  # A dock bar widget can be docked inside a dock site widget, or floated
  # around freely.  Users can move, undock, and dock the dock bar widget
  # by means of a handle such as a tool bar grip.  When docking, the dock
  # bar sends a +SEL_DOCKED+ message to its target; when undocking, it sends
  # a +SEL_FLOATED+ message. In either case the dock site involved is passed
  # as the message data.
  #
  # === Events
  #
  # The following messages are sent by FXDockBar to its target:
  #
  # +SEL_DOCKED+::  sent when the dock bar is docked; the message data is a reference to the new dock site (an FXDockSite instance).
  # +SEL_FLOATED+::  sent when the dock bar is undocked; the message data is a reference to the previous dock site.
  #
  # === Dock Bar Options
  #
  # +ALLOW_NOWHERE+::  Don't allow docking anywhere
  # +ALLOW_TOP+::  Docking at the top only
  # +ALLOW_BOTTOM+::  Docking at the bottom only
  # +ALLOW_LEFT+::  Docking at the left only
  # +ALLOW_RIGHT+::  Docking at the right only
  # +ALLOW_HORIZONTAL+:: Docking at the top and bottom
  # +ALLOW_VERTICAL+::  Docking at the left and right
  # +ALLOW_EVERYWHERE+:: Docking can be everywhere

    #
    # Construct a floatable dock bar, with a default parent _p_ and an
    # alternate parent _q_. To allow docking and dragging, the default parent
    # _p_ must be of type FXDockSite, and the alternate parent _q_ must be of
    # type FXToolBarShell.
    # Normally, the dock bar is docked under a window _p_ of type FXDockSite.
    # When floated, the toolbar can be docked under window _q_, which is
    # usually an kind of FXToolBarShell window.
