METHOD AND SYSTEM FOR FOCUS MANAGEMENT IN A SOFTWARE APPLICATION

摘要

A method for focus management in a software application, wherein at least a subset of Node objects of said software application forms a hierarchy of Node objects and wherein each Node object of said hierarchy of Node objects of said software application comprises: a first routine that when returning true denotes that the Node object is a focused one; and a second routine that when returning true denotes that the Node object is a focused, or at least one of its descendants is a focused; a routine for handling an incoming event; the method comprising the steps of: providing, for each Node object of said hierarchy of Node objects a third routine, that when returning true denotes that the Node object and all descendants of the Node object, excluding these Node objects for which the third routine returns true, forms a single monofocus area having a single focus root.

1. A method for focus management in a software application, wherein at least a subset of Node objects of said software application forms a hierarchy of Node objects and wherein each Node object of said hierarchy of Node objects of said software application comprises:
a first routine (1405) that when returning true denotes that the Node object is a focused one; and a second routine(1407) that when returning true denotes that the Node object is a focused, or at least one of its descendants is a focused; a routine for handling an incoming event;wherein the method comprises the steps of:
providing, for each Node object of said hierarchy of Node objects a third routine (1406), that when returning true denotes that the Node object and all descendants of the Node object, excluding these Node objects for which the third routine returns true, forms a single monofocus area (805, 907, 909) having a single focus root.
