Abstract

Embodiments of the present invention provide methods and system for “borrowing” and giving back a window from one computer to another. Borrowing refers to actions performed by one computer to temporarily obtain and control a window from another computer.

Claims

1. A method of borrowing a window from a host computer, said method comprising:

determining which windows at the host computer are eligible to be borrowed by a second computer over a network connection;

selecting at least one of the determined eligible windows, wherein the selected window is a graphical user interface for an application running on the host computer;

removing the selected window from the host computer; and

directing display data for the selected window on the host computer to the second computer.

2. The method of claim 1, wherein determining which windows at the host computer are eligible to be borrowed comprises:

determining which windows are currently displayed on the host computer; and

displaying a list of the windows that are currently displayed.

3. The method of claim 1, further comprising:

polling a local operating system for changes to the selected window.

4. The method of claim 1, further comprising inserting a button into a display of the host computer that triggers a return of the selected window to the host computer.

5. An apparatus comprising a memory containing instructions and a processor coupled to the memory and configured to execute the instructions to perform the method of claim 1.

6. A non-transitory computer readable medium containing program code having instructions that cause a processor to perform the method of claim 1.

7. The method of claim 1, further comprising:

displaying the directed display data in a window on the second computer.

8. A method of allowing a window at a host computer to be borrowed by a remote computer over a network connection, said method comprising:

receiving via the network connection a request to borrow a window from the remote computer;

providing information that indicates which windows at the host computer are eligible for borrowing;

receiving information that indicates which window has been selected for borrowing;

removing the selected window from the host computer, wherein the selected window is a graphical user interface for an application running on the host computer;

intercepting display data being generated by the host computer for the selected window; and

sending the display data for the selected window to the remote computer.

9. The method of claim 8, wherein providing information that indicates which windows are eligible for borrowing comprises transmitting a window to the remote computer that includes thumbnails of the windows that are eligible for borrowing.

10. The method of claim 8, wherein intercepting display data for the selected window comprises:

identifying display data that corresponds to the selected window; and

routing only the display data that corresponds to the selected window.

11. An apparatus comprising a memory containing instructions and a processor coupled to the memory and configured to execute the instructions to perform the method of claim 8.

12. A non-transitory computer readable medium containing program code having instructions that causes a processor to perform the method of claim 8.

13. A system configured to allow a user operating from a first processor to borrow a window for an application running on a second processor, wherein the user is authorized on the second processor, said system comprising:

the first processor configured to determine which windows at the second processor are eligible to be borrowed, to select an eligible window, and to borrow the selected window by obtaining exclusive control of the selected window, wherein the selected window is a graphical user interface for an application running on the second processor; and

the second processor, coupled to the first processor, and configured to receive a request to borrow a window, to provide information that indicates which windows are eligible for borrowing, to determine which eligible window has been selected for borrowing, to remove the selected window, to intercept display data being generated by the second processor for the selected window, to redirect the display data for the selected window to the first processor.

14. The system of claim 13, wherein the first processor is configured to recognize changes to the borrowed window and transmit the changes back to the second processor.

15. The system of claim 13, wherein the first processor is configured to confirm that the user is logged in to the second processor.

16. The system of claim 13, wherein the second processor is configured to display information that indicates the selected window has been selected for borrowing when the display data is being redirected.

17. The system of claim 13, wherein the second processor is configured to take back the window selected for borrowing in response to a user input.

18. The system of claim 13, wherein the second processor is configured to take back the window selected for borrowing when the connection between the first and second processors has failed.
