6 Constraint — The Constraint widget class

9 #include <Xm/Xm.h>
10
12 Constraint widgets maintain additional state data for each child. For
13 example, client-defined constraints on the child's geometry may be
14 specified.
15 When a constrained composite widget defines constraint resources, all
17 of that widget's children inherit all of those resources as their own.
18 These constraint resources are set and read just the same as any other
19 resources defined for the child. This resource inheritance extends
20 exactly one generation down, which means only the first-generation
21 children of a constrained composite widget inherit the parent widget's
22 constraint resources.
23 Because constraint resources are defined by the parent widgets and not
25 the children, the child widgets never directly use the constraint
26 resource data. Instead, the parents use constraint resource data to
27 attach child-specific data to children.
28 Classes
30 Constraint inherits behavior and resources from Composite and Core.
31 The class pointer is constraintWidgetClass.
33 The class name is Constraint.
35 New Resources
37 Constraint defines no new resources.
38 Inherited Resources
40 Constraint inherits behavior and resources from Composite and Core.
41 The following table defines a set of widget resources used by the pro‐
42 grammer to specify data. The programmer can also set the resource val‐
43 ues for the inherited classes to set attributes for this widget. To
44 reference a resource by name or by class in a .Xdefaults file, remove
45 the XmN or XmC prefix and use the remaining letters. To specify one of
46 the defined values for a resource in a .Xdefaults file, remove the Xm
47 prefix and use the remaining letters (in either lowercase or uppercase,
48 but include any underscores between words). The codes in the access
49 column indicate if the given resource can be set at creation time (C),
50 set by using XtSetValues (S), retrieved by using XtGetValues (G), or is
51 not applicable (N/A).
