I.e., if the user tries to + launch another instance, the already running instance will be + activated instead. Another usecase is a client-server system, + where the first started instance will assume the role of server, + and the later instances will act as clients of that server. + + By default, the full path of the executable file is used to + determine whether two processes are instances of the same + application. You can also provide an explicit identifier string + that will be compared instead. + + The application should create the QtSingleApplication object early + in the startup phase, and call isRunning() to find out if another + instance of this application is already running. If isRunning() + returns false, it means that no other instance is running, and + this instance has assumed the role as the running instance. In + this case, the application should continue with the initialization + of the application user interface before entering the event loop + with exec(), as normal. + + The messageReceived() signal will be emitted when the running + application receives messages from another instance of the same + application. When a message is received it might be helpful to the + user to raise the application so that it becomes visible. To + facilitate this, QtSingleApplication provides the + setActivationWindow() function and the activateWindow() slot. + + If isRunning() returns true, another instance is already + running. It may be alerted to the fact that another instance has + started by using the sendMessage() function. Also data such as + startup parameters (e.g. the name of the file the user wanted this + new instance to open) can be passed to the running instance with + this function. Then, the application should terminate (or enter + client mode). + + If isRunning() returns true, but sendMessage() fails, that is an + indication that the running instance is frozen. + + Here's an example that shows how to convert an existing + application to use QtSingleApplication. It is very simple and does + not make use of all QtSingleApplication's functionality (see the + examples for that). + + \code + // Original + int main(int argc, char **argv) + { + QApplication app(argc, argv); + + MyMainWidget mmw; + mmw.show(); + return app.exec(); + } + + // Single instance + int main(int argc, char **argv) + { + QtSingleApplication app(argc, argv); + + if (app.isRunning()) + return !app.sendMessage(someDataString); + + MyMainWidget mmw; + app.setActivationWindow(&mmw); + mmw.show(); + return app.exec(); + } + \endcode + + Once this QtSingleApplication instance is destroyed (normally when + the process exits or crashes), when the user next attempts to run the + application this instance will not, of course, be encountered. The + next instance to call isRunning() or sendMessage() will assume the + role as the new running instance. + + For console (non-GUI) applications, QtSingleCoreApplication may be + used instead of this class, to avoid the dependency on the QtGui + library. + + \sa QtSingleCoreApplication +*/ + + +void QtSingleApplication::sysInit(const QString &appId) +{ + actWin = 0; + peer = new QtLocalPeer(this, appId); + connect(peer, SIGNAL(messageReceived(const QString&)), SIGNAL(messageReceived(const QString&))); +} + + +/*! + Creates a QtSingleApplication object.
