Page designer with customization constraints

摘要

A page design system addresses the need to impart flexibility into the design and customization of graphical user interfaces for applications. The graphical user interface includes pages and display groups within each page, and the page design system permits each individual page to be modified to suit the needs of a particular customer. So that the pages do not depart from their fundamental purpose to too great of an extent, the page design system guides and constrains the modifications to each page. In particular, the page design system constrains customization of each display group according to established definitions of admissible graphical user interface elements that are appropriate for each page, and each display group of elements within the page.
