Abstract

Methods and apparatus, including computer systems and program products, for providing and using design time support for application elements. A system for designing applications includes an extension point operable to receive a definition of a user interface element to be included in an application; one or more additional extension points, each additional extension point operable to receive one or more additional support items for the user interface element independently of receiving the definition of the user interface element; a display area operable to display the user interface element in an application screen based on the definition of the user interface element and the one or more additional support items; and, a mechanism operable to invoke one or more of the additional support items. Support items may include rendering information for the user interface element, and tools operable to modify the user interface element.

Claims

1. A computer program product, tangibly embodied in an information carrier, the computer program product comprising instructions operable to cause data processing apparatus to:

receive a definition for a user interface element;

independently of receiving the definition for the user interface element, receive rendering information for the user interface element;

independently of receiving the definition for the user interface element, receive a specification of a mechanism for modifying the user interface element; and

integrate the user interface element into an application as soon as the definition of the user interface element is received.

2. The product of claim 1, wherein the definition for the user interface element comprises:

a specification of one or more properties of the user interface element; and

a specification of a data type for each of the one or more properties of the user interface element.

3. The product of claim 2, wherein integrating the user interface element comprises:

displaying the one or more properties of the user interface element; and

enabling a user to modify the one or more properties of the user interface element.

4. The product of claim 1, wherein the rendering information comprises one or more graphic files.

5. The product of claim 1, wherein the rendering information comprises rendering code.

6. The product of claim 1, wherein integrating the user interface element comprises:

if the rendering information has not been received, rendering the user interface element in a preview area using default rendering information; and

if the rendering information has been received, rendering the user interface element in the preview area using the rendering information.

7. The product of claim 1, wherein the mechanism for modifying the user interface element comprises a wizard.

8. The product of claim 1, wherein the mechanism for modifying the user interface element is operable to generate one or more objects associated with the user interface element.

9. The product of claim 1, wherein the mechanism for modifying the user interface element is operable to generate a binding between the user interface element and an application element.

10. The product of claim 1, wherein integrating the user interface element comprises:

if the mechanism for modifying the user interface element has been received, enabling a user to invoke the mechanism for modifying the user interface element.

11. The product of claim 10, wherein enabling the user to invoke the mechanism comprises registering the mechanism in a development framework.

12. The product of claim 10, wherein enabling the user to invoke the mechanism comprises modifying a context item associated with the user interface element.

13. A method of developing applications, the method comprising:

specifying for a user interface element one or more properties and a data type for each of the one or more properties;

independently of specifying the one or more properties and the data type for each of the one or more properties, specifying rendering information to be used in place of default rendering information; and

integrating the user interface element into an application, wherein integrating the user interface element includes;

rendering the user interface element in a preview area using the default rendering information, if no rendering information has been specified; and

rendering the user interface element in a preview area using the specified rendering information, if rendering information has been specified.

14. The method of claim 13, wherein the method further comprises:

specifying a mechanism for modifying the user interface element; and

invoking the mechanism to modify the user interface element.

15. A system for designing applications comprising:

a first extension point operable to receive a definition of a first user interface element to be included in an application;

one or more additional extension points, each additional extension point operable to receive one or more additional support items for the first user interface element independently of receiving the definition of the first user interface element;

a display area operable to display the first user interface element in an application screen based on the definition of the first user interface element and the one or more additional support items; and

a mechanism operable to invoke one or more of the additional support items.

16. The system of claim 15, wherein the additional support items comprise rendering information for the first user interface element.

17. The system of claim 15, wherein the additional support items comprise a tool operable to modify the first user interface element.

18. The system of claim 15, wherein the first extension point is further operable to receive a definition of a second user interface element to be included in the application, the second user interface element being of a different type than the first user interface element.

19. The system of claim 15, wherein the additional support items are independent of the definition of the first user interface element.

20. The system of claim 15, wherein the additional support items are independent of each other.
