 115 "The wx.ArtProvider class is used to customize the look of wxWidgets
 116 application. When wxWidgets needs to display an icon or a bitmap (e.g.
 117 in the standard file dialog), it does not use hard-coded resource but
 118 asks wx.ArtProvider for it instead. This way the users can plug in
 119 their own wx.ArtProvider class and easily replace standard art with
 120 his/her own version. It is easy thing to do: all that is needed is
 121 to derive a class from wx.ArtProvider, override it's CreateBitmap
 122 method and register the provider with wx.ArtProvider.PushProvider::
 123
 124     class MyArtProvider(wx.ArtProvider):
 125         def __init__(self):
 126             wx.ArtProvider.__init__(self)
 127
 128         def CreateBitmap(self, artid, client, size):
 129             ...
 130             return bmp
 131 ", "
 132
 133 Identifying art resources
 134 -------------------------
 135
 136 Every bitmap is known to wx.ArtProvider under an unique ID that is
 137 used when requesting a resource from it. The IDs can have one of the
 138 following predefined values.  Additionally, any string recognized by
 139 custom art providers registered using `PushProvider` may be used.
 140
 141 GTK+ Note
 142 ---------
 143
 144 When running under GTK+ 2, GTK+ stock item IDs (e.g. 'gtk-cdrom') may be used
 145 as well.  Additionally, if wxGTK was compiled against GTK+ >= 2.4, then it is
 146 also possible to load icons from current icon theme by specifying their name
 147 without the extension and directory components. Icon themes recognized by GTK+
 148 follow the freedesktop.org Icon Themes specification.  Note that themes are
 149 not guaranteed to contain all icons, so wx.ArtProvider may return wx.NullBitmap
 150 or wx.NullIcon.  The default theme is typically installed in /usr/share/icons/hicolor.

 186 Clients
 187 -------
 188
 189 The Client is the entity that calls wx.ArtProvider's `GetBitmap` or
 190 `GetIcon` function.  Client IDs serve as a hint to wx.ArtProvider
 191 that is supposed to help it to choose the best looking bitmap. For
 192 example it is often desirable to use slightly different icons in menus
 193 and toolbars even though they represent the same action (e.g.
 194 wx.ART_FILE_OPEN). Remember that this is really only a hint for
 195 wx.ArtProvider -- it is common that `wx.ArtProvider.GetBitmap` returns
 196 identical bitmap for different client values!
