- I am writing an application were I need scrollable list boxes in dialog
- boxes (eg. like the file selector list). Rather than write my own I was
- wondering whether anybody has any code already written to do this? Failing
- that what is the best strategy for writing a scrollable list? I have worked
- out that in order to make the scrolling fast and smooth I need to do some
- blitting, i.e.\ blit n-1 of the entries (n=no of items in scroll window)
- and write out the new line either at the top or bottom of the
- list. And what is the best strategy to write a smooth moving slider which
- will sit next to the list box? I have managed to write a relatively
- smooth moving slider but it's not perfect.
-
- Once I've written it I'll send the source to a.a
