NAME

       Constraint — The Constraint widget class "Constraint" "widget class" "Constraint"

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).
