Abstract

Techniques for optimizing window move actions for a remoted application are provided, where the remoted application has an application window running within a remote desktop of a server system, and where the application window is made accessible to a user of a client system in the form of a client-side application window displayed in a client desktop of the client system. In one embodiment, the client system can receive from the server system a notification that the application window has begun moving in the remote desktop, and can determine that the user is currently entering one or more input commands for moving the client-side application window in the client desktop. The client system can further send a command to the server system for stopping the movement of the application window in the remote desktop, such that the application window is fixed in a stationary position. The client system can then allow the user to continue moving the client-side application window in the client desktop, while the application window remains in the stationary position in the remote desktop.

Claims

1. A method for optimizing window move actions for a remoted application, wherein the remoted application has an application window running within a remote desktop of a server system, and wherein the application window is made accessible to a user of a client system in the form of a client-side application window displayed in a client desktop of the client system, the method comprising:

determining, by the client system, that the user has begun moving the client-side application window in the client desktop;

sending, by the client system to the server system, a command for fixing the application window in a stationary position in the remote desktop; and

while the user continues moving the client-side application window in the client desktop;

determining, by the client system, a fixed area in the remote desktop that corresponds to the stationary position of the application window in the remote desktop;

receiving, by the client system, a remote desktop framebuffer from the server system; and

copying, by the client system, a portion of the remote desktop framebuffer covered by the fixed area to the client-side application window in the client desktop.

2. The method of claim 1 wherein the client system repeats the steps of receiving the remote desktop framebuffer and copying the portion of the remote desktop framebuffer covered by the fixed area on a periodic basis until the user finishes moving the client-side application window in the client desktop.

3. The method of claim 1 further comprising:

determining that the user has finished moving the client-side application window;

determining a final position of the client-side application window in the client desktop; and

sending a request to the server system for moving the application window in the remote desktop to the final position.

4. The method of claim 1 wherein copying the portion of remote desktop framebuffer covered by the fixed area to the client-side application window in the client window comprises:

blitting the portion into the client-side application window, the blitting causing the client-side application window to display the most current content of the application window in the remote desktop.

5. The method of claim 1 wherein the application window remains fixed in the stationary position in the remote desktop until the user finishes moving the client-side application window.

6. The method of claim 1 wherein determining that the user has begun moving the client-side application window in the client desktop comprises:

receiving, from the server system, a notification that the application window has begun moving in the remote desktop.

7. The method of claim 6 wherein the command for fixing the application window in the stationary position is a command instructing the server system to stop or cancel movement of the application window in the remote desktop.

8. A non-transitory computer readable medium having stored thereon software executable by a client system, the software embodying a method for optimizing window move actions for a remoted application, wherein the remoted application has an application window running within a remote desktop of a server system, and wherein the application window is made accessible to a user of the client system in the form of a client-side application window displayed in a client desktop of the client system, the method comprising:

determining that the user has begun moving the client-side application window in the client desktop;

sending, to the server system, a command for fixing the application window in a stationary position in the remote desktop; and

while the user continues moving the client-side application window in the client desktop;

determining a fixed area in the remote desktop that corresponds to the stationary position of the application window in the remote desktop;

receiving a remote desktop framebuffer from the server system; and

copying a portion of the remote desktop framebuffer covered by the fixed area to the client-side application window in the client desktop.

9. The non-transitory computer readable medium of claim 8 wherein the client system repeats the steps of receiving the remote desktop framebuffer and copying the portion of the remote desktop framebuffer covered by the fixed area on a periodic basis until the user finishes moving the client-side application window in the client desktop.

10. The non-transitory computer readable medium of claim 8 wherein the method further comprises:

determining that the user has finished moving the client-side application window;

determining a final position of the client-side application window in the client desktop; and

sending a request to the server system for moving the application window in the remote desktop to the final position.

11. The non-transitory computer readable medium of claim 8 wherein copying the portion of remote desktop framebuffer covered by the fixed area to the client-side application window in the client window comprises:

blitting the portion into the client-side application window, the blitting causing the client-side application window to display the most current content of the application window in the remote desktop.

12. The non-transitory computer readable medium of claim 8 wherein the application window remains fixed in the stationary position in the remote desktop until the user finishes moving the client-side application window.

13. The non-transitory computer readable medium of claim 8 wherein determining that the user has begun moving the client-side application window in the client desktop comprises:

receiving, from the server system, a notification that the application window has begun moving in the remote desktop.

14. The non-transitory computer readable medium of claim 13 wherein the command for fixing the application window in the stationary position is a command instructing the server system to stop or cancel movement of the application window in the remote desktop.

15. A client system comprising:

a processor; and

a non-transitory computer readable medium having stored thereon program code for optimizing window move actions for a remoted application, wherein the remoted application has an application window running within a remote desktop of a server system, and wherein the application window is made accessible to a user of the client system in the form of a client-side application window displayed in a client desktop of the client system,

the program code causing the processor to;

determine that the user has begun moving the client-side application window in the client desktop;

send, to the server system, a command for fixing the application window in a stationary position in the remote desktop; and

while the user continues moving the client-side application window in the client desktop;

determine a fixed area in the remote desktop that corresponds to the stationary position of the application window in the remote desktop;

receive a remote desktop framebuffer from the server system; and

copy a portion of the remote desktop framebuffer covered by the fixed area to the client-side application window in the client desktop.

16. The client system of claim 15 wherein the program code further causes the processor to repeat the steps of receiving the remote desktop framebuffer and copying the portion of the remote desktop framebuffer covered by the fixed area on a periodic basis until the user finishes moving the client-side application window in the client desktop.

17. The client system of claim 15 wherein the program code further causes the processor to:

determine that the user has finished moving the client-side application window;

determine a final position of the client-side application window in the client desktop; and

send a request to the server system for moving the application window in the remote desktop to the final position.

18. The client system of claim 15 wherein copying the portion of remote desktop framebuffer covered by the fixed area to the client-side application window in the client window comprises:
