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).
