NAME
XtGetConstraintResourceList − get the constraint resource list structure for a particular widget class.
Synopsis
void XtGetConstraintResourceList(object_class, resources_return, num_resources_return)
WidgetClass object_class;
XtResourceList *resources_return;
Cardinal *num_resources_return;
Inputs
object_classSpecifies the object class to be queried; may be of class objectClass or any subclass thereof.
Outputs
resources_return
Returns the constraint resource list.
num_resources_return
Returns the number of entries in the constraint resource list.
Availability
Release 4 and later.
Description
XtGetConstraintResources() returns the resource list of the constraintClassPart of the widget class object_class. If it is called before the widget class is initialized, the resource list as specified in the widget class record will be returned. If it is called after the widget class has been initialized, the merged resource list for the class and all constraint superclasses is returned. If the specified object_class is not a subclass of constraintWidgetClass, *resources_return is set to NULL and *num_resources_return is set to zero. The list returned by XtGetConstraintResourceList() should be freed using XtFree() when it is no longer needed.
Usage
Most applications will never need to query a widget class for the resources it supports. This function is intended to support interface builders and applications like editres which allow the use to view the available resources and set them interactively. To get the normal resources of a widget rather than the constraint resources, use XtGetResourceList().
