NAME

       Composite — The Composite widget class "Composite" "widget class" "Composite"

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 creation 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  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  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).
