As noted by Sun, a MouseWheelListener is added to the BasicScrollPaneUI.
Alternative input-devices (read: not mice) like touchpads often also actively
support scrolling. This should work in Java as good as in native apps. In the
case of my touchpad I can slide a horizontal or vertical edge and my window
will scroll: Very convenient and intuitive. It seems likely to me that this
done by it's device-driver sending scrolling events to the targeted native
window. Aren't these events catchable by the underlying Swing-components? I can
imagine that this would be regular native scrolling-events which could be
transformed to 'special AWT events' and from there be adapted as Java Swing
scrolling-events.
The native device-drivers have already done the job of transforming the lower
level device-events to higher-level scrolling events of the native GUI. It
seems to me that all that rests is to get those events into the Java event
system. It's only a quick think-over, but a solution seems very important to
me. People expect these features..
