- 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,
- --
