The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

SET PICK MODE (PHOP,WSOP,*,*)

Purpose

Use Set Pick Mode to set the operating mode of the specified pick device.

After the pick mode is set, the graPHIGS API sets the echoing state to ECHO or NOECHO. Depending on the specified operating mode--Request, Sample, or Event-- an interaction with the given device may begin or end.

Note:

The graPHIGS API resets the input device with the initialization values when your application calls the Description subroutine with the operating mode parameter set to SAMPLE or EVENT.
