Abstract

A system for dynamically adapting a presentation generated with a scalable application to a display screen of any of a plurality of heterogeneous device platforms is disclosed. The system includes a device platform and a transformation module. The device platform is one of the heterogeneous device platforms and includes a display screen. The device platform is operable to initiate generation of a hierarchical configuration representing a plurality of graphical user interface components. The transformation module is operable to selectively arrange the graphical user interface components on a page as a function of the hierarchical configuration. In the addition, the transformation module is operable to selectively transform the graphical user interface components to maximize the fill of the display screen by the page.

Claims

1. A method of dynamically adapting a presentation generated by a scaleable application to a display screen of any of a plurality of heterogeneous device platforms, the method comprising:

a) providing a plurality of graphical user interface components in a hierarchal configuration;

b) arranging the graphical user interface components on a page as a function of the hierarchy; and

c) selectively transforming the graphical user interface components to adjust the size of the page to maximize the fill of a display screen of one of the heterogeneous device platforms on which the scaleable application is operating.

2. The method of claim 1, wherein b) comprises identifying graphical user interface components representative of the lowest hierarchical level and a highest layout priority within the hierarchical configuration.

3. The method of claim 1, wherein c) comprises reducing the size of the graphical user interface components as a function of transformation rules when the display screen is over-filled by the page.

4. The method of claim 1, wherein c) comprises selecting alternative graphical user interface components as a function of transformation rules when the display screen is over-filled by the page.

5. The method of claim 1, wherein c) comprises adding graphical user interface components to the page as a function of the hierarchical configuration when the display screen is under-filled by the page.

6. The method of claim 1, wherein c) comprises repeating a), b) and c) to generate another page with the remaining graphical user interface components when the page substantially fills the display screen.

7. The method of claim 1, wherein b) comprises applying a set of style guide parameters to each of the graphical user interface components to create uniformity in the visual appearance of the graphical user interface components.

8. The method of claim 1, wherein b) comprises arranging the graphical user interface components as a function of properties specified by the scaleable application.

9. The method of claim 1, wherein c) comprises:

generating a set of proposed device platform specific pages; and

selecting at least one device platform specific page from the set to display the graphical user interface components with the display screen.

10. The method of claim 9, wherein generating a set of proposed device platform specific pages comprises sizing each of the proposed device platform specific pages as a function of the graphical user interface components arranged to form each of the proposed device platform specific pages.

11. A method of dynamically adapting a presentation generated by a scaleable application to a display screen of any of a plurality of heterogeneous device platforms, the method comprising:

a) providing an intermediate representation comprising a plurality of container nodes in a hierarchical configuration;

b) identifying a first container node with the lowest hierarchal level and the highest layout priority in the intermediate representation;

c) arranging on a page at least one graphical user interface component associated with the first container node;

d) applying a transformation rule to reduce the size of the at least one graphical user interface component when the page over fills a display screen of one of the heterogeneous device platforms; and

e) adding at least one graphical user interface component from a hierarchically related container node when the page under fills the display screen.

12. The method of claim 11, wherein d) comprises selecting an appropriate transformation rule as a function of at least one of the at least one graphical user interface component and capabilities of said one of the heterogeneous device platforms.

13. The method of claim 11, wherein the transformation rule is applied as a function of a ranking indicating the degree of general applicability of the transformation rule to said one of the heterogeneous device platforms.

14. The method of claim 11, wherein applying the transformation rule comprises:

generating a list of possible graphical user interface components sorted by size;

selecting a graphical user interface component from the list; and

interchanging the at least one graphical user interface component arrange on the page in c) with the graphical user interface component from the list.

15. The method of claim 11, wherein d) comprises transforming a graphical user interface component to a graphical user interface component that is specific to said one of the heterogeneous device platforms.

16. The method of claim 11, wherein d) comprises transforming a composite graphical user interface component comprising a plurality of graphical user interface components associated with a container node to a composite graphical user interface component specific to said one of the heterogeneous device platforms.

17. The method of claim 11, wherein e) comprises selecting a container node that is one of a hierarchical sibling or a related higher level container node.

18. The method of claim 11, wherein e) comprises repeating d).

19. The method of claim 11, wherein b) comprises identifying a container node with at least one graphical user interface component as a hierarchical child.
