NAME
       Composite - The Composite widget class

SYNOPSIS
       #include <Xm/Xm.h>

DESCRIPTION
       Composite  widgets  are intended to be containers for other widgets and
       can have an  arbitrary  number  of  children.   Their  responsibilities
       (implemented  either  directly  by  the	widget	class or indirectly by
       Intrinsics functions) include: Overall management of children from cre‐
       ation  to  destruction.	 Destruction of descendants when the composite
       widget is destroyed.  Physical arrangement (geometry management)	 of  a
       displayable  subset  of	managed	 children.  Mapping and unmapping of a
       subset of the managed children.	Instances of composite widgets need to
       specify	the  order  in which their children are kept.  For example, an
       application may want a set of command buttons  in  some	logical	 order
       grouped	by  function, and it may want buttons that represent filenames
       to be kept in alphabetical order.

   Classes
       Composite inherits behavior and resources from Core.

       The class pointer is compositeWidgetClass.

       The class name is Composite.

   New Resources
       The following table defines a set of widget resources used by the  pro‐
       grammer to specify data.	 The programmer can also set the resource val‐
       ues for the inherited classes to set attributes for  this  widget.   To
       reference  a  resource by name or by class in a .Xdefaults file, remove
       the XmN or XmC prefix and use the remaining letters.  To specify one of
       the  defined  values for a resource in a .Xdefaults file, remove the Xm
       prefix and use the remaining letters (in either lowercase or uppercase,
       but  include  any  underscores between words).  The codes in the access
       column indicate if the given resource can be set at creation time  (C),
       set by using XtSetValues (S), retrieved by using XtGetValues (G), or is
       not applicable (N/A).

			       Composite Resource Set
		──────────────────────────────────────────────────────
		Name			  Default	       Access
		      Class			Type
		──────────────────────────────────────────────────────
		──────────────────────────────────────────────────────
		XmNchildren		  NULL		       G
		      XmCReadOnly		 WidgetList
		──────────────────────────────────────────────────────
		XmNinsertPosition	  NULL		       CSG
		      XmCInsertPosition		 XtOrderProc
		──────────────────────────────────────────────────────
		XmNnumChildren		  0		       G
		      XmCReadOnly		 Cardinal
		──────────────────────────────────────────────────────
       A read-only list of the children of the widget.	Points to the XtOrder‐
       Proc  function  described  below.   A read-only resource specifying the
       length of the list of children in XmNchildren.

       The following procedure pointer in a composite widget  instance	is  of
       type  XtOrderProc:  Cardinal (* XtOrderProc) (widget)	  Widget    w;
       Specifies the widget.

       Composite widgets that allow clients to order their  children  (usually
       homogeneous  boxes)  can	 call  their widget instance's insert_position
       procedure from the class's insert_child procedure to determine where  a
       new child should go in its children array.  Thus, a client of a compos‐
       ite class can apply different sorting criteria to widget	 instances  of
       the  class,  passing  in	 a different insert_position procedure when it
       creates each composite widget instance.

       The return value of the insert_position procedure  indicates  how  many
       children	 should	 go  before the widget.	 Returning zero indicates that
       the widget should go before all other children; returning  num_children
       indicates  that	it  should  go	after all other children.  The default
       insert_position function returns num_children and can be overridden  by
       a  specific  composite  widget's	 resource list or by the argument list
       provided when the composite widget is created.

   Inherited Resources
       Composite inherits behavior and resources  from	the  following	super‐
       class.	For a complete description of each resource, refer to the man‐
       ual page for that superclass.
