\class QtLockedFile
\brief The QtLockedFile class extends QFile with advisory locking
functions.
A file may be locked in read or write mode. Multiple instances of
\e QtLockedFile, created in multiple processes running on the same
machine, may have a file locked in read mode. Exactly one instance
may have it locked in write mode. A read and a write lock cannot
exist simultaneously on the same file.
The file locks are advisory. This means that nothing prevents
another process from manipulating a locked file using QFile or
file system functions offered by the OS. Serialization is only
guaranteed if all processes that access the file use
QLockedFile. Also, while holding a lock on a file, a process
must not open the same file again (through any API), or locks
can be unexpectedly lost.
The lock provided by an instance of \e QtLockedFile is released
whenever the program terminates. This is true even when the
program crashes and no destructors are called.
*/
/*! \enum QtLockedFile::LockMode
This enum describes the available lock modes.
\value ReadLock A read lock.
\value WriteLock A write lock.
\value NoLock Neither a read lock nor a write lock.
*/

Constructs an unlocked \e QtLockedFile object. This constructor
behaves in the same way as \e QFile::QFile().

This is identical to QFile::open(), with the one exception that the
Truncate mode flag is disallowed. Truncation would conflict with the
advisory file locking, since the file would be modified before the

after obtaining the write lock.

Obtains a lock of type \a mode. The file must be opened before it
can be locked.
If \a block is true, this function will block until the lock is
aquired. If \a block is false, this function returns \e false
immediately if the lock cannot be aquired.
If this object already has a lock of type \a mode, this function
returns \e true immediately. If this object has a lock of a
different type than \a mode, the lock is first released and then a
new lock is obtained.
This function returns \e true if, after it executes, the file is
locked by this object, and \e false otherwise.

\class QtSingleApplication qtsingleapplication.h
\brief The QtSingleApplication class provides an API to detect and
communicate with running instances of an application.
This class allows you to create applications where only one
instance should be running at a time. 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.

The API and usage is identical to QtSingleApplication, except that

obvious reasons. Please refer to the QtSingleApplication
documentation for explanation of the usage.
A QtSingleCoreApplication instance can communicate to a
