Abstract

A computing system provided according to an aspect of the present invention contains a server system operable to send a same hierarchical menu to client systems which display the sub-menus of the hierarchical menu in a overlapping style or a cascading style. As a result, the implementation of server systems supporting such client systems may be simplified. According to another aspect, an event handler is also implemented on the server system, to process the events generated by client system displaying menus in both the overlapping style and the cascading style. According to yet another aspect, a server system stores a in-memory representation of a context menu, and thereafter serves requests from different clients for the same hierarchical menu based on such in-memory representation.

Claims

1. A computing system comprising:

a server system operable to send a context menu associated with a first graphical element, said context menu containing a first sub-menu and a second sub-menu, wherein said second sub-menu is represented as a child of a parent menu item contained in said first sub-menu;

a first client system to receive said context menu associated with said first graphical element, and display said first sub-menu and said second sub-menu in an overlapping style on a first display unit associated with said first client system, wherein said context menu is displayed in a first display area on said first display unit; and

a second client system to also receive said context menu associated with said first graphical element, and then display said first sub-menu and said second sub-menu in a cascaded style on a second display unit associated with said second client system, wherein said context menu is displayed in a second display area on said second display unit, wherein said first display area is smaller than said second display area,

wherein said second sub-menu is displayed upon selection of said parent menu item in each of said first client system and said second client system,

wherein said first sub-menu and said second sub-menu are displayed in said cascading style in said first client system in view of said first display area being smaller than said second display area.

2. The computing system of claim 1, wherein each of said first client system and said second client system displays a corresponding web page containing said first graphical element,

each of said first client system and said second client system displaying said first sub-menu upon a first user action with respect to said first graphical element displayed on the corresponding web page,

wherein said selection is performed based on said displaying of said first sub-menu.

3. The computing system of claim 2, wherein said context menu is provided by said server system to each of said first client system and said second client system within said corresponding web page, wherein said corresponding web page sent by said server system contains data representing said context menu.

4. The computing system of claim 2, wherein said first client system receives said first user action with respect to said first graphical element displayed in said corresponding web page, and in response communicates with said server system to indicate that said first user action has been performed with respect to said first graphical element, and receives said context menu asynchronously as a response from said server system.

5. The computing system of claim 2, wherein said first user action from each of said first client system and said second client system invokes a single event handler executing in said server system.

6. The computing system of claim 2, wherein said first sub-menu contains a first set of menu items and said second sub-menu contains a second set of menu item,

wherein each of said first set of menu items are available for selection in said second client system when said second set of menu items are displayed on said second display unit,

wherein said first set of menu items are unavailable for selection in said first client system when said second set of menu items are displayed on said first display unit.

7. The computing system of claim 2, wherein said server system is operable to:

maintain an in-memory representation of said context menu in a volatile memory;

receive a third request for a context menu for said graphical element;

retrieving said context menu from said volatile memory, in response to said receiving of said third request, wherein said in-memory representation is present in said volatile memory before receiving of said third request;

sending said context menu as a response to said third request.

8. The computing system of claim 7, wherein said server system is further operable to:

receive a fourth request from a second user;

in response to receiving said fourth request;

retrieving said context menu from said volatile memory;

sending the retrieved context menu to an external security server, which applies a second set of filters applicable to said second user, to generate a filtered context menu;

receiving said filtered context menu and sending the received filtered context menu as a response to said fourth request,

whereby said context menu is retrieved only once from a data store in processing multiple requests received from different users.

9. The computing system of claim 1, wherein said first display unit has a smaller display screen compared to said second display unit such that said first display area is a small display area and said second display area is a large display area,

wherein said first client system determines that said first sub-menu and said second sub-menu are to be displayed in said overlapping style in view of said first display area having said small display area,

wherein said second client system determines that said first sub-menu and said second sub-menu are to be displayed in said cascading style in view of said second display area having said large display area.

10. The computing system of claim 1, wherein said context menu is rendered in said first client system by a first application in a small display area such that said first display area is said small display area,

wherein said context menu is rendered in said second client system by a second application in a large display area such that said second display area is said large display area.

11. A non-transitory computer readable medium storing one or more sequences of instructions, wherein execution of said one or more sequences of instructions by one or more processors contained in a server system causes said server system to support context menus in client systems, wherein execution of said one or more instructions by one or more processors contained in said server system causes said server system to perform the actions of:

sending a context menu associated with a first graphical element to both a first client system and a second client system, said context menu containing a first sub-menu and a second sub-menu, wherein said second sub-menu is represented as a child of a parent menu item contained in said first sub-menu,

wherein said first client system displays said first sub-menu and said second sub-menu in an overlapping style on a first display unit associated with said first client system, and

said second client system displays said first sub-menu and said second sub-menu in a cascaded style on a second display unit associated with said second client system,

wherein said context menu is displayed in a first display area on said first display unit and in a second display area on said second display unit, wherein said first display area is smaller than said second display area,

wherein said second sub-menu is displayed upon selection of said parent menu item in each of said first client system and said second client system,

wherein said first sub-menu and said second sub-menu are displayed in said cascading style in said first client system in view of said first display area being smaller than said second display area.

12. The non-transitory computer readable medium of claim 11, wherein each of said first client system and said second client system displays a corresponding web page containing said first graphical element,

each of said first client system and said second client system displaying said first sub-menu upon a first user action with respect to said first graphical element displayed on the corresponding web page,

wherein said selection is performed based on said displaying of said first sub-menu.

13. The non-transitory computer readable medium of claim 11, wherein said first display unit has a smaller display screen compared to said second display unit such that said first display area is a small display area and said second display area is a large display area,

wherein said first client system determines that said first sub-menu and said second sub-menu are to be displayed in said overlapping style in view of said first display area having said small display area,

wherein said second client system determines that said first sub-menu and said second sub-menu are to be displayed in said cascading style in view of said second display area having said large display area.

14. The non-transitory computer readable medium of claim 11, wherein said context menu is rendered in said first client system by a first application in a small display area such that said first display area is said small display area,

wherein said context menu is rendered in said second client system by a second application in a large display area such that said second display area is said large display area.
