NAME

DfInqViewGroup − Return the handle for a frame’s view group

SYNOPSIS

C:

DtObject DfInqViewGroup(frame)
DtObject frame;

FORTRAN:

INTEGER∗4 DFQVG(FRAME)
INTEGER∗4 FRAME

DESCRIPTION

DfInqViewGroup returns the handle for a frame’s view group.  The view group is part of every frame and contains the view handles of all the views associated with the frame (see DoView).  When the frame is updated, all views in its view group are updated in order and all non-view objects found in its view group are ignored. 

ERRORS

DfInqViewGroup will fail if the frame handle is invalid; DcNullObject <DCNULL> is returned. 

[WARNING - invalid frame handle]
