 109 "The wx.ArtProvider class is used to customize the look of wxWidgets
 110 application. When wxWidgets needs to display an icon or a bitmap (e.g.
 111 in the standard file dialog), it does not use hard-coded resource but
 112 asks wx.ArtProvider for it instead. This way the users can plug in
 113 their own wx.ArtProvider class and easily replace standard art with
 114 his/her own version. It is easy thing to do: all that is needed is
 115 to derive a class from wx.ArtProvider, override it's CreateBitmap
 116 method and register the provider with wx.ArtProvider.PushProvider::
 117
 118     class MyArtProvider(wx.ArtProvider):
 119         def __init__(self):
 120             wx.ArtProvider.__init__(self)
 121
 122         def CreateBitmap(self, artid, client, size):
 123             ...
 124             return bmp
 125
 126
 127 Identifying art resources
 128 -------------------------
 129
 130 Every bitmap is known to wx.ArtProvider under an unique ID that is
 131 used when requesting a resource from it. The IDs can have one of these
 132 predefined values:
 133
 134     * wx.ART_ADD_BOOKMARK
 135     * wx.ART_DEL_BOOKMARK
 136     * wx.ART_HELP_SIDE_PANEL
 137     * wx.ART_HELP_SETTINGS
 138     * wx.ART_HELP_BOOK
 139     * wx.ART_HELP_FOLDER
 140     * wx.ART_HELP_PAGE
 141     * wx.ART_GO_BACK
 142     * wx.ART_GO_FORWARD
 143     * wx.ART_GO_UP
 144     * wx.ART_GO_DOWN
 145     * wx.ART_GO_TO_PARENT
 146     * wx.ART_GO_HOME
 147     * wx.ART_FILE_OPEN
 148     * wx.ART_PRINT
 149     * wx.ART_HELP
 150     * wx.ART_TIP
 151     * wx.ART_REPORT_VIEW
 152     * wx.ART_LIST_VIEW
 153     * wx.ART_NEW_DIR
 154     * wx.ART_FOLDER
 155     * wx.ART_GO_DIR_UP
 156     * wx.ART_EXECUTABLE_FILE
 157     * wx.ART_NORMAL_FILE
 158     * wx.ART_TICK_MARK
 159     * wx.ART_CROSS_MARK
 160     * wx.ART_ERROR
 161     * wx.ART_QUESTION
 162     * wx.ART_WARNING
 163     * wx.ART_INFORMATION
 164     * wx.ART_MISSING_IMAGE

 167 Clients
 168 -------
 169
 170 The Client is the entity that calls wx.ArtProvider's `GetBitmap` or
 171 `GetIcon` function.  Client IDs server as a hint to wx.ArtProvider
 172 that is supposed to help it to choose the best looking bitmap. For
 173 example it is often desirable to use slightly different icons in menus
 174 and toolbars even though they represent the same action (e.g.
 175 wx.ART_FILE_OPEN). Remember that this is really only a hint for
 176 wx.ArtProvider -- it is common that `wx.ArtProvider.GetBitmap` returns
 177 identical bitmap for different client values!
 178
 179     * wx.ART_TOOLBAR
 180     * wx.ART_MENU
 181     * wx.ART_FRAME_ICON
 182     * wx.ART_CMN_DIALOG
 183     * wx.ART_HELP_BROWSER
 184     * wx.ART_MESSAGE_BOX
 185     * wx.ART_OTHER (used for all requests that don't fit into any
 186       of the categories above)
