Touch display scroll control

摘要

A scroll control recognizes a touch input directed to a selectable item while the selectable item is scrolling on a touch display. The scroll control determines if the selectable item is scrolling above a threshold velocity when the touch input directed to the selectable item is recognized. If the selectable item is determined to be scrolling above the threshold velocity, scrolling of the selectable item is stopped. If the selectable item is determined to be scrolling below the threshold velocity, the selectable item is selected.
