// 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.
