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: The 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: A user interface for a device is provided, wherein the user interface generates a list of elements that is too large to be displayed within a region of the UI. The number of list elements to be displayed is determined and an appropriate subset of list elements are then chosen from the generated list of elements.

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.
