Abstract: Bookmarking of tokens in a set of streaming tokens, each representing an instantiation instruction or instantiation context. A navigator receives a set of streaming tokens, and provides the tokens to the instantiation manager. However, if the navigator receives an instruction to bookmark a particular token, the navigator buffers the set of streaming instructions at least beginning at the bookmarked token (and possible even earlier if there were prior bookmarks). The navigator replays the set of streaming tokens beginning at a bookmark in response to an instruction from an instantiation manager. The instantiation manager receives the set of streaming tokens. If the instantiation manager is not presently capable of handling the instruction of a particular token, the instantiation manager instructs the navigator to bookmark the particular token.

Abstract: Digital shadowing when rendering visual items (e.g., windows) at different virtual display levels (such as z-order levels). The rendering is based on the determination of a position and virtual display level for each of the visual items to be displayed. For those visual items that cast a shadow on lower-level in-shadow visual items, the determined position of the shadow-casting visual item is used to render the shadow on each of the in-shadow visual items differently depending on the corresponding virtual display level of the in-shadow visual items. In particular, the in-shadow visual item that has a lower virtual display level has a longer shadow cast by the shadow-casting visual item than those in-shadow visual items that have a higher virtual display level. This allows the shadows to have a more natural look.

Abstract: An application work area that includes a splitting mechanism that permits the work area to be divided into multiple windows. Each window is capable of displaying a selected object of the available objects that are open in the application. Each window might include a corresponding distinct object selection mechanism that allows a user to select one of the open objects to display in the corresponding window. In one embodiment, this is permitted regardless of whether that open object is already displayed in another of the windows. As examples, the object selection mechanism may be a selectively viewable open object list such as, for example, a drop down list. Thus, each window that has an object selection mechanism may be used to independently control the object that is viewed in that window.

Abstract: An improved system and method for displaying a user interface object using an associated style is provided. To this end, an application may include style declarations that may associate a style resource with a user interface object. The style resource may define property values that may be selectively applied to a user interface object, may specify a visual representation for the user interface object, such as a visual subtree, and may specify additional property values to be conditionally applied to a user interface object. A styling engine may be provided for applying a style resource to a user interface object. A visual representation of the user interface objects with the applied property values may be generated and then a display representation may be rendered for presentation on a user interface display.
