Abstract

A display apparatus and method that provides a windowing interface that gives the user the capability to toss a window on a display screen by selecting a window by engaging the pointing device, moving the window by moving the pointing device and tossing the window by disengaging the pointing device, whereby the window continues to move after the user has disengaged the pointing device. A portion of the window is optionally kept on the screen so that the window is not tossed completely off of the screen.

Claims

1. A display apparatus for moving a window on a screen, using a pointing device containing button means, comprising:

displaying means for displaying a window on the screen;

moving means for moving said window in response to a user using said pointing device while engaging said button means; and

tossing means for continuing to move said window after said user has disengaged said button means.

2. The display apparatus of claim 1, wherein said tossing means further comprises friction means for slowing movement rate of said window until said window has stopped moving.

3. The display apparatus of claim 2, wherein said tossing means further comprises stopping means for stopping movement of said window when said window reaches a predetermined percent remaining on said screen.

4. The display apparatus of claim 3, wherein said predetermined percent is determined by the user.

5. The display apparatus of claim 1, wherein said moving means further comprises means for generating a stream of move events corresponding to positions of said window as said window is moved by the user via said pointing device.

6. The display apparatus of claim 2 wherein said screen has a horizontal and a vertical axis and said friction means further comprises both a horizontal and vertical component corresponding to said horizontal and said vertical axis.

7. A method for moving a window on a screen using a pointing device, comprising the computer executed steps of:

displaying a window on the screen;

moving said window in response to a user using said pointing device while engaging said pointing device; and

tossing said window after said user has disengaged said pointing device.

8. The method of claim 7, wherein said tossing step further comprises a friction component for slowing movement rate of said window until said window has stopped moving.

9. The method of claim 8, wherein said tossing step further comprises stopping movement of said window when said window reaches a predetermined percent remaining on said screen.

10. The method of claim 9, wherein said predetermined percent is determined by the user.

11. The method of claim 7, wherein said moving step further comprises generating a stream of move events corresponding to positions of said window as said window is moved by the user via said pointing device.

12. The method of claim 8 wherein said screen has a horizontal and a vertical axis and said friction component further comprises both a horizontal and vertical component corresponding to said horizontal and said vertical axis.

13. A computer system, comprising:

a processor;

a display device having a screen, coupled to said processor;

a pointing device containing button means, coupled to said processor;

displaying means for displaying a window on the screen;

moving means for moving said window in response to a user using said pointing device while engaging said button means; and

tossing means for continuing to move said window after said user has disengaged said button means.

14. The computer system of claim 13, wherein said tossing means further comprises friction means for slowing movement rate of said window until said window has stopped moving.

15. The computer system of claim 14, wherein said tossing means further comprises stopping means for stopping movement of said window when said window reaches a predetermined percent remaining on said screen.

16. The computer system of claim 15, wherein said predetermined percent is determined by the user.

17. The computer system of claim 13, wherein said moving means further comprises means for generating a stream of move events corresponding to positions of said window as said window is moved by the user via said pointing device.

18. The computer system of claim 14 wherein said screen has a horizontal and a vertical axis and said friction means further comprises both a horizontal and vertical component corresponding to said horizontal and said vertical axis.
