GPVCH - Set View Characteristics
| GPVCH
(wsid,
view,
window,
near,
far,
shield,
shldci,
border,
brdrci,
active) |
Purpose
Use
GPVCH
to set the characteristics of the specified view.
These
characteristics include:
clipping indicators, appearance of the
viewport, and a value indicating
whether or not the view is displayed.
The values specified are stored in the requested view table
entries.
The corresponding current values in the view table entry are
set to the requested values when the workstation is updated.
The clipping indicators determine to which boundaries the
contents of the view are clipped.
The shielding indicator
determines whether the content of lower priority views may be
displayed within the boundaries of the specified view.
The border indicator and color specify whether a border is to be
drawn around the viewport, and if it is, its color.
The view active flag determines whether the view and its contents
are displayed.
