  # Header control may be placed over a table or list to provide a resizable
  # captions above a number of columns.
  # Each caption comprises a label and an optional icon; in addition, an arrow
  # may be shown to indicate whether the items in that column are sorted, and
  # if so, whether they are sorted in increasing or decreasing order.
  # Each caption can be interactively resized.  During the resizing, if the
  # HEADER_TRACKING was specified, the header control sends a SEL_CHANGED message
  # to its target, with the message data set to the caption number being resized,
  # of the type FXint.
  # If the HEADER_TRACKING was not specified the SEL_CHANGED message is sent at
  # the end of the resizing operation.
  # Clicking on a caption causes a message of type SEL_COMMAND to be sent to the
  # target, with the message data set to the caption number being clicked.
  # A single click on a split causes a message of type SEL_CLICKED to be sent to the
  # target; a typical response to this message would be to adjust the size of
  # the split to fit the contents displayed underneath it.
  # The contents may be scrolled by calling setPosition().
  #
  # === Events
  #
  # The following messages are sent by FXHeader to its target:
  #
  # +SEL_CHANGED+::
  #   sent continuously while a header item is being resized, if the
  #   +HEADER_TRACKING+ option was specified, or at the end of the resize
  #   if +HEADER_TRACKING+ was not specfied. The message data is an integer
  #   indicating the index of the item being resized.
  # +SEL_COMMAND+::
  #   sent when a header item is clicked; the message data is an integer
  #   indicating the index of the current item.
  # +SEL_CLICKED+::
  #   sent when a header item is clicked; the message data is an integer
  #   indicating the index of the current item.
  # +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_REPLACED+::		sent when a header 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 header item is inserted; the message data is an Integer indicating the index of the item that was inserted.
  # +SEL_DELETED+::		sent when a header item is about to be removed; the message data is an Integer indicating the index of the item to be removed.
  #
  # === Header style options
  #
  # +HEADER_BUTTON+::		Button style can be clicked
  # +HEADER_HORIZONTAL+::	Horizontal header control (default)
  # +HEADER_VERTICAL+::		Vertical header control
  # +HEADER_TRACKING+::		Tracks continuously while moving
  # +HEADER_RESIZE+::		Allow resizing sections
  # +HEADER_NORMAL+::		Normal options, same as <tt>HEADER_HORIZONTAL|FRAME_NORMAL</tt>
  #
  # === Message identifiers
  #
  # +ID_TIPTIMER+::		x
