Well don't get me wrong... there's a bit more to grafports than my simple explination, but I thought that kind of got the basic idea across. Yes, you can have "offscreen" grafports. You can do all your drawing to the offscreen grafport and nothing will happen on the screen. Then, later when you want it to appear on the screen, you can do a quick PPToPort to copy your offscreen port to a visible one. This is like a caching mechanism. >Robert >******************************************************************************* >* >Real: Robert Brown * Profanity is the one language all >Academic Computing Services Lab Manager * programmers know best. >Bitnet: RXBROWN@UALR * I speak for me, myself, and I!! >AOL: ROBPHD * Tires and tax not included,void where >Apple //GS the power to be your best. * prohibited.
