3 \title Single Application
7 The QtSingleApplication component provides support
8 for applications that can be only started once per user.
12 For some applications it is useful or even critical that they are started
13 only once by any user. Future attempts to start the application should
14 activate any already running instance, and possibly perform requested
15 actions, e.g. loading a file, in that instance.
17 The QtSingleApplication class provides an interface to detect a running
18 instance, and to send command strings to that instance.
19 For console (non-GUI) applications, the QtSingleCoreApplication variant is provided, which avoids dependency on QtGui.
