NAME
Constraint - the Constraint widget class.
AES SUPPORT LEVEL
full-use
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. Constraint
resource date is instead used by the parents 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
lower case or upper case, 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).
