NAME

DoPickID − Create a pick identifier object

SYNOPSIS

C:

DtObject DoPickID(pickid)
DtInt pickid;

FORTRAN:

INTEGER∗4 DOPID(PICKID)
INTEGER∗4 PICKID

DESCRIPTION

DoPickID returns a pick identifier primitive attribute object. The argument pickid determines the pick identification number for subsequent objects.  A pick identification number is an arbitrary 32-bit value that is used to identify various parts of the Dor´
e  database. It is similar to a name set in its ability to identify or give special meaning to parts of the database.

The pick identifiers are part of the information returned in a pick.  They are returned for the picked primitives as well as for their ancestors in the hierarchy. 

DEFAULTS

The default DoPickID is 0.
