Purpose |
To refresh the current drawing surface display. |
|
Syntax |
SUBROUTINE PERFORM_GRAPHICS_UPDATE@( ) |
|
Description |
The current drawing surface, defined by %gr (Graphics Region), 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. |
