<P>PROBLEM TO BE SOLVED: To allow intuitive change of overlap relations between a plurality of arranged objects. <P>SOLUTION: When two objects have an overlap without interposing other object, it is determined that the two objects are in contact with each other. The second object which has the overlap with the first object again through a non-overlap state after having the overlap with the first object is detected during movement of the first object. When it is determined that the first object and the second object are in contact with each other before and after the non-overlap state, the information processor reverses the hierarchical relation between the first object and the second object in a Z order. <P>COPYRIGHT: (C)2013,JPO&INPIT |
