  #
  # The FXTabBar layout manager arranges tab items side by side,
  # and raises the active tab item above the neighboring tab items.
  # In a the horizontal arrangement, the tab bar can have the tab
  # items on the top or on the bottom.  In the vertical arrangement,
  # the tabs can be on the left or on the right.
  # When one of the tab items is pressed, the tab bar's #setCurrent()
  # method is called with _notify_ of +true+. This in turn causes the tab bar
  # to send a +SEL_COMMAND+ message to its target.
  #
  # === Events
  #
  # The following messages are sent by FXTabBar to its target:
  #
  # +SEL_COMMAND+::
  #   sent whenever the current tab item changes;
  #   the message data is an integer indicating the new current tab item's index.
  #
  # === Tab book options
  #
  # +TABBOOK_TOPTABS+::		Tabs on top (default)
  # +TABBOOK_BOTTOMTABS+::	Tabs on bottom
  # +TABBOOK_SIDEWAYS+::	Tabs on left
  # +TABBOOK_LEFTTABS+::	Tabs on left
  # +TABBOOK_RIGHTTABS+::	Tabs on right
  # +TABBOOK_NORMAL+::		same as <tt>TABBOOK_TOPTABS</tt>
