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:
+o Overall management of children from creation to
destruction.
+o Destruction of descendants when the composite widget is
destroyed.
+o Physical arrangement (geometry management) of a
displayable subset of managed children.
+o 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.

Composite inherits behavior and resources from CCCCoooorrrreeee.
The class pointer is ccccoooommmmppppoooossssiiiitttteeeeWWWWiiiiddddggggeeeettttCCCCllllaaaassssssss.
The class name is CCCCoooommmmppppoooossssiiiitttteeee.

The following table defines a set of widget resources used
by the programmer to specify data. The programmer can also
set the resource values 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 XXXXmmmmNNNN or XXXXmmmmCCCC
prefix and use the remaining letters. To specify one of the
defined values for a resource in a .Xdefaults file, remove
the XXXXmmmm prefix and use the remaining letters (in either
lowercase or uppercase, but include any underscores between

XXXXmmmmNNNNcccchhhhiiiillllddddrrrreeeennnn
A read-only list of the children of the widget.

Points to the XXXXttttOOOOrrrrddddeeeerrrrPPPPrrrroooocccc function described
below.

A read-only resource specifying the length of the
list of children in XXXXmmmmNNNNcccchhhhiiiillllddddrrrreeeennnn.
The following procedure pointer in a composite widget
instance is of type XXXXttttOOOOrrrrddddeeeerrrrPPPPrrrroooocccc:

WWWWiiiiddddggggeeeetttt _w;
_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 composite 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
_z_e_r_o 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.

Composite inherits behavior and resources from the following
superclass. For a complete description of each resource,
refer to the manual page for that superclass.
