Send status information to UDP server To facilitate interaction with other applications WSJT-X now sends status updates to a predefined UDP server or multicast group address. The status updates include the information currently posted to the decodes.txt and wsjtx_status.txt files. An optional back communications channel is also implemented allowing the UDP server application to control some basic actions in WSJT-X. A reference implementaion of a typical UDP server written in C++ using Qt is provided to demonstrate these facilities. This application is not intended as a user tool but only as an example of how a third party application may interact with WSJT-X. The UDP messages Use QDataStream based serialization. Messages are documented in NetworkMessage.hpp along with some helper classes that simplify the building and decoding of messages. Two message handling classes are introduced, MessageClient and MessageServer. WSJT-X uses the MessageClient class to manage outgoing and incoming UDP messages that allow communication with other applications. The MessageServer class implements the kind of code that a potential cooperating application might use. Although these classes use Qt serialization facilities, the message formats are easily read and written by applications that do not use the Qt framework. MessageAggregator is a demonstration application that uses MessageServer and presents a GUI that displays messages from one or more WSJT-X instances and allows sending back a CQ or QRZ reply invocation by double clicking a decode. This application is not intended as a user facing tool but rather as a demonstration of the WSJT-X UDP messaging facility. It also demonstrates being a multicast UDP server by allowing multiple instances to run concurrently. This is enabled by using an appropriate multicast group address as the server address. Cooperating applications need not implement multicast techniques but it is recomended otherwise only a single appliaction can act as a broadcast message (from WSJT-X) recipient. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@5225 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

//
// MessageAggregator - an example application that utilizes the WSJT-X
// messaging facility
//
// This application is only provided as a simple GUI application
// example to demonstrate the WSJT-X messaging facility. It allows the
// user to set the server details either as a unicast UDP server or,
// if a multicast group address is provided, as a multicast server.
// The benefit of the multicast server is that multiple servers can be
// active at once each receiving all WSJT-X broadcast messages and
// each able to respond to individual WSJT_X clients. To utilize the
// multicast group features each WSJT-X client must set the same
// multicast group address as the UDP server address for example
// 239.255.0.0 for a site local multicast group.
//
// The UI is a small panel to input the service port number and
// optionally the multicast group address. Below that a table
// representing the log entries where any QSO logged messages
// broadcast from WSJT-X clients are displayed. The bottom of the
// application main window is a dock area where a dock window will
// appear for each WSJT-X client, this window contains a table of the
// current decode messages broadcast from that WSJT-X client and a
// status line showing the status update messages broadcast from the
// WSJT_X client. The dock windows may be arranged in a tab bar, side
// by side, below each other or, completely detached from the dock
// area as floating windows. Double clicking the dock window title bar
// or dragging and dropping with the mouse allows these different
// arrangements.
//
// The application also provides a simple menu bar including a view
// menu that allows each dock window to be hidden or revealed.

Send status information to UDP server To facilitate interaction with other applications WSJT-X now sends status updates to a predefined UDP server or multicast group address. The status updates include the information currently posted to the decodes.txt and wsjtx_status.txt files. An optional back communications channel is also implemented allowing the UDP server application to control some basic actions in WSJT-X. A reference implementaion of a typical UDP server written in C++ using Qt is provided to demonstrate these facilities. This application is not intended as a user tool but only as an example of how a third party application may interact with WSJT-X. The UDP messages Use QDataStream based serialization. Messages are documented in NetworkMessage.hpp along with some helper classes that simplify the building and decoding of messages. Two message handling classes are introduced, MessageClient and MessageServer. WSJT-X uses the MessageClient class to manage outgoing and incoming UDP messages that allow communication with other applications. The MessageServer class implements the kind of code that a potential cooperating application might use. Although these classes use Qt serialization facilities, the message formats are easily read and written by applications that do not use the Qt framework. MessageAggregator is a demonstration application that uses MessageServer and presents a GUI that displays messages from one or more WSJT-X instances and allows sending back a CQ or QRZ reply invocation by double clicking a decode. This application is not intended as a user facing tool but rather as a demonstration of the WSJT-X UDP messaging facility. It also demonstrates being a multicast UDP server by allowing multiple instances to run concurrently. This is enabled by using an appropriate multicast group address as the server address. Cooperating applications need not implement multicast techniques but it is recomended otherwise only a single appliaction can act as a broadcast message (from WSJT-X) recipient. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@5225 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

Send status information to UDP server To facilitate interaction with other applications WSJT-X now sends status updates to a predefined UDP server or multicast group address. The status updates include the information currently posted to the decodes.txt and wsjtx_status.txt files. An optional back communications channel is also implemented allowing the UDP server application to control some basic actions in WSJT-X. A reference implementaion of a typical UDP server written in C++ using Qt is provided to demonstrate these facilities. This application is not intended as a user tool but only as an example of how a third party application may interact with WSJT-X. The UDP messages Use QDataStream based serialization. Messages are documented in NetworkMessage.hpp along with some helper classes that simplify the building and decoding of messages. Two message handling classes are introduced, MessageClient and MessageServer. WSJT-X uses the MessageClient class to manage outgoing and incoming UDP messages that allow communication with other applications. The MessageServer class implements the kind of code that a potential cooperating application might use. Although these classes use Qt serialization facilities, the message formats are easily read and written by applications that do not use the Qt framework. MessageAggregator is a demonstration application that uses MessageServer and presents a GUI that displays messages from one or more WSJT-X instances and allows sending back a CQ or QRZ reply invocation by double clicking a decode. This application is not intended as a user facing tool but rather as a demonstration of the WSJT-X UDP messaging facility.
