HI all, I am a little confused about the nature of the scroll view. The confusion of course comes from ignorance about the behavior of the scroll view. Anyway, I am wondering just how a scroll view works. For example, in digital librarian you type in a search and get a bunch of icons below with the results. Usually the list is more then a screen full, so you have to use the scroller. What I am wondering is if DL actually has to recalculate and redraw the scroll view each time it is scrolled. Or, is there some tricky way to do it so that the scroll view actually does the recalculated and what not. I guess what it comes down to is, if I want scrollable graphics, do I need to overwrite the drawself with some code to calculate what should be redrawn in the doc view of the scroll view? I hope that I haven't been to general in my question, but any input would be great. Thanks in advance, -- -Scott Violet (xepo@csd4.csd.uwm.edu)
