Picking tagged primitives
- GSTAG
- Sets a tag value for following primitives.
Initializing logical devices
- GSENAB
- Enables and disables a logical input device.
- GSILOC
- Initializes a locator input device and defines the echo that is
seen on the screen.
- GSIPIK
- Initializes a pick input device and defines the echo that is seen
on the screen.
- GSISTK
- Initializes a stroke input device and defines the echo that is seen
on the screen.
- GSISTR
- Initializes a string input device and defines the echo that is seen
on the screen.
- GSIDVF
- Sets an initial floating-point data value. For a locator device,
this value is a coordinate for the initial positioning of the
locator echo. For a pick device, this value is the pick aperture.
- GSIDVI
- Sets an initial integer data value. For a locator device, this
value is the segment identifier to used for the locator echo. For
a string device, this value is the initial cursor position.
Input and output functions
- GSREAD
- Updates the graphics screen, waits for, and returns graphics input.
- GSFLSH
- Clears all items from the graphics input queue.
Interactive graphics query functions
- GSCORS
- Queries (correlates) segment and tag information for the structure
of each tagged primitive in the current graphics field that
intersects a defined aperture.
- GSQCHO
- Returns choice data from the current input record presented by the
GSREAD call.
- GSQLID
- Returns information about a specified logical input device.
- GSQLOC
- Returns locator data from the current input record presented by the
GSREAD call.
- GSQPIK
- Returns pick data from the current input record presented by the
GSREAD call.
- GSQPKS
- Returns the pick structure data from the current input record
presented by the GSREAD call.
- GSQSIM
- Returns whether the next record to be returned by the GSREAD call
from the graphics input queue was produced by the same terminal
operator action as the current record.
- GSQSTK
- Returns stroke data from the current input record.
- GSQSTR
- Returns string data from the current input record.
- GSQTAG
- Returns the current tag value as set by the most recent GSTAG call.
