NAME
     VkPrefGroup - Grouping interface for preference package

INHERITS FROM
     VkPrefItem : VkComponent : VkCallbackObject

HEADER FILE
     #include <Vk/VkPrefItem.h>

PUBLIC PROTOCOL SUMMARY
   Constructor/Destructor
	   VkPrefGroup(const char* name,
		       Boolean horizOrientation = False,
		       Boolean noLabel = False);
	   virtual void ~VkPrefGroup(void);

   Adding Items
	   void addItem(VkPrefItem* item);

   Access Functions
	   int size(void);
	   VkPrefItem* item(int which);

CLASS DESCRIPTION
     VkPrefGroup groups preference objects together.  It enforces an
     arrangement policy that creates "standard" appearances among different
     preference dialogs.  Vertically-oriented groups (the default) left-align
     the object labels.	 Horizontally-oriented groups throw away the object
     labels, and arrange the object base widgets in a row.

FUNCTION DESCRIPTIONS
   VkPrefGroup()
	   VkPrefGroup(const char* name,
		      Boolean horizOrientation = False,
		      Boolean noLabel = False);
	   virtual void ~VkPrefGroup(void);

	  Create a group preference object.  The second argument turns on
	  horizontal orientation, and the third argument turns off the label
	  widget for the group itself.

   addItem()

									Page 1

VkPrefGroup(3x)						       VkPrefGroup(3x)

	   void addItem(VkPrefItem* item);

	  Adds a preference object to the group.  The new item is added to the
	  end of the list, so appears at the end of the arrangement.

	  Note that when you use addItem, the new item takes on the activated
	  or deactivated state of the group.  Therefore, you should activate
	  or deactivate an item after you add it to a group with addItem.

   size()
	  int size(void);

	  Returns the number of items in the group.

   item()
	  VkPrefItem* item(int which);

	  Returns a specific item from the group.
