  # A List Widget displays a list of items, each with a text and
  # optional icon.  When an item's selected state changes, the list sends
  # a +SEL_SELECTED+ or +SEL_DESELECTED+ message.  A change of the current
  # item is signified by the +SEL_CHANGED+ message.
  # The list sends +SEL_COMMAND+ messages when the user clicks on an item,
  # and +SEL_CLICKED+, +SEL_DOUBLECLICKED+, and +SEL_TRIPLECLICKED+ when the user
  # clicks once, twice, or thrice, respectively.
  # When items are added, replaced, or removed, the list sends messages of
  # the type +SEL_INSERTED+, +SEL_REPLACED+, or +SEL_DELETED+.
  # In each of these cases, the index to the item, if any, is passed in the
  # 3rd argument of the message.
  #
  # === Events
  #
  # The following messages are sent by FXList to its target:
  #
  # +SEL_CHANGED+::		sent when the current list item changes; the message data is an Integer indicating the index of the current item.
  # +SEL_COMMAND+::		sent when the current list item changes; the message data is an Integer indicating the index of the current item.
  # +SEL_KEYPRESS+::		sent when a key goes down; the message data is an FXEvent instance.
  # +SEL_KEYRELEASE+::		sent when a key goes up; the message data is an FXEvent instance.
  # +SEL_LEFTBUTTONPRESS+::	sent when the left mouse button goes down; the message data is an FXEvent instance.
  # +SEL_LEFTBUTTONRELEASE+::	sent when the left mouse button goes up; the message data is an FXEvent instance.
  # +SEL_RIGHTBUTTONPRESS+::	sent when the right mouse button goes down; the message data is an FXEvent instance.
  # +SEL_RIGHTBUTTONRELEASE+::	sent when the right mouse button goes up; the message data is an FXEvent instance.
  # +SEL_CLICKED+::		sent when a list item is single-clicked; the message data is an Integer indicating the index of the current item.
  # +SEL_DOUBLECLICKED+::	sent when a list item is double-clicked; the message data is an Integer indicating the index of the current item.
  # +SEL_TRIPLECLICKED+::	sent when a list item is triple-clicked; the message data is an Integer indicating the index of the current item.
  # +SEL_SELECTED+::		sent when a list item is selected; the message data is an Integer indicating the index of the selected item.
  # +SEL_DESELECTED+::		sent when a list item is deselected; the message data is an Integer indicating the index of the deselected item.
  # +SEL_REPLACED+::		sent when a list item is about to be replaced; the message data is an Integer indicating the index of the item to be replaced.
  # +SEL_INSERTED+::		sent after a list item is inserted; the message data is an Integer indicating the index of the item that was inserted.
  # +SEL_DELETED+::		sent when a list item is about to be removed; the message data is an Integer indicating the index of the item to be removed.
  #
  # === List styles
  #
  # +LIST_EXTENDEDSELECT+::	Extended selection mode allows for drag-selection of ranges of items
  # +LIST_SINGLESELECT+::	Single selection mode allows up to one item to be selected
  # +LIST_BROWSESELECT+::	Browse selection mode enforces one single item to be selected at all times
  # +LIST_MULTIPLESELECT+::	Multiple selection mode is used for selection of individual items
  # +LIST_AUTOSELECT+::		Automatically select under cursor
  # +LIST_NORMAL+::		same as +LIST_EXTENDEDSELECT+
  #
  # === Message identifiers
  #
  # +ID_TIPTIMER+::
  # +ID_LOOKUPTIMER+::
