 127 "The wx.ArtProvider class is used to customize the look of wxWidgets
 128 application. When wxWidgets needs to display an icon or a bitmap (e.g.
 129 in the standard file dialog), it does not use hard-coded resource but
 130 asks wx.ArtProvider for it instead. This way the users can plug in
 131 their own wx.ArtProvider class and easily replace standard art with
 132 his/her own version. It is easy thing to do: all that is needed is
 133 to derive a class from wx.ArtProvider, override it's CreateBitmap
 134 method and register the provider with wx.ArtProvider.PushProvider::
 135
 136     class MyArtProvider(wx.ArtProvider):
 137         def __init__(self):
 138             wx.ArtProvider.__init__(self)
 139
 140         def CreateBitmap(self, artid, client, size):
 141             ...
 142             return bmp
 143 ", "
 144
 145 Identifying art resources
 146 -------------------------
 147
 148 Every bitmap is known to wx.ArtProvider under an unique ID that is
 149 used when requesting a resource from it. The IDs can have one of the
 150 following predefined values.  Additionally, any string recognized by
 151 custom art providers registered using `PushProvider` may be used.
 152
 153 GTK+ Note
 154 ---------
 155
 156 When running under GTK+ 2, GTK+ stock item IDs (e.g. 'gtk-cdrom') may be used
 157 as well.  Additionally, if wxGTK was compiled against GTK+ >= 2.4, then it is
 158 also possible to load icons from current icon theme by specifying their name
 159 without the extension and directory components. Icon themes recognized by GTK+
 160 follow the freedesktop.org Icon Themes specification.  Note that themes are
 161 not guaranteed to contain all icons, so wx.ArtProvider may return wx.NullBitmap
 162 or wx.NullIcon.  The default theme is typically installed in /usr/share/icons/hicolor.

 214 Clients
 215 -------
 216
 217 The Client is the entity that calls wx.ArtProvider's `GetBitmap` or
 218 `GetIcon` function.  Client IDs serve as a hint to wx.ArtProvider
 219 that is supposed to help it to choose the best looking bitmap. For
 220 example it is often desirable to use slightly different icons in menus
 221 and toolbars even though they represent the same action (e.g.
 222 wx.ART_FILE_OPEN). Remember that this is really only a hint for
 223 wx.ArtProvider -- it is common that `wx.ArtProvider.GetBitmap` returns
 224 identical bitmap for different client values!
