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).
