The messageReceived() + signal is used to display received messages in a QTextEdit log. + + \quotefromfile trivial/main.cpp + \printuntil instance + The example has only the \c main entry point function. + A QtSingleApplication object is created immediately. + + \printuntil return + If another instance of this application is already running, + sendMessage() will succeed, and this instance just exits + immediately. + + \printuntil show() + Otherwise the instance continues as normal and creates the + user interface. + + \printuntil return instance.exec(); + The \c logview object is also set as the application's activation + window. Every time a message is received, the window will be raised + and activated automatically. + + The messageReceived() signal is also connected to the QTextEdit's + append() slot. Every message received from further instances of + this application will be displayed in the log. + + Finally the event loop is entered. +*/ |
