NAME
       Constraint — The Constraint widget class

SYNOPSIS
       #include <Xm/Xm.h>

DESCRIPTION
       Constraint widgets maintain additional state data for each child. For
       example, client-defined constraints on the child's geometry may be
       specified.

       When a constrained composite widget defines constraint resources, all
       of that widget's children inherit all of those resources as their own.
       These constraint resources are set and read just the same as any other
       resources defined for the child. This resource inheritance extends
       exactly one generation down, which means only the first-generation
       children of a constrained composite widget inherit the parent widget's
       constraint resources.

       Because constraint resources are defined by the parent widgets and not
       the children, the child widgets never directly use the constraint
       resource data. Instead, the parents use constraint resource data to
       attach child-specific data to children.

   Classes
       Constraint inherits behavior and resources from Composite and Core.

       The class pointer is constraintWidgetClass.

       The class name is Constraint.

   New Resources
       Constraint defines no new resources.

   Inherited Resources
       Constraint inherits behavior and resources from Composite and Core.
       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).
