- status text is now restored after wxMenu help is shown in it
- bug in wxWindow::RemoveEventHandler() fixed (Yingjun Zhang)
- make it possible to use wxRTTI macros with namespaces (Benjamin I. Williams)
+- wxColourDatabase API now uses objects instead of pointers

\section{\class{wxColourDatabase}}\label{wxcolourdatabase}
wxWindows maintains a database of standard RGB colours for a predefined
set of named colours (such as ``BLACK'', ``LIGHT GREY''). The
-application may add to this set if desired by using {\it Append}. There
-is only one instance of this class: {\bf wxTheColourDatabase}.
+application may add to this set if desired by using
+\helpref{AddColour}{wxcolourdatabaseaddcolour} and may use it to look up
+colours by names using \helpref{Find}{wxcolourdatabasefind} or find the names
+for the standard colour suing \helpref{FindName}{wxcolourdatabasefindname}.
+
+There is one predefined instance of this class called
+{\bf wxTheColourDatabase}.
\wxheading{Derived from}
\wxheading{Remarks}
-The colours in the standard database are as follows:
+The standard database contains at least the following colours:
AQUAMARINE, BLACK, BLUE, BLUE VIOLET, BROWN, CADET BLUE, CORAL,
CORNFLOWER BLUE, CYAN, DARK GREY, DARK GREEN, DARK OLIVE GREEN, DARK

\membersection{wxColourDatabase::wxColourDatabase}\label{wxcolourdatabaseconstr}
\func{}{wxColourDatabase}{\void}

+\func{void}{AddColour}{\param{const wxString\& }{colourName}, \param{const wxColour\&}{colour}}
+
\func{void}{AddColour}{\param{const wxString\& }{colourName}, \param{wxColour* }{colour}}
Adds a colour to the database. If a colour with the same name already exists,
it is replaced.
+Please note that the overload taking a pointer is deprecated and will be

+
+
+\membersection{wxColourDatabase::Find}\label{wxcolourdatabasefind}
+
+\func{wxColour}{FindColour}{\param{const wxString\& }{colourName}}
+
+Finds a colour given the name. Returns an invalid colour object (that is, such
+that its \helpref{Ok()}{wxcolourok} method returns \false) if the colour wasn't
+found in the database.
+
+
\membersection{wxColourDatabase::FindColour}\label{wxcolourdatabasefindcolour}
\func{wxColour*}{FindColour}{\param{const wxString\& }{colourName}}
-Finds a colour given the name. Returns NULL if not found.
+Finds a colour given the name. Returns \NULL if not found or a pointer which
+must be deleted by the caller otherwise.
-\membersection{wxColourDatabase::FindName}\label{wxcolourdatabasefindname}

+wxWindows version, please use \helpref{Find}{wxcolourdatabasefind} instead of

-\func{void}{Initialize}{\void}
+\constfunc{wxString}{FindName}{\param{const wxColour\&}{ colour}}
-Initializes the database with a number of stock colours. Called by wxWindows
-on start-up.
+Finds a colour name given the colour. Returns an empty string if the colour is
+not found in the database.
