SYSTEM property which disables (when set to 1) or enables (when set to 0, the default) the feature where all window re-painting is completely done before processing continues with the next statement following a DISPLAY. Setting PROP:LazyDisplay = 1 creates seemingly faster video processing, since the re-paints occur at the end of the ACCEPT loop if there are no other messages pending. This can improve the performance of some applications, but can also have a negative impact on appearance.

Example:

WinView   APPLICATION('MyApp'),AT(0,0,320,200),MAX,HVSCROLL,SYSTEM

     END

CODE

OPEN(WinView)

SYSTEM{PROP:LazyDisplay} = 1   !Disable extra paint message display

                ! throughout entire application

ACCEPT

END
