NAME

DvInqDefinitionGroup − Return the definition group for a view

SYNOPSIS

C:

DtObject DvInqDefinitionGroup(view)
DtObject view;

FORTRAN:

INTEGER∗4 DVQDG(VIEW)
INTEGER∗4 VIEW

DESCRIPTION

DvInqDefinitionGroup returns the handle for a definition group of the view specified by the parameter view.  The definition group is the part of every view that contains the objects that define the studio objects.  During the definition group traversal of a view update, all objects in the definition group are executed sequentially.  Users may edit the definition group to arrange objects in the desired order of execution.  The objects in a view’s definition group may be any of the studio objects, studio attribute objects, or other groups of the same.  Objects that are not studio object types are ignored during definition traversal. 

ERRORS

DvInqDefinitionGroup will fail if the view handle is invalid; the returned value is DcNullObject <DCNULL>. 

[WARNING - invalid view handle]
