  # 
  # An FXFoldingList widget resembles an FXTreeList, but it supports a
  # header control to provide each item with multiple columns of text.
  # Subtrees can be collapsed or expanded by double-clicking on an item
  # or by clicking on the optional plus button in front of the item.
  # Each item may have a text and optional open-icon as well as a closed-icon.
  # The items may be connected by optional lines to show the hierarchical
  # relationship.
  # When an item's selected state changes, the folding list emits a +SEL_SELECTED+
  # or +SEL_DESELECTED+ message. If an item is opened or closed, a message
  # of type +SEL_OPENED+ or +SEL_CLOSED+ is sent. When the subtree under an
  # item is expanded, a +SEL_EXPANDED+ or +SEL_COLLAPSED+ message is issued.
  # A change of the current item is signified by the +SEL_CHANGED+ message.
  # In addition, the folding 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 or removed, the folding list sends messages of the
  # type +SEL_INSERTED+ or +SEL_DELETED+.
  # In each of these cases, a pointer to the item, if any, is passed in the
  # 3rd argument of the message.
  #
  # === Events
  #
  # The following messages are sent by FXFoldingList to its target:
  #
  # +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_COMMAND+::		sent when a list item is clicked on; the message data is a reference to the item (an FXFoldingItem instance).
  # +SEL_CLICKED+::		sent when the left mouse button is single-clicked in the list; the message data is a reference to the item clicked (an FXFoldingItem instance) or +nil+ if no item was clicked.
  # +SEL_DOUBLECLICKED+::	sent when the left mouse button is double-clicked in the list; the message data is a reference to the item clicked (an FXFoldingItem instance) or +nil+ if no item was clicked.
  # +SEL_TRIPLECLICKED+::	sent when the left mouse button is triple-clicked in the list; the message data is a reference to the item clicked (an FXFoldingItem instance) or +nil+ if no item was clicked.
  # +SEL_OPENED+::		sent when an item is opened; the message data is a reference to the item (an FXFoldingItem instance).
  # +SEL_CLOSED+::		sent when an item is closed; the message data is a reference to the item (an FXFoldingItem instance).
  # +SEL_EXPANDED+::		sent when a sub-tree is expanded; the message data is a reference to the root item for the sub-tree (an FXFoldingItem instance).
  # +SEL_COLLAPSED+::		sent when a sub-tree is collapsed; the message data is a reference to the root item for the sub-tree (an FXFoldingItem instance).
  # +SEL_SELECTED+::		sent when an item is selected; the message data is a reference to the item (an FXFoldingItem instance).
  # +SEL_DESELECTED+::		sent when an item is deselected; the message data is a reference to the item (an FXFoldingItem instance).
  # +SEL_CHANGED+::		sent when the current item changes; the message data is a reference to the current item (an FXFoldingItem instance).
  # +SEL_INSERTED+::		sent after an item is added to the list; the message data is a reference to the item (an FXFoldingItem instance).
  # +SEL_DELETED+::		sent before an item is removed from the list; the message data is a reference to the item (an FXFoldingItem instance).
  #
  # === Folding list styles
  #
  # +FOLDINGLIST_EXTENDEDSELECT+::		Extended selection mode allows for drag-selection of ranges of items
  # +FOLDINGLIST_SINGLESELECT+::		Single selection mode allows up to one item to be selected
  # +FOLDINGLIST_BROWSESELECT+::		Browse selection mode enforces one single item to be selected at all times
  # +FOLDINGLIST_MULTIPLESELECT+::		Multiple selection mode is used for selection of individual items
  # +FOLDINGLIST_AUTOSELECT+::			Automatically select under cursor
  # +FOLDINGLIST_SHOWS_LINES+::			Lines shown
  # +FOLDINGLIST_SHOWS_BOXES+::			Boxes to expand shown
  # +FOLDINGLIST_ROOT_BOXES+::			Display root boxes also
  # +FOLDINGLIST_NORMAL+::			same as +FOLDINGLIST_EXTENDEDSELECT+
