Abstract

A method and system for generating variable modality child windows. An application is executed utilizing a graphical user interface (GUI) which enables a parent window. One or more child windows may be available to the user during execution. The level of modality of the child window is determined during programming by the application developer. The operating system is modified to permit a variable level of modality during application execution. The developer selects variable modality for one or more of the child windows. When the child window is opened, the user is allowed to interact with the other windows based on the developers determination of level of modality. The variability may be either application or system-wide. The user is thus permitted to interface with only some of the functions on the other windows on the desktop while the child window is open.

Claims

1. A method of improving child window functionality of a computer application, said method comprising the steps of:

providing a plurality of modality levels including a variable level modality for a child window of said computer application;

designating a variable level modality of said child window to an operating system associated with said computer application, wherein said variable level modality distinguishes between a system and an application level and allows access to permitted features outside of said child window while said child window is opened;

in response to a selection of a feature outside of said child window while said child window is open, determining that said feature is a permitted feature external to said child window; and

in response to said determining step, accessing said feature.

2. The method of claim 1, wherein said designating step further provides granular, disparate specifications of user interaction outside of said child window.

3. The method of claim 2, wherein said accessing step includes minimizing, maximizing and restoring a parent window associated with said child window.

4. The method of claim 2, further comprising the step of submerging said child window below the parent window when said permitted feature is selected.

5. The method of claim 2, wherein said accessing step accesses a menu item selection from a parent window associated with said child window.

6. The method of claim 1, further comprising the steps of:

providing a graphical user interface with selection options for child window modality, including full modality, non-modality, and variable modality;

in response to a receipt of a user selection, associating a selected one of said selection options with said child window of said computer application.

7. The method of claim 6, further comprising the steps of toggling said variable level modality on in response to a user selection of said variable modality from among said selection options.

8. A data processing system for improving child window functionality of a computer application, said data processing system comprising:

a processor;

an operating system executed via said processor; and

program instructions executed by said processor that provides;

a modality selection function providing a plurality of modality levels for a child window of said computer application and which includes means for designating to the operating system a variable modality for said child window; and

a response utility that, in response to a selection of a feature outside of said child window while said child window is open, determines that said feature is a permitted one of a set of external features, that can be accessed while said child window is open and accesses said feature.

9. The data processing system of claim 8, wherein said modality selection function distinguishes between system and application levels of modality.

10. The data processing system of claim 9, wherein said modality selection function provides features by which a user may minimize, maximize, and restore a parent window of said child window.

11. The data processing system of claim 9, wherein said modality selection function provides that a child window may be submerged below the parent window for certain specified user interactions.

12. The data processing system of claim 9, wherein said modality selection function further permits a a user access to a menu selection of a parent window of said child window.

13. A computer program product comprising:

a storage medium adapted to be read by a computer; and

program instructions stored on said storage medium for enabling a variable level modality for a child window of a computer application, by (1) implementing a programming environment, which allows an application developer to select one of a plurality of modalities for a child window including said variable level modality which provides access to particular features outside of said child windows, and (2) designating the variable level modality for said child window.

14. The computer program product of claim 13, wherein said program instructions further includes instructions for designating to the operating system the variable level modality for said child windows.

15. The computer program product of claim 13, wherein said program instructions includes instructions for distinguishing between system and application levels of modality.

16. The computer program product of claim 15, wherein said program instructions includes instructions that allow a user to minimize, maximize, and restore a parent window of said child window while said child window is open.

17. The computer program product of claim 15, wherein program instructions includes instructions for submerging a child window below a parent window for certain specified user interactions.

18. The computer program product of claim 15, wherein program instructions includes instructions for allowing a user to access a selected menu of a parent window of said child window.
