CLASS DESCRIPTION
	  The VkAlignmentGroup class provides support for aligning collections
	  of widgets with each other in various ways. To use, create an
	  instance of the VkAlignmentGroup class, add widgets or components
	  using the add() member function inherited from VkWidgetGroup, and
	  then call alignWidth(), alignHeight(), or similar functions as
	  desired.

FUNCTION DESCRIPTIONS
   VkAlignmentGroup()
	   VkAlignmentGroup(void);

	  Initializes a VkAlignmentGroup object.

   ~VkAlignmentGroup()
	   virtual void ~VkAlignmentGroup(void);

	  Frees the storage associated with a VkAlignmentGroup object. Does
	  not destroy the widgets or components contained by this object.

   add()
	   virtual void add(VkOptionMenu* menu);
	   virtual void add(Widget widget);
	   virtual void add(VkComponent component);

	  Adds widgets, components, or all the entries in a VkOptionMenu pane
	  to the group of widgets. Also see VkWidgetList::add().

   alignLeft()
	   void alignLeft(void);

	  Reposition all widgets so that all left edges align with the left
	  edge of the right-most position occupied by any widget in the group.

   alignRight()
	   void alignRight(void);

	  Reposition all widgets so that the right side of each widget is
	  moved to align with the right edge of the right-most widget in the
	  group.

   alignTop()
	   void alignTop(void);

									Page 2

VkAlignmentGroup(3x)					  VkAlignmentGroup(3x)

	  Reposition all widgets so that the top of each widget aligns with
	  the top edge of the bottom-most widget in the group.

   alignBottom()
	   void alignBottom(void);

	  Reposition all widgets so that the bottom of each widget aligns with
	  the bottom-most edge of any widget in the group.

   alignWidth()
	   void alignWidth(void);

	  Change all widgets' widths to the width of the largest widget in the
	  group.

   alignHeight()
	   void alignHeight(void);

	  Change all widgets' heights to the height of the largest widget in
	  the group.

   distributeVertical()
	   void distributeVertical(void);

	  Reposition all widgets so that they are positioned evenly in the
	  vertical direction, according to the spacing between widgets,
	  between the position of the first and last widgets in the group.

   distributeHorizontal()
	   void distributeHorizontal(void);

	  Reposition all widgets so that they are positioned evenly in the
	  horizontal direction, according to the spacing between widgets,
	  between the position of the first and last widgets in the group.

   makeNormal()
	   void makeNormal(void);

	  Return all widgets to their desired widths and heights.

   width()
	   Dimension width(void);

									Page 3

VkAlignmentGroup(3x)					  VkAlignmentGroup(3x)

	  Return the maximum width of all widgets in the group.	 This function
	  is valid only after a call to one of the alignment functions.

   height()
	   Dimension height(void);

	  Return the maximum height of all widgets in the group.  This
	  function is valid only after a call to one of the alignment
	  functions.

   x()
	   Position x(void);

	  Return the minimum x position of all widgets in the group. This
	  function is valid only after a call to one of the alignment
	  functions.

   y()
	   Position y(void);

	  Return the minimum y position of all widgets in the group.  This
	  function is valid only after a call to one of the alignment
	  functions.

INHERITED MEMBER FUNCTIONS
   Inherited from VkWidgetList
	  widgetDestroyed(), remove(), removeFirst(), removeLast(), exists(),
	  size(), operator[]()
