In my application I have a applicationControlBar at the top of the
screen and a space to load different modules below. In a module that
needs a faster scroll speed, I add an event listener in the init
handler...
private function onInit():void
{
addEventListener(MouseEvent.MOUSE_WHEEL,
onMouseWheelEvent);
}
Then the code posted previously is called whenever a
MouseEvent.MOUSE_WHEEL event occurs. This works great and my users love
it.
Flex generally has a delta of +5 and -5 depending on direction of the
mousewheel. The code either adds or subtracts fifty depending on the
direction so the delta will now be either -55 or +55 which is a much
larger jump than 5.
HTH.
