Hey, Gabriele, cool. Use 'across at the beginnig of your examples please, as all that
variants of scrollers don't fit 800x600 resolution.
One note to RT - I haven't seen anything so ugly as an arrow effect is, bleah :-)))) It
completly doesn't fit /View design. Just look at nice Carl's image-sort.r script, and I
can't image arrows placed anywhere on screen. At least some beveled drawing should be
used
instead of flat one for arrow effect, please :-)
Gabriele, would it be possible to get scroller which will react upon mouse relese, so
not
in real-time? I saw it implemented in some apps, and it could help us on slower
systems -
so drag the scroller, release the mouse button, do the event ...
Thanks,
