- Sub: RE: Infinite Scroller
-
- James,
-
- I don't think you'll ever be able to implement a truly "infinite" scroller
- on a digital machine. It seems to me that there must be some way for you to
- decide upon some limits for your scroller. As it stands, MacApp can handle
- Scroller values in the range of -2147483647 thru 2147483647. If this is not a
- large enough range, you should be able to implement a larger one in much the
- same way that LONGINT scroll values were handled in MacApp by Overriding the
- pertinent methods ((G,S)etLongMax, (G,S)etLongMin, (G,S)etLongVal,
- SetScrollLimits, etc...) using REAL or EXTENDED Types. I'm not looking at code
- right now, but I'm under the impression that you may end up doing more
- "rewriting" than "Overriding".
-
- Although, left/right arrows (ala HyperCard) probably aren't the solution
- you're looking for, Alan may be on the right track as far as recommending
- something other than scrollbars...
-
- Let us all know what you come up with, it might be useful to others.
-
-
- Good Luck,
