-----------
-
-* Removed Microsoft Windows specific code for getting username due to
- multiple problems and compiler differences on Windows platforms. On
- Windows the shared memory block in User mode now includes the user's
- home path (which contains the user's username).
-
-* Explicitly getting absolute path of the user's home directory as on Unix
- a relative path (`~`) may be returned.
-
-__3.0.2a__
-----------
-
-* Fixed bug on Windows when username containing wide characters causes the
- library to crash.
-
- _Le Liu_
-
-__3.0.1a__
-----------

- hash. The following flags were added for this purpose:
- * `SingleApplication::Mode::ExcludeAppVersion`
- * `SingleApplication::Mode::ExcludeAppPath`
-* Allow a non elevated process to connect to a local server created by an
- elevated process run by the same user on Windows
-* Fixes a problem with upper case letters in paths on Windows
-
- _Le Liu_
-
-__v3.0a__
----------
-
-* Deprecated secondary instances count.
-* Added a sendMessage() method to send a message to the primary instance.
-* Added a receivedMessage() signal, emitted when a message is received from a
- secondary instance.
-* The SingleApplication constructor's third parameter is now a bool
- specifying if the current instance should be allowed to run as a secondary
- instance if there is already a primary instance.
-* The SingleApplication constructor accept a fourth parameter specifying if
- the SingleApplication block should be User-wide or System-wide.
-* SingleApplication no longer relies on `applicationName` and
- `organizationName` to be set. It instead concatenates all of the following
- data and computes a `SHA256` hash which is used as the key of the
- `QSharedMemory` block and the `QLocalServer`. Since at least
- `applicationFilePath` is always present there is no need to explicitly set
- any of the following prior to initialising `SingleApplication`.
- * `QCoreApplication::applicationName`
- * `QCoreApplication::applicationVersion`
- * `QCoreApplication::applicationFilePath`
- * `QCoreApplication::organizationName`
- * `QCoreApplication::organizationDomain`
- * User name or home directory path if in User mode
-* The primary instance is no longer notified when a secondary instance had
- been started by default. A `Mode` flag for this feature exists.
-* Added `instanceNumber()` which represents a unique identifier for each
- secondary instance started. When called from the primary instance will
- return `0`.
-
-__v2.4__
---------
-
-* Stability improvements
-* Support for secondary instances.
-* The library now recovers safely after the primary process has crashed
-and the shared memory had not been deleted.
-
-__v2.3__
---------
-
-* Improved pimpl design and inheritance safety.
-
- _Vladislav Pyatnichenko_
-
-__v2.2__
---------
-
-* The `QAPPLICATION_CLASS` macro can now be defined in the file including the
-Single Application header or with a `DEFINES+=` statement in the project file.
-
-__v2.1__
---------
-
-* A race condition can no longer occur when starting two processes nearly
- simultaneously.
-
- Fix issue [#3](https://github.com/itay-grudev/SingleApplication/issues/3)
-
-__v2.0__
---------
-
-* SingleApplication is now being passed a reference to `argc` instead of a
- copy.
-
- Fix issue [#1](https://github.com/itay-grudev/SingleApplication/issues/1)
-
-* Improved documentation.

-SingleApplication
-=================
-
-This is a replacement of the QtSingleApplication for `Qt5`.
-
-Keeps the Primary Instance of your Application and kills each subsequent
-instances. It can (if enabled) spawn secondary (non-related to the primary)
-instances and can send data to the primary instance from secondary instances.
-
-Usage
------
-
-The `SingleApplication` class inherits from whatever `Q[Core|Gui]Application`
-class you specify via the `QAPPLICATION_CLASS` macro (`QCoreApplication` is the
-default). Further usage is similar to the use of the `Q[Core|Gui]Application`
-classes.
-
-The library sets up a `QLocalServer` and a `QSharedMemory` block. The first
-instance of your Application is your Primary Instance. It would check if the
-shared memory block exists and if not it will start a `QLocalServer` and listen
-for connections. Each subsequent instance of your application would check if the
-shared memory block exists and if it does, it will connect to the QLocalServer
-to notify the primary instance that a new instance had been started, after which
-it would terminate with status code `0`. In the Primary Instance
-`SingleApplication` would emit the `instanceStarted()` signal upon detecting
-that a new instance had been started.
-
-The library uses `stdlib` to terminate the program with the `exit()` function.
-
-You can use the library as if you use any other `QCoreApplication` derived
-class:
-
-```cpp
-#include
-#include
-
-int main( int argc, char* argv[] )
-{
- SingleApplication app( argc, argv );
-
- return app.exec();
-}
-```
-
-To include the library files I would recommend that you add it as a git
-submodule to your project and include it's contents with a `.pri` file. Here is
-how:
-
-```bash
-git submodule add git@github.com:itay-grudev/SingleApplication.git singleapplication
-```
-
-**Qmake:**
-
-Then include the `singleapplication.pri` file in your `.pro` project file.
-
-```qmake
-include(singleapplication/singleapplication.pri)
-DEFINES += QAPPLICATION_CLASS=QApplication
-```
-
-**CMake:**
-
-Then include the subdirectory in your `CMakeLists.txt` project file.
-
-```cmake
-set(QAPPLICATION_CLASS QApplication CACHE STRING "Inheritance class for SingleApplication")
-add_subdirectory(src/third-party/singleapplication)
-```
-
-Also don't forget to specify which `QCoreApplication` class your app is using if it
-is not `QCoreApplication` as in examples above.
-
-The `Instance Started` signal
-------------------------
-
-The SingleApplication class implements a `instanceStarted()` signal. You can
-bind to that signal to raise your application's window when a new instance had
-been started, for example.
-
-```cpp
-// window is a QWindow instance
-QObject::connect(
- &app,
- &SingleApplication::instanceStarted,
- &window,
- &QWindow::raise
-);
-```
-
-Using `SingleApplication::instance()` is a neat way to get the
-`SingleApplication` instance for binding to it's signals anywhere in your
-program.
-
-__Note:__ On Windows the ability to bring the application windows to the
-foreground is restricted. See [Windows specific implementations](Windows.md)
-for a workaround and an example implementation.
-
-
-Secondary Instances
--------------------
-
-If you want to be able to launch additional Secondary Instances (not related to
-your Primary Instance) you have to enable that with the third parameter of the
-`SingleApplication` constructor. The default is `false` meaning no Secondary
-Instances. Here is an example of how you would start a Secondary Instance send
-a message with the command line arguments to the primary instance and then shut
-down.
-
-```cpp
-int main(int argc, char *argv[])
-{
- SingleApplication app( argc, argv, true );
-
- if( app.isSecondary() ) {
- app.sendMessage( app.arguments().join(' ')).toUtf8() );
- app.exit( 0 );
- }
-
- return app.exec();
-}
-```
-
-*__Note:__ A secondary instance won't cause the emission of the
-`instanceStarted()` signal by default. See `SingleApplication::Mode` for more
-details.*
-
-You can check whether your instance is a primary or secondary with the following
-methods:
-
-```cpp
-app.isPrimary();
-// or
-app.isSecondary();
-```
-
-*__Note:__ If your Primary Instance is terminated a newly launched instance
-will replace the Primary one even if the Secondary flag has been set.*
-
-API
----
-
-### Members
-
-```cpp
-SingleApplication::SingleApplication( int &argc, char *argv[], bool allowSecondary = false, Options options = Mode::User, int timeout = 100 )
-```
-
-Depending on whether `allowSecondary` is set, this constructor may terminate
-your app if there is already a primary instance running. Additional `Options`
-can be specified to set whether the SingleApplication block should work
-user-wide or system-wide. Additionally the `Mode::SecondaryNotification` may be
-used to notify the primary instance whenever a secondary instance had been
-started (disabled by default). `timeout` specifies the maximum time in
-milliseconds to wait for blocking operations.
-
-*__Note:__ `argc` and `argv` may be changed as Qt removes arguments that it
-recognizes.*
-
-*__Note:__ `Mode::SecondaryNotification` only works if set on both the primary
-and the secondary instance.*
-
-*__Note:__ Operating system can restrict the shared memory blocks to the same
-user, in which case the User/System modes will have no effect and the block will
-be user wide.*
-
----
-
-```cpp
-bool SingleApplication::sendMessage( QByteArray message, int timeout = 100 )
-```
-
-Sends `message` to the Primary Instance. Uses `timeout` as a the maximum timeout
-in milliseconds for blocking functions
-
----
-
-```cpp
-bool SingleApplication::isPrimary()
-```
-
-Returns if the instance is the primary instance.
-
----
-
-```cpp
-bool SingleApplication::isSecondary()
-```
-Returns if the instance is a secondary instance.
-
----
-
-```cpp
-quint32 SingleApplication::instanceId()
-```
-
-Returns a unique identifier for the current instance.
-
----
-
-```cpp
-qint64 SingleApplication::primaryPid()
-```
-
-Returns the process ID (PID) of the primary instance.
-
-### Signals
-
-```cpp
-void SingleApplication::instanceStarted()
-```
-
-Triggered whenever a new instance had been started, except for secondary
-instances if the `Mode::SecondaryNotification` flag is not specified.
-
----
-
-```cpp
-void SingleApplication::receivedMessage( quint32 instanceId, QByteArray message )
-```
-
-Triggered whenever there is a message received from a secondary instance.
-
----
-
-### Flags
-
-```cpp
-enum SingleApplication::Mode
-```
-
-* `Mode::User` - The SingleApplication block should apply user wide. This adds
- user specific data to the key used for the shared memory and server name.
- This is the default functionality.
-* `Mode::System` – The SingleApplication block applies system-wide.
-* `Mode::SecondaryNotification` – Whether to trigger `instanceStarted()` even
- whenever secondary instances are started.
-* `Mode::ExcludeAppPath` – Excludes the application path from the server name
- (and memory block) hash.
-* `Mode::ExcludeAppVersion` – Excludes the application version from the server
- name (and memory block) hash.
-
-*__Note:__ `Mode::SecondaryNotification` only works if set on both the primary
-and the secondary instance.*
-
-*__Note:__ Operating system can restrict the shared memory blocks to the same
-user, in which case the User/System modes will have no effect and the block will
-be user wide.*
-
----
-
-Versioning
-----------
-
-Each major version introduces either very significant changes or is not
-backwards compatible with the previous version. Minor versions only add
-additional features, bug fixes or performance improvements and are backwards
-compatible with the previous release. See [`CHANGELOG.md`](CHANGELOG.md) for
-more details.
-
-Implementation
---------------
-
-The library is implemented with a QSharedMemory block which is thread safe and
-guarantees a race condition will not occur. It also uses a QLocalSocket to
-notify the main process that a new instance had been spawned and thus invoke the
-`instanceStarted()` signal and for messaging the primary instance.
-
-Additionally the library can recover from being forcefully killed on *nix
-systems and will reset the memory block given that there are no other
-instances running.
-
-License
--------
-This library and it's supporting documentation are released under
-`The MIT License (MIT)` with the exception of the Qt calculator examples which
-is distributed under the BSD license.

-Windows Specific Implementations
-================================
-
-Setting the foreground window
------------------------------
-
-In the `instanceStarted()` example in the `README` we demonstrated how an
-application can bring it's primary instance window whenever a second copy
-of the application is started.
-
-On Windows the ability to bring the application windows to the foreground is
-restricted, see [`AllowSetForegroundWindow()`][AllowSetForegroundWindow] for more
-details.
-
-The background process (the primary instance) can bring its windows to the
-foreground if it is allowed by the current foreground process (the secondary
-instance). To bypass this `SingleApplication` must be initialized with the
-`allowSecondary` parameter set to `true` and the `options` parameter must
-include `Mode::SecondaryNotification`, See `SingleApplication::Mode` for more
-details.
-
-Here is an example:
-
-```cpp
-if( app.isSecondary() ) {
- // This API requires LIBS += User32.lib to be added to the project
- AllowSetForegroundWindow( DWORD( app.primaryPid() ) );
-}
-
-if( app.isPrimary() ) {
- QObject::connect(
- &app,
- &SingleApplication::instanceStarted,
- this,
- &App::instanceStarted
- );
-}
-```
-
-```cpp
-void App::instanceStarted() {
- QApplication::setActiveWindow( [window/widget to set to the foreground] );
-}
-```

+INSTALLATION INSTRUCTIONS
+
+These instructions refer to the package you are installing as
+some-package.tar.gz or some-package.zip. The .zip file is intended for use
+on Windows.
+
+The directory you choose for the installation will be referred to as
+your-install-dir.
+
+Note to Qt Visual Studio Integration users: In the instructions below,
+instead of building from command line with nmake, you can use the menu
+command 'Qt->Open Solution from .pro file' on the .pro files in the
+example and plugin directories, and then build from within Visual
+Studio.
+
+Unpacking and installation
+--------------------------
+
+1. Unpacking the archive (if you have not done so already).
+
+ On Unix and Mac OS X (in a terminal window):
+
+ cd your-install-dir
+ gunzip some-package.tar.gz
+ tar xvf some-package.tar
+
+ This creates the subdirectory some-package containing the files.
+
+ On Windows:
+
+ Unpack the .zip archive by right-clicking it in explorer and
+ choosing "Extract All...". If your version of Windows does not
+ have zip support, you can use the infozip tools available
+ from www.info-zip.org.
+
+ If you are using the infozip tools (in a command prompt window):
+ cd your-install-dir
+ unzip some-package.zip
+
+2. Configuring the package.
+
+ The configure script is called "configure" on unix/mac and
+ "configure.bat" on Windows. It should be run from a command line
+ after cd'ing to the package directory.
+
+ You can choose whether you want to use the component by including
+ its source code directly into your project, or build the component
+ as a dynamic shared library (DLL) that is loaded into the
+ application at run-time. The latter may be preferable for
+ technical or licensing (LGPL) reasons. If you want to build a DLL,
+ run the configure script with the argument "-library". Also see
+ the note about usage below.
+
+ (Components that are Qt plugins, e.g. styles and image formats,
+ are by default built as a plugin DLL.)
+
+ The configure script will prompt you in some cases for further
+ information. Answer these questions and carefully read the license text
+ before accepting the license conditions. The package cannot be used if
+ you do not accept the license conditions.
+
+3. Building the component and examples (when required).
+
+ If a DLL is to be built, or if you would like to build the
+ examples, next give the commands
+
+ qmake
+ make [or nmake if your are using Microsoft Visual C++]
+
+ The example program(s) can be found in the directory called
+ "examples" or "example".
+
+ Components that are Qt plugins, e.g. styles and image formats, are
+ ready to be used as soon as they are built, so the rest of this
+ installation instruction can be skipped.
+
+4. Building the Qt Designer plugin (optional).
+
+ Some of the widget components are provided with plugins for Qt
+ Designer. To build and install the plugin, cd into the
+ some-package/plugin directory and give the commands
+
+ qmake
+ make [or nmake if your are using Microsoft Visual C++]
+
+ Restart Qt Designer to make it load the new widget plugin.
+
+ Note: If you are using the built-in Qt Designer from the Qt Visual
+ Studio Integration, you will need to manually copy the plugin DLL
+ file, i.e. copy
+ %QTDIR%\plugins\designer\some-component.dll
+ to the Qt Visual Studio Integration plugin path, typically:
+ C:\Program Files\Trolltech\Qt VS Integration\plugins
+
+ Note: If you for some reason are using a Qt Designer that is built
+ in debug mode, you will need to build the plugin in debug mode
+ also. Edit the file plugin.pro in the plugin directory, changing
+ 'release' to 'debug' in the CONFIG line, before running qmake.
+
+
+
+Solutions components are intended to be used directly from the package
+directory during development, so there is no 'make install' procedure.
+
+
+Using a component in your project
+---------------------------------
+
+To use this component in your project, add the following line to the
+project's .pro file (or do the equivalent in your IDE):
+
+ include(your-install-dir/some-package/src/some-package.pri)
+
+This adds the package's sources and headers to the SOURCES and HEADERS
+project variables respectively (or, if the component has been
+configured as a DLL, it adds that library to the LIBS variable), and
+updates INCLUDEPATH to contain the package's src
+directory. Additionally, the .pri file may include some dependencies
+needed by the package.
+
+To include a header file from the package in your sources, you can now
+simply use:
+
+ #include
+
+or alternatively, in pre-Qt 4 style:
+
+ #include
+
+Refer to the documentation to see the classes and headers this
+components provides.
+
+
+
+Install documentation (optional)
+--------------------------------
+
+The HTML documentation for the package's classes is located in the
+your-install-dir/some-package/doc/html/index.html. You can open this
+file and read the documentation with any web browser.
+
+To install the documentation into Qt Assistant (for Qt version 4.4 and
+later):
+
+1. In Assistant, open the Edit->Preferences dialog and choose the
+ Documentation tab. Click the Add... button and select the file
+ your-install-dir/some-package/doc/html/some-package.qch
+
+For Qt versions prior to 4.4, do instead the following:
+
+1. The directory your-install-dir/some-package/doc/html contains a
+ file called some-package.dcf. Execute the following commands in a
+ shell, command prompt or terminal window:
+
+ cd your-install-dir/some-package/doc/html/
+ assistant -addContentFile some-package.dcf
+
+The next time you start Qt Assistant, you can access the package's
+documentation.
+
+
+Removing the documentation from assistant
+-----------------------------------------
+
+If you have installed the documentation into Qt Assistant, and want to uninstall it, do as follows, for Qt version 4.4 and later:
+
+1. In Assistant, open the Edit->Preferences dialog and choose the
+ Documentation tab. In the list of Registered Documentation, select
+ the item com.nokia.qtsolutions.some-package_version, and click
+ the Remove button.
+
+For Qt versions prior to 4.4, do instead the following:
+
+1. The directory your-install-dir/some-package/doc/html contains a
+ file called some-package.dcf. Execute the following commands in a
+ shell, command prompt or terminal window:
+
+ cd your-install-dir/some-package/doc/html/
+ assistant -removeContentFile some-package.dcf
+
+
+
+Using the component as a DLL
+----------------------------
+
+1. Normal components
+
+ The shared library (DLL) is built and placed in the
+ some-package/lib directory. It is intended to be used directly
+ from there during development. When appropriate, both debug and
+ release versions are built, since the run-time linker will in some
+ cases refuse to load a debug-built DLL into a release-built
+ application or vice versa.
+
+ The following steps are taken by default to help the dynamic
+ linker to locate the DLL at run-time (during development):
+
+ Unix: The some-package.pri file will add linker instructions to
+ add the some-package/lib directory to the rpath of the
+ executable. (When distributing, or if your system does not support
+ rpath, you can copy the shared library to another place that is
+ searched by the dynamic linker, e.g. the "lib" directory of your
+ Qt installation.)
+
+ Mac: The full path to the library is hardcoded into the library
+ itself, from where it is copied into the executable at link time,
+ and ready by the dynamic linker at run-time. (When distributing,
+ you will want to edit these hardcoded paths in the same way as for
+ the Qt DLLs. Refer to the document "Deploying an Application on
+ Mac OS X" in the Qt Reference Documentation.)
+
+ Windows: the .dll file(s) are copied into the "bin" directory of
+ your Qt installation. The Qt installation will already have set up
+ that directory to be searched by the dynamic linker.
+
+
+2. Plugins
+
+ For Qt Solutions plugins (e.g. image formats), both debug and
+ release versions of the plugin are built by default when
+ appropriate, since in some cases the release Qt library will not
+ load a debug plugin, and vice versa. The plugins are automatically
+ copied into the plugins directory of your Qt installation when
+ built, so no further setup is required.
+
+ Plugins may also be built statically, i.e. as a library that will be
+ linked into your application executable, and so will not need to
+ be redistributed as a separate plugin DLL to end users. Static
+ building is required if Qt itself is built statically. To do it,
+ just add "static" to the CONFIG variable in the plugin/plugin.pro
+ file before building. Refer to the "Static Plugins" section in the
+ chapter "How to Create Qt Plugins" for explanation of how to use a
+ static plugin in your application. The source code of the example
+ program(s) will also typically contain the relevant instructions
+ as comments.
+
+
+
+Uninstalling
+------------
+
+ The following command will remove any fils that have been
+ automatically placed outside the package directory itself during
+ installation and building
+
+ make distclean [or nmake if your are using Microsoft Visual C++]
+
+ If Qt Assistant documentation or Qt Designer plugins have been
+ installed, they can be uninstalled manually, ref. above.
+
+
+Enjoy! :)

+ Single Application
+
+
+
+
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.
The application in this example loads or prints the documents passed as commandline parameters to further instances of this application.

+ };
+
The user interface in this application is a QMainWindow subclass with a QMdiArea as the central widget. It implements a slot handleMessage() that will be connected to the messageReceived() signal of the QtSingleApplication class.
The handleMessage() slot interprets the message passed in as a filename that can be prepended with /print to indicate that the file should just be printed rather than loaded.
#include "main.moc"
+
+ int main(int argc, char **argv)
+ {
+ QtSingleApplication instance("File loader QtSingleApplication example", argc, argv);
+ QString message;
+ for (int a = 1; a < argc; ++a) {
+ message += argv[a];
+ if (a < argc-1)
+ message += " ";
+ }
+
+ if (instance.sendMessage(message))
+ return 0;
+
The main entry point function creates a QtSingleApplication object, and creates a message to send to a running instance of the application. If the message was sent successfully the process exits immediately.
If the message could not be sent the application starts up. Note that false is passed to the call to setActivationWindow() to prevent automatic activation for every message received, e.g. when the application should just print a file. Instead, the message handling function determines whether activation is requested, and signals that by emitting the needToShow() signal. This is then simply connected directly to QtSingleApplication's activateWindow() slot.
The application in this example has a log-view that displays messages sent by further instances of the same application.
+
The example demonstrates the use of the QtSingleApplication class to detect and communicate with a running instance of the application using the sendMessage() API. The messageReceived() signal is used to display received messages in a QTextEdit log.

+ List of All Members for QtSingleApplication
+
+
+
+
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).
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.
Special constructor for X11, ref. the documentation of QApplication's corresponding constructor. The application identifier will be QCoreApplication::applicationFilePath(). dpy, argc, argv, visual, and cmap are passed on to the QApplication constructor.

De-minimizes, raises, and activates this application's activation window. This function does nothing if no activation window has been set.
+
This is a convenience function to show the user that this application instance has been activated when he has tried to start another instance.
+
This function should typically be called in response to the messageReceived() signal. By default, that will happen automatically, if an activation window has been set.
Tries to send the text message to the currently running instance. The QtSingleApplication object in the running instance will emit the messageReceived() signal when it receives the message.
+
This function returns true if the message has been sent to, and processed by, the current instance. If there is no instance currently running, or if the running instance fails to process the message within timeout milliseconds, this function return false.
Sets the activation window of this application to aw. The activation window is the widget that will be activated by activateWindow(). This is typically the application's main window.
+
If activateOnMessage is true (the default), the window will be activated automatically every time a message is received, just prior to the messageReceived() signal being emitted.

The API and usage is identical to QtSingleApplication, except that functions relating to the "activation window" are not present, for obvious reasons. Please refer to the QtSingleApplication documentation for explanation of the usage.
+
A QtSingleCoreApplication instance can communicate to a QtSingleApplication instance if they share the same application id. Hence, this class can be used to create a light-weight command-line tool that sends commands to a GUI application.
Tries to send the text message to the currently running instance. The QtSingleCoreApplication object in the running instance will emit the messageReceived() signal when it receives the message.
+
This function returns true if the message has been sent to, and processed by, the current instance. If there is no instance currently running, or if the running instance fails to process the message within timeout milliseconds, this function return false.
