Scalable Vector Graphics (SVG) is an XML-based language for describing two-dimensional vector graphics. Qt provides classes for rendering and displaying SVG drawings in widgets and on other paint devices.
This class extends the QFile class with inter-process file locking capabilities. If an application requires that several processes should access the same file, QtLockedFile can be used to easily ensure that only one process at a time is writing to the file, and that no process is writing to it while others are reading it.

If an application requires that several processes should access the same file, QtLockedFile can be used to easily ensure that only one process at a time is writing to the file, and that no process is writing to it while others are reading it. This is a special build against Qt5.
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.
