First, a brief introduction to wxRenderer and why it is needed.
-Usually wxWindows uses the underlying low level GUI system to draw all the
-controls -- this is what we mean when we say that it is a ``native'' framework.
+Usually wxWidgets uses the underlying low level GUI system to draw all the
+controls - this is what we mean when we say that it is a ``native'' framework.
However not all controls exist under all (or even any) platforms and in this
-case wxWindows provides a default, generic, implementation of them written in
-wxWindows itself.

These controls don't have the native appearance if only the standard
line drawing and other graphics primitives are used, because the native
combination of the \texttt{wxCONTROL\_XXX} constants below.

+Note that each drawing function restores the \helpref{wxDC}{wxdc} attributes if
+it changes them, so it is safe to assume that the same pen, brush and colours
+that were active before the call to this function are still in effect after it.

\wxheading{Constants}
The following rendering flags are defined:
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_SPECIAL = 0x00000008, // control-specific bit:
+ wxCONTROL_ISDEFAULT = wxCONTROL_SPECIAL, // only for the buttons
+ wxCONTROL_ISSUBMENU = wxCONTROL_SPECIAL, // only for the menu items
+ wxCONTROL_EXPANDED = wxCONTROL_SPECIAL, // only for the tree items
+ wxCONTROL_SIZEGRIP = wxCONTROL_SPECIAL, // only for the status bar panes
+ wxCONTROL_FLAT = wxCONTROL_SPECIAL, // checkboxes only: flat border
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
+ wxCONTROL_CHECKABLE = 0x00000080, // (menu) item can be checked

Virtual destructor as for any base class.
+\membersection{wxRendererNative::DrawCheckBox}\label{wxrenderernativedrawcheckbox}
+
+\func{void}{DrawCheckBox}{\param{wxWindow *}{win}, \param{wxDC\& }{dc}, \param{const wxRect\& }{rect}, \param{int }{flags}}
+
+Draw a check box (used by wxDataViewCtrl).
+
+\arg{flags} may have the \texttt{wxCONTROL\_CHECKED}, \texttt{wxCONTROL\_CURRENT} or
+\texttt{wxCONTROL\_UNDETERMINED} bit set.
+
+
+\membersection{wxRendererNative::DrawComboBoxDropButton}\label{wxrenderernativedrawcomboboxdropbutton}
+
+\func{void}{DrawComboBoxDropButton}{\param{wxWindow *}{win}, \param{wxDC\& }{dc}, \param{const wxRect\& }{rect}, \param{int }{flags}}
+
+Draw a button like the one used by \helpref{wxComboBox}{wxcombobox} to show a
+drop down window. The usual appearance is a downwards pointing arrow.
+
+\arg{flags} may have the \texttt{wxCONTROL\_PRESSED} or \texttt{wxCONTROL\_CURRENT} bit set.
+
+
+\membersection{wxRendererNative::DrawDropArrow}\label{wxrenderernativedrawdroparrow}
+
+\func{void}{DrawDropArrow}{\param{wxWindow *}{win}, \param{wxDC\& }{dc}, \param{const wxRect\& }{rect}, \param{int }{flags}}
+
+Draw a drop down arrow that is suitable for use outside a combo box. Arrow will have
+transparent background.
+
+\arg{rect} is not entirely filled by the arrow. Instead, you should use bounding
+rectangle of a drop down button which arrow matches the size you need.
+\arg{flags} may have the \texttt{wxCONTROL\_PRESSED} or \texttt{wxCONTROL\_CURRENT} bit set.
+
+
+\membersection{wxRendererNative::DrawFocusRect}\label{wxrenderernativedrawfocusrect}
+
+\func{void}{DrawFocusRect}{\param{wxWindow* }{win}, \param{wxDC\& }{dc}, \param{const wxRect\& }{rect}, \param{int }{flags = 0}}
+
+Draw a focus rectangle using the specified rectangle.

+\texttt{wxCONTROL\_SELECTED} for items which are selected.

-\func{void}{DrawHeaderButton}{\param{wxWindow* }{win}, \param{wxDC\& }{dc}, \param{const wxRect\& }{rect}, \param{int }{flags = 0}}
+\func{int}{DrawHeaderButton}{\param{wxWindow* }{win}, \param{wxDC\& }{dc}, \param{const wxRect\& }{rect}, \param{int }{flags = 0}, \param{wxHeaderSortIconType }{sortArrow = wxHDR\_SORT\_ICON\_NONE}, \param{wxHeaderButtonParams* }{params = NULL}}
+
+Draw the header control button (used, for example, by
+\helpref{wxListCtrl}{wxlistctrl}). Depending on platforms the
+\arg{flags} parameter may support the \texttt{wxCONTROL\_SELECTED}
+\texttt{wxCONTROL\_DISABLED} and \texttt{wxCONTROL\_CURRENT} bits.
+The \arg{sortArrow} parameter can be one of
+\texttt{wxHDR\_SORT\_ICON\_NONE}, \texttt{wxHDR\_SORT\_ICON\_UP}, or
+\texttt{wxHDR\_SORT\_ICON\_DOWN}. Additional values controlling the
+drawing of a text or bitmap label can be passed in \arg{params}. The
+value returned is the optimal width to contain the the unabreviated
+label text or bitmap, the sort arrow if present, and internal margins.

+\membersection{wxRendererNative::DrawItemSelectionRect}\label{wxrenderernativedrawitemselectionrect}
+
+\func{void}{DrawItemSelectionRect}{\param{wxWindow* }{win}, \param{wxDC\& }{dc}, \param{const wxRect\& }{rect}, \param{int }{flags = 0}}
-Draw the header control button (used by \helpref{wxListCtrl}{wxlistctrl}).
+Draw a selection rectangle underneath the text as used e.g. in a
+\helpref{wxListCtrl}{wxlistctrl}. The supported \arg{flags} are
+\texttt{wxCONTROL\_SELECTED} for items which are selected (e.g. often a blue
+rectangle) and \texttt{wxCONTROL\_CURRENT} for the item that has the focus
+(often a dotted line around the item's text). \texttt{wxCONTROL\_FOCUSED} may
+be used to indicate if the control has the focus (othewise the the selection
+rectangle is e.g. often grey and not blue). This may be ignored by the renderer
+or deduced by the code directly from the \arg{win}.

+\arg{flags} may have the \texttt{wxCONTROL\_PRESSED}, \texttt{wxCONTROL\_CURRENT} or
+\texttt{wxCONTROL\_ISDEFAULT} bit set.
\membersection{wxRendererNative::DrawSplitterBorder}\label{wxrenderernativedrawsplitterborder}
\func{void}{DrawSplitterSash}{\param{wxWindow* }{win}, \param{wxDC\& }{dc}, \param{const wxSize\& }{size}, \param{wxCoord }{position}, \param{wxOrientation }{orient}, \param{int }{flags = 0}}
