I need to extract all elements visible inside a scrolling panel. I have a long list of elements inside, and their positions respectively to the scrolling panel. I wish to retrieve all elements visible in O(1). I wondered what data structure I should use to store the list of elements, all I know is their relative positions inside the scrolling panel {top, bottom, left, right}.

code is in java (GWT for wep app)
