VIEW VIRTUALIZATION

摘要

The described technology is directed towards having UI elements structured in a hierarchical configuration, in which parent and child UI elements communicate via a virtualization interface. A change to any parent UI element view propagates to each impacted descendant, e.g., each child, any children of that child and so on, whereby each child can manage virtualization and rendering based upon the change. Focus changes among the UI elements are also handled by propagating information via the virtualization interface.

1. A method comprising:
rendering a view corresponding to a parent user interface (UI) element, the view including at least one child UI element of the parent UI element; receiving a change to the view; determining which child UI element or children UI elements of the parent UI element are relevant based upon the change to the view, and creating any non-instantiated child UI element that is relevant; determining which child UI element or children UI elements of the parent UI element are not relevant based upon the change to the view, and virtualizing away at least one child UI element that is not relevant; propagating data corresponding to the change to the view to each relevant child UI element of the parent UI element; and rendering a new view corresponding to the parent UI element, the new view including one or more relevant child UI elements of the parent UI element.
