\section{\class{wxArtProvider}}\label{wxartprovider}
-wxArtProvider class is used to customize the look of wxWindows application.
-When wxWindows need to display an icon or a bitmap (e.g. in the standard file
-dialog), it does not use hard-coded resource but asks wxArtProvider for it
-instead. This way the users can plug in own wxArtProvider class and easily
-replace standard art with his/her own version. It is easy thing to do: all

+replace standard art with their own version. All

\helpref{CreateBitmap}{wxartprovidercreatebitmap} method and register the
provider with
-\helpref{wxArtProvider::PushProvider}{wxartproviderpushprovider}:

\begin{verbatim}
class MyProvider : public wxArtProvider
{ ... }
};
...
- wxArtProvider::PushProvider(new MyProvider);
+ wxArtProvider::Push(new MyProvider);
\end{verbatim}
There's another way of taking advantage of this class: you can use it in your code and use
-platform native icons as provided by
-\helpref{wxArtProvider::GetBitmap}{wxartprovidergetbitmap} or
+platform native icons as provided by \helpref{wxArtProvider::GetBitmap}{wxartprovidergetbitmap} or
\helpref{wxArtProvider::GetIcon}{wxartprovidergeticon} (NB: this is not yet really

+\membersection{Identifying art resources}\label{artprovideridentifying}
Every bitmap is known to wxArtProvider under an unique ID that is used by when
requesting a resource from it. The ID is represented by wxArtID type and can
\item wxART\_MISSING\_IMAGE
\end{itemize}
-\membersection{Clients}
+Additionally, any string recognized by custom art providers registered using
+\helpref{Push}{wxartproviderpush} may be used.
+
+\wxheading{GTK+ Note}
+
+When running under GTK+ 2, GTK+ stock item IDs (e.g. {\tt "gtk-cdrom"}) may
+be used as well. Additionally, if wxGTK was compiled against GTK+ >= 2.4, then
+it is also possible to load icons from current icon theme by specifying their
+name (without extension and directory components). Icon themes recognized
+by GTK+ follow the
+\urlref{freedesktop.org Icon Themes specification}{http://freedesktop.org/Standards/icon-theme-spec}. Note that themes are not guaranteed to contain all
+icons, so wxArtProvider may return {\tt wxNullBitmap} or {\tt wxNullIcon}.
+Default theme is typically installed in {\tt /usr/share/icons/hicolor}.
+
+
+\membersection{Clients}\label{artproviderclients}
Client is the entity that calls wxArtProvider's GetBitmap or GetIcon
function. It is represented by wxClientID type and can have one of these
\begin{itemize}\itemsep=0pt
\item wxART\_TOOLBAR
\item wxART\_MENU
+\item wxART\_BUTTON
\item wxART\_FRAME\_ICON
\item wxART\_CMN\_DIALOG
\item wxART\_HELP\_BROWSER

+\membersection{wxArtProvider::\destruct{wxArtProvider}}\label{wxartproviderdtor}
+
+\func{}{\destruct{wxArtProvider}}{\void}
+
+The destructor automatically removes the provider from the provider stack used
+by \helpref{GetBitmap}{wxartprovidergetbitmap}.
+
+
\membersection{wxArtProvider::CreateBitmap}\label{wxartprovidercreatebitmap}
\func{wxBitmap}{CreateBitmap}{\param{const wxArtID\& }{id}, \param{const wxArtClient\& }{client}, \param{const wxSize\& }{size}}
Derived art provider classes must override this method to create requested
art resource. Note that returned bitmaps are cached by wxArtProvider and it is therefore
-not neccessary to optimize CreateBitmap for speed (e.g. you may create wxBitmap objects
+not necessary to optimize CreateBitmap for speed (e.g. you may create wxBitmap objects
from XPMs here).
\wxheading{Parameters}
\docparam{client}{wxArtClient identifier of the client (i.e. who is asking for the bitmap).
This only servers as a hint.}
-\docparam{size}{Prefered size of the bitmap. The function may return a bitmap of different
+\docparam{size}{Preferred size of the bitmap. The function may return a bitmap of different
dimensions, it will be automatically rescaled to meet client's request.}
\wxheading{Note}
\helpref{wxArtProvider::GetIcon}{wxartprovidergeticon}
to query wxArtProvider for a resource.
+
+\membersection{wxArtProvider::Delete}\label{wxartproviderdelete}
+
+\func{static bool}{Delete}{\param{wxArtProvider* }{provider}}
+
+Delete the given \arg{provider}.
+
+
\membersection{wxArtProvider::GetBitmap}\label{wxartprovidergetbitmap}
\func{static wxBitmap}{GetBitmap}{\param{const wxArtID\& }{id}, \param{const wxArtClient\& }{client = wxART\_OTHER}, \param{const wxSize\& }{size = wxDefaultSize}}
The bitmap if one of registered providers recognizes the ID or wxNullBitmap otherwise.
+
\membersection{wxArtProvider::GetIcon}\label{wxartprovidergeticon}
\func{static wxIcon}{GetIcon}{\param{const wxArtID\& }{id}, \param{const wxArtClient\& }{client = wxART\_OTHER}, \param{const wxSize\& }{size = wxDefaultSize}}
Same as \helpref{wxArtProvider::GetBitmap}{wxartprovidergetbitmap}, but
return a wxIcon object (or wxNullIcon on failure).
-\membersection{wxArtProvider::PopProvider}\label{wxartproviderpopprovider}
+\func{static wxSize}{GetSizeHint}{\param{const wxArtClient\& }{client}, \param{bool }{platform\_default = false}}
+
+Returns a suitable size hint for the given {\it wxArtClient}. If
+{\it platform\_default} is \true, return a size based on the current platform,
+otherwise return the size from the topmost wxArtProvider. {\it wxDefaultSize} may be
+returned if the client doesn't have a specified size, like wxART\_OTHER for example.
+
+
+\membersection{wxArtProvider::Insert}\label{wxartproviderinsert}
+
+\func{static void}{Insert}{\param{wxArtProvider* }{provider}}
+
+Register new art provider and add it to the bottom of providers stack (i.e.
+it will be queried as the last one).

+\membersection{wxArtProvider::Push}\label{wxartproviderpush}
+
+\func{static void}{Push}{\param{wxArtProvider* }{provider}}
+
+Register new art provider and add it to the top of providers stack (i.e. it
+will be queried as the first provider).
+
+\wxheading{See also}
+
+\helpref{Insert}{wxartproviderinsert}
-Register new art provider (add it to the top of providers stack).

-\func{static bool}{RemoveProvider}{\param{wxArtProvider* }{provider}}
+\func{static bool}{Remove}{\param{wxArtProvider* }{provider}}
-Remove a provider from the stack. The provider must have been added previously
-and is {\it not} deleted.
+Remove a provider from the stack if it is on it. The provider is {\emph not}
