\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
-that is needed is to derive a class from wxArtProvider, override it's
-\helpref{CreateBitmap}{wxartprovidercreatebitmap} method and register the
-provider with

+wxArtProvider class is used to customize the look of wxWidgets application.
+When wxWidgets needs to display an icon or a bitmap (e.g. in the standard file

+\helpref{CreateBitmap}{wxartprovidercreatebitmap} and/or its
+\helpref{CreateIconBundle}{wxartprovidercreateiconbundle} methods
+and register the provider with
+\helpref{wxArtProvider::Push}{wxartproviderpush}:
\begin{verbatim}
class MyProvider : public wxArtProvider
wxBitmap CreateBitmap(const wxArtID& id,
const wxArtClient& client,
const wxSize size)
+
+ // optionally override this one as well
+ wxIconBundle CreateIconBundle(const wxArtID& id,
+ const wxArtClient& client)
{ ... }
};
...
- wxArtProvider::PushProvider(new MyProvider);
+ wxArtProvider::Push(new MyProvider);
\end{verbatim}
+If you need bitmap images (of the same artwork) that should be displayed at different sizes
+you should probably consider overriding \helpref{CreateIconBundle()}{wxartprovidercreateiconbundle}
+and supplying icon bundles that contain different bitmap sizes.
+
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
-possible as of wxWindows 2.3.3, the set of wxArtProvider bitmaps is too
+possible as of wxWidgets 2.3.3, the set of wxArtProvider bitmaps is too
small).

+\membersection{Identifying art resources}\label{artprovideridentifying}
+
+Every bitmap and icon bundle are known to wxArtProvider under an unique ID that is used when
requesting a resource from it. The ID is represented by wxArtID type and can
have one of these predefined values (you can see bitmaps represented by these
constants in the \helpref{artprov}{sampleartprovider} sample):

-\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

-Derived art provider classes must override this method to create requested

-not neccessary to optimize CreateBitmap for speed (e.g. you may create wxBitmap objects
-from XPMs here).

This only servers as a hint.}
