  # The List Box is a control to select one of a list of options.  It looks
  # similar to a Combo Box except that List Box yields integer numbers only.
  # When an option is selected, List Box will send an SEL_COMMAND with the
  # index of the opton.  While manipulating the list, it may send SEL_CHANGED
  # messages to indicate which option the cursor is hovering over.
  # The List Box is able to receive ID_GETINTVALUE and ID_SETINTVALUE which
  # will retrieve the current option or change the selected option.
  #
  # === Events
  #
  # The following messages are sent by FXListBox to its target:
  #
  # +SEL_COMMAND+::
  #   sent when a new list item is clicked; the message data is the index of the selected item.
  # +SEL_CHANGED+::
  #   sent when a new list item is clicked.
  #
  # === List Box styles
  #
  # +LISTBOX_NORMAL+::  Normal style
  #
  # === Message identifiers
  #
  # +ID_LIST+
  # +ID_FIELD+
