Abstract: 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.

Abstract: A method of determining a layout of a user interface (UI) that composites elements from a plurality of applications, each of the plurality of applications having a respective UI client engine, the method comprising: receiving, from one of a plurality of UI client engines, a request to change layout parameters; negotiating, between the plurality of UI client engines, changes to the layout parameters to determine negotiated layout parameters; and transmitting the negotiated layout parameters to a UI rendering engine, as a component tree structure, for rendering to a display. A UI system, electronic device and computer program product are also provided.
