Hi,
When you have a database with millions of records, it's not possible
to display everything in a scrollview because it would be too slow. A
better way would be to use a scrollbar, when the user is clicking on
the "1 line down arrow", we just need to fetch one more row and to
display what should be displayed.
But I read and read again everything about nsscroller and I don't
understand how to create a simple scroller, just to retreive clicks
and relative position. When I'm trying to put a customview with IB,
changing its type to nsscroller, connecting it to an outlet, I don't
understand how to set the values so that it will be displayed with
thumb and arrows, I tried many things but I always have an emply
scrollbar.
Shall I call something so that it will appear correctly??
many thanks for any suggestion and help about such a problem!
