Method of modifying rendered attributes of list elements in a user interface

摘要

A method of modifying attributes of list elements in a layout space of the list as the list scrolls in a user interface is disclosed herein. The method comprises determining a series of location values of each list element for a duration of a scroll event. Additionally, for each list element, at each determined location value of that list element, the attributes of that list element are determined by evaluating a set of spline curves associated with that list element based on that location value. The list elements are re-rendered in accordance with the determined attributes for the duration of the scroll event.

1. A method of modifying attributes of list elements in a layout space of a list as the list scrolls in a user interface, the method comprising:
for a duration of a scroll event, determining a series of location values of each list element, wherein a location value of a list element is based on a position of that list element in relation to a viewable portion of the list in the user interface; wherein each list element has a set of spline curves associated with it, and each spline curve defines a relationship between location values of the list element and an attribute of the list element; for each list element, at each determined location value of that list element, determining the attributes of that list element by evaluating the set of spline curves associated with that list element based on that location value; and re-rendering the list elements in accordance with the determined attributes for the duration of the scroll event.
