TrinaGridScrollUpdateEvent class

An event that occurs when dragging or moving after a long tap.

When the offset enters the area that needs to be scrolled, the scroll animation continues until the end of the scroll direction.

When scrolling animation is in progress and entering an area that does not require scrolling, the existing scroll animation is stopped.

If a point up event occurs while scroll animation is in progress, the caller calling this event must call TrinaGridScrollUpdateEvent.stopScroll to stop the animation.
