\title Single Application
|
|
|
|
\section1 Description
|
|
|
|
The QtSingleApplication component provides support
|
|
for applications that can be only started once per user.
|
|
|
|
|
|
|
|
For some applications it is useful or even critical that they are started
|
|
only once by any user. Future attempts to start the application should
|
|
activate any already running instance, and possibly perform requested
|
|
actions, e.g. loading a file, in that instance.
|
|
|
|
The QtSingleApplication class provides an interface to detect a running
|
|
instance, and to send command strings to that instance.
|
|
For console (non-GUI) applications, the QtSingleCoreApplication variant is provided, which avoids dependency on QtGui.
