Abstract: A virtual file system is described that enables both real data resources, such as a content file, and virtual data resources, such as a field within a database or a state determined by a mark-up language element, to be accessed through a single root.

Abstract: The present invention relates to a method for displaying moving items in a user interface and, in particular, to such a method for use within a device for use with a wireless communications network. The invention provides a method and apparatus for displaying a moving object in which the object is part of a user interface defined by a mark-up language and in which the movement of the object is defined by an arbitrary profile.

Abstract: A method of generating displayable content is provided. The method includes obtaining a display package having a plurality of display elements defining a plurality of display frames. The method further includes rendering at least one selected group of the plurality of display elements. Each selected group is based on indicator information in the display package and comprises less than all of the plurality of display elements. Further included is saving a copy of each rendered selected group in a second display buffer. The method further includes rendering at least one display frame within the plurality of display frames such that at least a portion of the at least one rendered display frame comprises the saved copy of at least one rendered selected group. Further included is saving the at least one rendered display frame in a first display buffer that is different from the second display buffer.

Abstract: Described are various methods and apparatuses for fine grained control of z-order elements in a presentation. A structure is defined containing user interface elements and an order is defined for rendering such user interface elements. It is desired that some elements may need to be rendered out of the defined order, therefore a raise user interface element is defined allowing for one or more user interface elements to be defined to be rendered out of the normally defined order. User interface elements may something to be presented on a display and may also include program code for defining behaviors.

Abstract: There is provided a user interface which is defined by a plurality of actors and the attributes) that are associated with the actors. A renderer is used to render the user interface in accordance with the attributes of the actors. Changes in actor attributes, for example in response to a keypress, cause the user interface to be updated.
