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).
