Abstract

The present invention provides an interface, system, or method for displaying a window on a display in which a thumbnail corresponding to an application window is capable of being modified based on modifications in the application window. The modifications of the thumbnail may be accomplished in real-time. Also, the present invention provides an interface, system, and method for displaying a window or a thumbnail on a display in which a Desktop Window Manager (DWM) registers a source window and a destination window and/or may update or modify a thumbnail associated with the source window. Special effects may be applied to the thumbnail. The present invention further provides a method for registering and/or modifying a thumbnail and its properties or maintaining a list of thumbnail registrations.

Claims

1. A computer-implemented method of displaying a window containing a thumbnail on a display device, the method comprising:

displaying a taskbar with a taskbar button corresponding to the thumbnail where each taskbar button corresponds to an active application;

displaying a source window, the source window comprising first content that is capable of being modified;

displaying a destination window wherein at least a portion of the destination window includes the thumbnail, the thumbnail including second content corresponding to at least a portion of the first content of the source window;

registering the thumbnail to establish a relationship between the source window and the destination window through an application programming interface host to point back to and redraw the second content corresponding to at least a portion of the first content of the source window;

dynamically modifying the second content of the thumbnail through the application programming interface host between the first content of the source window and the second content of the thumbnail that determines whether the first content has changed since a previous comparison of the first content of the source window with the second content of the thumbnail and whenever the first content of the source window changes, the second content is modified by redrawing the second content based on how the first content of the source window changes; and

allowing a user-initiated view of the redrawn second content when a user positions a pointing device over a minimized instance of the destination window.

2. The method of claim 1 further comprising registering the thumbnail comprises receiving a window handle for said source window.

3. The method of claim 2 wherein the step of registering further comprises establishing an association between the source window and the thumbnail so that at least a portion of the first content of the source window is drawn into the thumbnail.

4. The method of claim 3 wherein the step of registering further comprises receiving a size parameter and storing the source window at a size corresponding to the size parameter.

5. The method of claim 4 wherein the registering further comprises receiving a unique handle representing the association between the source window and the thumbnail.

6. The method of claim 5 further comprising the step of unregistering the thumbnail, the unregistering comprising removing the unique handle representing the association between the source window and the thumbnail.

7. The method of claim 6 wherein the step of unregistering the thumbnail comprises deleting said unique handle representing the association between the source window and the thumbnail.

8. The method of claim 6 further comprising maintaining a list of window associations, the list of window associations comprising information of the association between the source window and the thumbnail.

9. The method of claim 1 further comprising receiving a first parameter for defining at least a portion of the source window, wherein said modifying comprises determining at least a portion of the source window to draw into the thumbnail based on said first parameter.

10. The method of claim 9 further comprising receiving a second parameter for defining at least a portion of the destination window, wherein said modifying further comprises determining at least a portion of the destination window to render the thumbnail based on said second parameter.

11. The method of claim 1 wherein said modifying further comprises receiving a control value and setting the opacity of the thumbnail based on the value of the control value.

12. The method of claim 11 wherein said modifying further comprises receiving a Boolean value and making the thumbnail invisible based on the Boolean value.

19. The computer-implemented method of claim 1, further comprising instructions for:

minimizing the source window; and

automatically displaying, in the thumbnail, a last content displayed by the source window prior to minimization.

20. The computer-implemented method of claim 1, wherein the thumbnail is modified in real-time as the content of the source window is modified.

21. The computer-implemented method of claim 1, wherein said step of automatically and continually modifying the second content of the thumbnail whenever the first content of the source window changes further includes the step of:

polling the source window at a predetermined interval to detect any change in the first content.

22. The computer-implemented method of claim 1, wherein modifying the thumbnail further comprises modifying the opacity of the thumbnail.

23. The computer-implemented method of claim 1, wherein modifying the thumbnail further comprises modifying the visibility of the thumbnail.

24. The computer-implemented method of claim 1, wherein modifying the thumbnail further comprises assigning visual priority to the thumbnail.

25. The method of claim 1 wherein the step of modifying the second content of the thumbnail occurs automatically whenever the first content window changes.

28. The method of claim 1 further comprising multiple source windows supporting the same destination window.

29. The method of claim 1 further comprising the ability to register at least a portion of an active window upon user-selected minimization for incorporation into a thumbnail mapping routine.

13. Computer-readable storage media having computer-executable instructions for performing steps directed to a thumbnail displayed within a display window on a device comprising:

displaying a taskbar with a taskbar button corresponding to the thumbnail where each taskbar button corresponds to an active application;

displaying a source window on a display, the source window comprising first content that is capable of being modified;

displaying a destination window wherein at least a portion of the destination window includes the thumbnail, the thumbnail including second content corresponding to at least a portion of the first content of the source window;

registering the thumbnail to establish a relationship between the source window and the destination window through an application programming interface host to point back to and redraw the second content corresponding to at least a portion of the first content of the source window;

dynamically modifying the second content of the thumbnail through the application programming interface host between the first content of the source window and the second content of the thumbnail that determines whether the first content has changed since a previous comparison of the first content of the source window with the second content of the thumbnail and whenever the first content of the source window changes, wherein the second content is modified by redrawing the second content based on how the first content of the source window changes; and

allowing a user-initiated view of the redrawn second content when a user positions a pointing device over a minimized instance of the destination window.

14. The computer-readable storage media of claim 13 having further computer-executable instructions for performing the step of:

maintaining a list of window associations comprising information of an association between the source window and the corresponding thumbnail.

15. The computer-readable storage media of claim 14 wherein said registering comprises:

receiving a window handle for the source window;

establishing an association between the source window and the corresponding thumbnail so that at least a portion of the first content of the source window is drawn into the thumbnail;

receiving a size parameter and storing the source window at a size corresponding to the size parameter;

receiving a unique handle representing the association between the source window and the destination window.

16. The computer-readable storage media of claim 14 wherein said modifying comprises:

determining at least a portion of the source window to draw into the destination window based on a first parameter for defining at least a portion of the source window;

determining at least a portion of the destination window to render the second content based on a second parameter for defining the thumbnail;

receiving a control value and setting the opacity of the thumbnail based on the value of the control value, wherein setting the opacity of the thumbnail is independent of a second opacity of the source window;

receiving a Boolean value and making the thumbnail invisible based on the Boolean value.

17. The computer-readable storage media of claim 14 further computer-executable instructions for performing the step of unregistering the thumbnail comprising deleting a unique handle representing the association between the source window and the thumbnail.

26. The computer-readable storage media of claim 13 wherein the step of modifying the second content of the thumbnail occurs automatically whenever the first content window changes.

18. A system for displaying a window containing a thumbnail on a display device, the system comprising:

a display for displaying a taskbar with a taskbar button corresponding to the thumbnail where each taskbar button corresponds to an active application;

a display for displaying a source window comprising content that is capable of being modified and a destination window corresponding to said source window;
