Abstract

A system for incorporating windows from remote desktop environments into a local desktop environment includes a local node, a local agent, a first remote node, and a first remote agent. The first remote node provides a first remote desktop environment, and the first remote agent monitors the first remote desktop environment for changes in the environment. The first remote node transmits messages to the local agent indicative of changes in the first remote desktop environment. The local agent receives the transmitted messages and commands the local node to modify a representation of a first remote window that is part of a local desktop environment. The local agent also monitors the local desktop and transmits messages to the remote agent indicative of a change in the local desktop. In some embodiment, the local node provides the local desktop environment. Local agents can be embodied on articles of manufacture.

Claims

1. A system for incorporating at least one remote window from a remote desktop environment into a local desktop environment, the system comprising:

a first virtual channel coupled to the remote desktop environment and conveying graphical data associated with the remote window;

a second virtual channel coupled to the remote desktop environment and conveying window attribute data associated with the remote window; and

a local agent coupled to the remote desktop environment via the first and second virtual channels, the local agent directing the formation of a corresponding window in the local desktop environment, the corresponding window displaying the graphical data conveyed by the first virtual channel in accordance with the window attribute data conveyed by the second virtual channel.

2. The system of claim 1 further comprising a combined windows list being formed and maintained by the local agent, the combined windows list representing a modifiable z-order of the corresponding window in the local desktop environment.

3. The system of claim 1 wherein the window attribute data associated with the remote window and conveyed by the second virtual channel includes the size and z-order of the remote window.

4. The system of claim 1 further comprising a local operating system forming the local desktop environment, the local agent periodically polling the local operating system to detect an attribute change in the corresponding window, wherein the local agent transmits a message to the remote desktop environment indicative of the attribute change.

5. The system of claim 1 wherein the corresponding window exhibits window attribute data substantially similar relative to the local desktop environment as the window attribute data of the remote window relative to the remote desktop environment.

6. The system of claim 1 further comprising a plurality of communication links coupling the local desktop environment with a plurality of remote desktop environments, the communication links including first and second virtual channels conveying graphical and window attribute data associated with remote windows from the plurality of remote desktop environments to the local agent, wherein the local agent forms corresponding windows in the local desktop environment corresponding to each of the plurality of remote windows.

7. A method of incorporating at least one remote window from a remote desktop environment into a local desktop environment, the method comprising the steps of:

receiving graphical data associated with the remoted window via a first virtual channel coupled to the remote desktop environment;

receiving window attribute data associated with the remote window via a second virtual channel coupled to the remote desktop environment; and

forming a corresponding window in the local desktop environment, the corresponding window displaying the graphical data received from the first virtual channel in accordance with the window attribute data received from the second virtual channel.

8. The method of claim 7 further comprising the step of forming a combined windows list storing at least some of the window attribute data.

9. The method of claim 7 further comprising the steps of:

polling a local operating system associated with the local desktop environment to detect an attribute change in the corresponding window; and

transmitting a message to the remote desktop environment indicative of the detected attribute change.

10. The method of claim 7 wherein the corresponding window exhibits window attribute data substantially similar relative to the local desktop environment as the window attribute data of the remote window relative to the remote desktop environment.

11. A system for incorporating at least one remote window from a remote desktop environment into a local desktop environment, the system comprising:

a first virtual channel coupled to the local desktop environment and conveying graphical data associated with the remote window;

a second virtual channel coupled to the local desktop environment and conveying window attribute data associated with the remote window; and

a remote agent associated with the remote desktop environment and coupled to the local desktop environment via the first and second virtual channels, the remote agent transmitting messages to the local desktop environment directing the formation of a corresponding window in the local desktop environment, the corresponding window displaying the graphical data conveyed by the first virtual channel in accordance with the window attribute data conveyed by the second virtual channel.

12. The system of claim 11 further comprising a combined windows list formed in response to the messages transmitted by the remote agent and including at least some of the window attribute information conveyed via the second virtual channel.

13. The system of claim 11 wherein the window attribute data associated with the remote window and conveyed by the second virtual channel includes the size and z-order of the remote window.

14. The system of claim 11 further comprising a remote operating system forming the remote desktop environment, the remote agent periodically polling the remote operating system to detect an attribute change in the remote window, wherein the remote agent transmits a message to the local desktop environment indicative of the attribute change.

15. The system of claim 11 wherein the corresponding window exhibits window attribute data substantially similar relative to the local desktop environment as the window attribute data of the remote window relative to the remote desktop environment.

16. The system of claim 11 further comprising a plurality of communication links coupling the remote desktop environment with a plurality of local desktop environments, the communication links including first and second virtual channels conveying graphical and window attribute data associated with the remote window from the remote desktop environment to the plurality of local desktop environments, wherein the local desktop environments form corresponding windows corresponding to the remote window.

17. A method of incorporating at least one remote window from a remote desktop environment into a local desktop environment, the method comprising the steps of:

transmitting graphical data associated with the remote window via a first virtual channel coupled to the local desktop environment;

transmitting window attribute data associated with the remote window via a second virtual channel coupled to the local desktop environment; and

transmitting messages to the local desktop environment directing the formation of a corresponding window in the local desktop environment, the corresponding window displaying the graphical data transmitted via the first virtual channel in accordance with the window attribute data transmitted via the second virtual channel.

18. The method of claim 17 further comprising the step of forming a combined windows list storing at least some of the window attribute data in response to the transmitted messages.

19. The method of claim 17 further comprising the steps of:

polling a remote operating system associated with the remote desktop environment to detect an attribute change in the remote window; and

transmitting a message to the local desktop environment indicative of the detected attribute change.
