I'm working on the Adobe Labs Scheduling Framework. The "main
component" is based on the ScrollControlBase class. My problem is
now, that by using the mouse-wheel a negative value for the
vertical scroll position is possible. I allready "fixed" it by
catching the scroll event, checking for a value less then zero and
if so setting it to zero.
But it still scrolls a little bit into the negative area and
it just doesn't look/feel good because there is a certain dealy
until it is set back to zero.
Is it possible to prevent negative scroll positions? I
couldn't find any properties, but my tests with for example a
canvas showed that this component prevents it.
