[comp.sys.mac.programmer] flicker-free text

rla@julius.uucp (Richard L. Altman) (08/02/89)

	I am working on a program that diplays characters to the screen 
at a very rapid pace.  For lack of knowing a better way to write 
quickly to the screen, I deactiavted the text, and SetSelect-ed and 
TEPaste-d everything instead of calling TEUpdate every time the
screen had to be changed.  The only bad thing about this is that there
is a very annoying screen flicker that occurs periodically as the 
screen changes.  I guess that it doesn't refresh during the 
vertical retrace as it should, but A) I am not very familiar w/the 
VerticalRetrace functions, and B) I hope deep in my mind that there 
is a better way to achieve my goal.   Could someone please clue me
in to a better toolbox call or post (or E-mail) some good code as an
example of the Vertical Retrace functions.  Thanks.
