DocStr(wxPyArtProvider,
"The wx.ArtProvider 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 dialog), it does not use hard-coded resource but
asks wx.ArtProvider for it instead. This way the users can plug in
their own wx.ArtProvider 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 wx.ArtProvider, override it's CreateBitmap
method and register the provider with wx.ArtProvider.PushProvider::

    class MyArtProvider(wx.ArtProvider):
        def __init__(self):
            wx.ArtProvider.__init__(self)

        def CreateBitmap(self, artid, client, size):
            ...
            return bmp
", "

Identifying art resources
-------------------------

Every bitmap is known to wx.ArtProvider under an unique ID that is
used when requesting a resource from it. The IDs can have one of the
following predefined values.  Additionally, any string recognized by
custom art providers registered using `PushProvider` may be used.

GTK+ Note
---------

When running under GTK+ 2, GTK+ stock item IDs (e.g. '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 the extension and directory components. Icon themes recognized by GTK+
follow the freedesktop.org Icon Themes specification.  Note that themes are
not guaranteed to contain all icons, so wx.ArtProvider may return wx.NullBitmap
or wx.NullIcon.  The default theme is typically installed in /usr/share/icons/hicolor.

Clients
-------

The Client is the entity that calls wx.ArtProvider's `GetBitmap` or
`GetIcon` function.  Client IDs serve as a hint to wx.ArtProvider
that is supposed to help it to choose the best looking bitmap. For
example it is often desirable to use slightly different icons in menus
and toolbars even though they represent the same action (e.g.
wx.ART_FILE_OPEN). Remember that this is really only a hint for
wx.ArtProvider -- it is common that `wx.ArtProvider.GetBitmap` returns
identical bitmap for different client values!
