Abstract

A method for rendering a portal graphical user interface (GUI), comprising providing for the representation of a GUI desktop, a GUI look and feel, and a GUI book as a set of controls wherein the controls can be organized in a logical hierarchy, traversing the representation, wherein the traversing comprises associating a theme with a first control in the set of controls, rendering the first control according to the theme, rendering any descendents of the first control according to the theme, wherein any descendents of the first control can override the theme, and wherein one of the set of controls can communicate with another of the set of controls.

Claims

1. A method for rendering a portal graphical user interface (GUI) for a portal, comprising:

providing a set of controls, wherein the set of controls can be organized in a logical hierarchy, wherein each said control represents a corresponding graphical element in the portal GUI, wherein each said control has properties that can be read and set, wherein each said control is implemented as one or more classes in an object-oriented programming paradigm, wherein each said control has one or more methods which can be overridden to provide specialization of each said control;

traversing, using at least one processor, the logical hierarchy, wherein the traversing comprises;

associating a first theme with a first control in the set of controls;

associating descendents of the first control according to the first theme unless the theme is overridden;

overriding a second control, which is a descendent of the first control, with a second theme such that the second control uses the second theme and any descendent of the second control uses the second theme unless the second theme is overridden;

using a first thread to render the first control according to the first theme, and a second thread to render the second control according to the second theme, wherein the rendering of the first control by the first thread is in parallel to the rendering of the second control by the second thread; and

after the first thread finishes rendering the first control according to the first theme and the second thread finishes rendering the second control according to the second theme, using a mainline render to obtain rendering result for the first control from the first thread and render result for the second control from the second thread.

2. The method of claim 1 further comprising:

representing a desktop in the GUI by a desktop control, wherein the desktop is a view of a portal, and wherein the desktop control is hierarchically superior to a shell control in the GUI and to a book control in the GUI.

3. The method of claim 1 further comprising:

using a look and feel control to determine an appearance of the portal.

4. The method of claim 1 further comprising:

using a book to navigate to at least one portal page in the portal, and wherein the book is represented by a book control.

5. The method of claim 1 further comprising:

using one control of the set of controls to respond to an event raised by another control of the set of controls.

6. The method of claim 1 further comprising:

associating an interchangeable persistence mechanism with a control of the set of controls.

7. The method of claim 1 further comprising:

associating an interchangeable rendering mechanism with a control of the set of controls.

8. The method of claim 1, further comprising:

accepting a request to access the portal.

9. The method of claim 8 further comprising:

allowing the request to be a hypertext transfer protocol (HTTP) request.

10. The method of claim 8 further comprising:

originating the request from a Web browser.

11. The method of claim 1, further comprising:

generating a response from the portal.

12. The method of claim 1 further comprising:

using a control of the set of controls to represent one of;

button, text field, menu, table, window, window control, title bar, pop-up window, check-box button, radio button, window frame, desktop, shell, head, body, header, footer, book, page, layout, placeholder, portlet and toggle button.

13. The method of claim 1 further comprising:

allowing the first control to inherit the first theme from a parent control.

14. The method of claim 1 further comprising:

using the first theme to specify at least one of the appearance and functioning of a control in the GUI.

15. The method of claim 1 further comprising:

specifying the first theme in whole or in part by a properties file.

16. The method of claim 15 further comprising:

including in the properties file at least one of;

     1) cascading style sheet;

     2) Java Server Page;

     3) Extensible Markup Language;

     4) text;

     5) Hypertext Markup Language;

     6) Extensible Hypertext Markup Language;

     7) JavaScript; and

     8) Flash MX.

17. The method of claim 15 further comprising:

using the properties file to specify at least one image.

18. The method of claim 1 further comprising:

using the GUI as a part of a portal on the World Wide Web.

38. The method of claim 1, further comprising:

including content from an external site in at least one thread that is used to render one or more controls of the set of controls.

39. The method of claim 1, further comprising:

allowing the first thread that renders the first control to interact with the second thread that renders the second control through an event notification mechanism.

40. The method of claim 1, further comprising:

using a factory to instantiate a worker for each thread in order to render at least one control of the set of set of controls and gathering context information for said each thread including association of said each thread with the main thread.

19. A machine readable storage medium having instructions stored thereon that when executed by a processor cause a system to:

provide a set of controls, wherein the set of controls are organized in a logical hierarchy, wherein each said control represents a corresponding graphical element in a portal graphical user interface (GUI) for a portal, wherein each said control has properties that can be read and set, wherein each said control is implemented as one or more classes in an object-oriented programming paradigm, wherein each said control has one or more methods which can be overridden to provide specialization of each said control;

traverse the logical hierarchy, wherein the traversing comprises instructions to cause the system to;

associate a first theme with a first control in the set of controls;

associate descendents of the first control according to the first theme unless the theme is overridden;

override a second control, which is a descendent of the first control, with a second theme such that the second control uses the second theme and any descendent of the second control uses the second theme unless the second theme is overridden;

use a first thread to render the first control according to the first theme, and a second thread to render the second control according to the second theme, wherein the rendering of the first control by the first thread is in parallel to the rendering of the second control by the second thread; and

after the first thread finishes rendering the first control according to the first theme and the second thread finishes rendering the second control according to the second theme, use a mainline render to obtain rendering result for the first control from the first thread and render result for the second control from the second thread.
