Application sharing event control device and control method using the same

The present invention is to perform a collaboration when a collaborative distributed control system that supports a collaborative performance by sharing the application and information used as a tool of development by a plurality of developers in a distributed environment The present invention relates to a procedure for requesting a sharing event of an application required for an application and an application sharing event controller capable of processing a response message in another engine after the request, and a control method using the same.

In general, processing of application sharing events for collaboration consists of centralized application sharing event processing and application sharing event processing in a replication structure.

Using the conventional method for collaboration, which consists of the method of handling the application sharing event for collaboration, the application sharing event processing under the centralized structure has all applications to be shared on a single server, and collaboration In order to process application sharing events by receiving application sharing events of all sites from the server and processing application sharing events to execute the application of the server performed for the purpose. As many application-sharing event handlers as there are applications have to be created, the performance of the server is drastically degraded when many applications are running. In addition, in order to handle application sharing events under the replication structure, all the systems of all sites must have the same application, and the applications of all the sites driven for collaboration are executed. Therefore, the processing of application sharing events is very complicated. And synchronization is very difficult.

Accordingly, the present invention provides keystroke and mouse input information, which is information input as an application sharing event, in a distributed structure capable of supporting an environment in which developers can share an application for collaborative development of information and communication system software. The purpose of the present invention is to provide an application sharing event control device and a control method using the same, for processing an event for application execution at a site having an application for processing and for processing keyboard and mouse information generated for accessing a shared application from a client. do.

In addition, as an additional feature of the present invention, all users have an application sharing event handler, so when a user wants to collaborate by sharing another application that is not currently being shared, the application of the site that is not currently being used is selected. It's easy to do another form of collaboration. At this time, the site where the application is run is designated as a server, the application sharing event handler is driven to share the application to facilitate the application sharing event control device and control method using the same do.

Application sharing event control apparatus for realizing the above object is a message dispatcher for bringing the messages delivered from the server and the client in the order of storage, and the user event and system events by interpreting the message patched through the message dispatcher; An interpreter that classifies an application sharing event, an application sharing event handler that processes the message interpreted by the interpreter, and a message processed by the application sharing event handler when all the presentations of the object are finished to all nodes through COVA. Consists of a distributor to deliver.

An application sharing event control method for realizing the above object includes executing a window manager for driving a collaboration system, and checking a driving state of the shared application when driving the shared application in the UIMS of the collaboration system. And a step for processing an application sharing event by performing an application sharing event, and comparing the shared application checked from the step to an active state, from which the shared application is activated and the application Driving the shared event handler of, and unloading the shared event handler of the application when the shared application is terminated, and driving the shared event action of the application from the step, Unloading the sharing event action of the application when the application is finished using the application; performing an application sharing event to process the application sharing event; receiving an application sharing event via a network; receiving from the step Dispatching the shared application sharing event, interpreting the application sharing event dispatched from the step, determining whether the message interpreted from the step is an application sharing event, and the determined message is not an application sharing event. Returning to the step of interpreting, if the interpreted message is an application sharing event, the step of proceeding to the next step, and classifying the message delivered from the step into information that can be performed in the application And transferring the information converted from the step to the next step, performing the information received from the step, processing the shared application result performed from the step, Distributing the results of the shared application processed from the step to the collaborative participants through the network.

The present invention is driven by a first process of running an application to share a GUI (Graphic User Interface) that can be used in a windowing environment, processing a shared event of the shared application, and an application sharing event delivered in the first step. It includes performing a second process of performing the application and a third process of delivering the application execution results generated during the execution of the second process to the users participating in the collaboration.

Hereinafter, an application sharing event control apparatus and a control method using the same according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an information communication system software co-development platform to which the present invention is applied.

In particular, FIG. 1 is a functional block diagram of a collaboration system for developing information and communication system software. The distributed control engine of the structure operates mainly in a distributed environment, and the environment of a user system for collaboration in a distributed environment is User interface management system (UIMS) 11 for effective use of collaboration, communication system 12 for exchanging multi-party information in a distributed environment, and sharing as a workspace to support collaboration It consists of a work environment 13, an event engine 14 that supports application sharing when collaborating and handles events of a shared application, and CORBA 20 for supporting a distributed computing environment between user systems. The tools needed for collaboration under these circumstances (15, 16, 17, 31, 32, 33, 41, 42, 43) It is distributed to users and provides an environment where people can share tools and collaborate for the purpose of co-development. The operation of this system is to set up a collaboration environment by selecting a tool and user suitable for the purpose of collaboration in UIMS (11). At this time, if a shared application exists in the system, the event engine (14) is driven and the server Create a mode and run the application in the shared work environment 13. In addition, by requesting the collaborators to collaborate, distributing application sharing information to the users who approved the request, setting up the collaboration environment, and user events during the collaboration process, the event engine 14 Event information is shared and processed.

2 is a block diagram showing a collaborative distributed control engine to which the present invention is applied, in which a node owning an application 5 to collaborate serves as a server. There is an interpreter (2) that analyzes the messages delivered from the server and clients in the order in which they are stored in the message dispatcher (1), and then classifies them into user events, system events, and application sharing events. When the delivered message is delivered to the application sharing event handler 3, in the application sharing event handler 3, the window manager is a part defining the structure of IDs of the running windows of the node according to the message type. In the forwarded message on the server side, the mapping information of the window ID currently being executed by the server and the window ID to be executed by the client is converted to the window handle to be presented to the node. You use this window handle to create a Windows command using the information in the message mapping table to create a Windows command to pass to the application sharing event action module and Windows. When generating a Windows command, information about the object to be presented is stored in the window message mapping table, which is used as information for controlling the synchronization of the objects. At the end of the presentation, that is, all the sharing of the objects has been completed, the message mapping table is also stored so that users of other nodes can use the objects. If the presentation of the object is input while presenting the object, the lock processing module is activated to delay the presentation, thereby ensuring the integrity of the object. When the presentation of the object is finished, the distributor 4 delivers the message to all nodes by COVA, which is a distributed object reference model, and the received nodes go through the above process. In other words, the presentation of the object at the client is made through the client engine's message dispatcher 6, interpreter 7 and application sharing event handlers 8. When the presentation ends, a termination message is sent to the server to be used as information for the lock process.

FIG. 3 is a flowchart of an application sharing event processor. The flowchart is driven from a step of driving an application S12 for sharing through a window manager S11 and then selecting and driving an application to be shared. When the shared application is driven in the UIMS of the collaboration system, the driving state of the shared application is checked (S10), and when the driving is completed, the application is activated after comparing the active state of the shared application (S5), and the shared event of the application. The processor is driven (S6), and the next step is to drive the functional block (S8) capable of performing the application sharing event, to prepare for processing the application sharing event. In this case, when an application sharing event is received through the network (S1), an application sharing message is received through the dispatcher (S2) and an interpreter (S3), and if the received message is an application sharing event (S4), an application sharing event handler This message is delivered to S8, and the application sharing event processor S8 classifies the received message, converts the received message into information that can be performed in the application, and delivers the message to the application sharing event executor S9. The application sharing event performer (S9) receiving the event delivers the event so that the received information can be performed in the sharing application (S12). The result of the application execution is transmitted from the shared application result processor S13 to the shared application result distributor S14, which distributes the result to the collaborators through the network. Application sharing events for the holders of the shared application are delivered directly to the application sharing event handler S8 for processing. If the shared application is finished using, the shared application state check S10 detects information and unloads the shared event processor S6 and the shared event action S7.

As described above, according to the present invention, an application sharing event control method is applied to a fully distributed structure in an environment of a structured distributed cooperative control structure, thereby providing an environment that can more efficiently handle collaboration.
