User interface rendering component environment

摘要

A client software program for use with an embedded device includes an application layer, a programming environment configured to render user interface component areas and query user interface component extensions from a shared delegation object, and an operating system layer. A drawing is preferably split up into a non-overridable system part and an overridable user part. The user interface component data and data used to factorize the way it is rendered are logically separated.
