PERFORM_GRAPHICS_UPDATE@

Platform

Win32(ClearWin+)

Purpose

To refresh the current drawing surface display.

Syntax

SUBROUTINE PERFORM_GRAPHICS_UPDATE@( )

Description

The current drawing surface, defined by %gr, will be refreshed with every call to this routine. Under normal operations a call to a graphics function will not produce an immediate update, rather ClearWin+ will wait until you have finished your current sequence of graphics calls from within your call-back. This is not usually a problem as it ensures that only the final results are displayed.
