# Example plugin for EditorFunctions type plugins
#
# The plugin allows to install new menu items and toolbar items and register a
# a function with each that is called. The function must accept one argument which
# is the instance of PersonalWikiFrame providing access to the editor and the data store.
#
# To register a menu item implement the function describeMenuItem to return a
# sequence of tuples at least containing the callback function, the item string
# and an item tooltip (see below for details).
#
# To register a toolbar item implement the function describeToolbarItem to return
# a tuple at least containing the callback function, item label, tooltip and icon.
#
# both register functions must accept one argument which is again the
# PersonalWikiFrame instance

# descriptor for EditorFunctions plugin type

        - callback function
        - menu item string
        - menu item description (string to show in status bar)
    It can contain the following additional items (in this order), each of
    them can be replaced by None:
        - icon descriptor (see below, if no icon found, it won't show one)
        - menu item id.

    The  callback function  must take 2 parameters:
        wiki - Calling PersonalWikiFrame
        evt - wx.CommandEvent

    An  icon descriptor  can be one of the following:
        - a wx.Bitmap object
        - the filename of a bitmap (if file not found, no icon is used)
        - a tuple of filenames, first existing file is used
