.
+
+The implementation of this method is always the same in all renderers (simply
+construct \helpref{wxRendererVersion}{wxrendererversion} using the
+{\tt wxRendererVersion::Current\_XXX} values), but it has to be in the derived,
+not base, class, to detect mismatches between the renderers versions and so you
+have to implement it anew in all renderers.
+
+
+\membersection{wxRendererNative::Load}\label{wxrenderernativeload}
+
+\func{wxRendererNative*}{Load}{\param{const wxString\& }{name}}
+
+Load the renderer from the specified DLL, the returned pointer must be
+deleted by caller if not {\tt NULL} when it is not used any more.
+
+The \arg{name} should be just the base name of the renderer and not the full
+name of the DLL file which is constructed differently (using
+\helpref{wxDynamicLibrary::CanonicalizePluginName}{wxdynamiclibrarycanonicalizepluginname})
+on different systems.
+
+
+\membersection{wxRendererNative::Set}\label{wxrenderernativeset}
+
+\func{wxRendererNative*}{Set}{\param{wxRendererNative* }{renderer}}
+
+Set the renderer to use, passing {\tt NULL} reverts to using the default
+renderer (the global renderer must always exist).
+
+Return the previous renderer used with Set() or {\tt NULL} if none.

+\section{\class{wxRendererVersion}}\label{wxrendererversion}
+
+This simple struct represents the \helpref{wxRendererNative}{wxrenderernative}
+interface version and is only used as the return value of
+\helpref{wxRendererNative::GetVersion}{wxrenderernativegetversion}.
+
+The version has two components: the version itself and the age. If the main
+program and the renderer have different versions they are never compatible with
+each other because the version is only changed when an existing virtual
+function is modified or removed. The age, on the other hand, is incremented
+each time a new virtual method is added and so, at least for the compilers
+using a common C++ object model, the calling program is compatible with any
+renderer which has the age greater or equal to its age. This verification is
+done by \helpref{IsCompatible}{wxrenderernativeiscompatible} method.
