_Evgeniy Bazhenov_
__3.0.7a__
----------
* Fixed compilation error with Mingw32 in MXE thanks to Vitaly Tonkacheyev.

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__
----------
* Allows the application path and version to be excluded from the server name
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
=================
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 <QApplication>
#include <SingleApplication.h>
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.

`The MIT License (MIT)` with the exception of the Qt calculator examples which

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 <SomeClass>
or alternatively, in pre-Qt 4 style:
#include <some-class.h>
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! :)

<h2>Description</h2>
<p>The <a href="qtsingleapplication.html">QtSingleApplication</a> component provides support for applications that can be only started once per user.</p>
<p>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&#x2e; loading a file, in that instance.</p>
<p>The <a href="qtsingleapplication.html">QtSingleApplication</a> class provides an interface to detect a running instance, and to send command strings to that instance. For console (non-GUI) applications, the <a href="qtsinglecoreapplication.html">QtSingleCoreApplication</a> variant is provided, which avoids dependency on <a href="http://qt.nokia.com/doc/4.6/qtgui.html">QtGui</a>.</p>

<p>If the message could not be sent the application starts up. Note that <tt>false</tt> is passed to the call to setActivationWindow() to prevent automatic activation for every message received, e.g&#x2e; 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 <a href="qtsingleapplication.html">QtSingleApplication</a>'s activateWindow() slot.</p>

<p>The application in this example has a log-view that displays messages sent by further instances of the same application.</p>
<p>The example demonstrates the use of the <a href="qtsingleapplication.html">QtSingleApplication</a> 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 <a href="http://qt.nokia.com/doc/4.6/qtextedit.html">QTextEdit</a> log.</p>

<h2>Detailed Description</h2>
<p>The QtSingleApplication class provides an API to detect and communicate with running instances of an application.</p>
<p>This class allows you to create applications where only one instance should be running at a time. I.e&#x2e;, 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.</p>
<p>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.</p>
<p>The application should create the QtSingleApplication object early in the startup phase, and call <a href="qtsingleapplication.html#isRunning">isRunning</a>() to find out if another instance of this
application is already running. If <a href="qtsingleapplication.html#isRunning">isRunning</a>() 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 <a href="http://qt.nokia.com/doc/4.6/qapplication.html#exec">exec</a>(), as normal.</p>
<p>The <a href="qtsingleapplication.html#messageReceived">messageReceived</a>() 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 <a href="qtsingleapplication.html#setActivationWindow">setActivationWindow</a>() function and the <a href="qtsingleapplication.html#activateWindow">activateWindow</a>() slot.</p>
<p>If <a href="qtsingleapplication.html#isRunning">isRunning</a>() returns true, another instance is already running. It may be alerted to the fact that another instance has started by using
the <a href="qtsingleapplication.html#sendMessage">sendMessage</a>() function. Also data such as startup parameters (e.g&#x2e; 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).</p>
<p>If <a href="qtsingleapplication.html#isRunning">isRunning</a>() returns true, but <a href="qtsingleapplication.html#sendMessage">sendMessage</a>() fails, that is an indication that the running instance is frozen.</p>
<p>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).</p>
<pre><span class="comment"> // Original</span>
int main(int argc, char **argv)
{
QApplication app(argc, argv);
MyMainWidget mmw;
mmw.show();
return app.exec();
}
<span class="comment"> // Single instance</span>
int main(int argc, char **argv)
{
QtSingleApplication app(argc, argv);
if (app.isRunning())
return !app.sendMessage(someDataString);
MyMainWidget mmw;
app.setActivationWindow(&amp;mmw);
mmw.show();
return app.exec();
}</pre>
<p>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 <a href="qtsingleapplication.html#isRunning">isRunning</a>() or <a href="qtsingleapplication.html#sendMessage">sendMessage</a>() will assume the role as the new running instance.</p>
<p>For console (non-GUI) applications, <a href="qtsinglecoreapplication.html">QtSingleCoreApplication</a> may be used instead of this class, to avoid the dependency on the <a href="http://qt.nokia.com/doc/4.6/qtgui.html">QtGui</a> library.</p>

<h3 class="fn"><a name="activateWindow"></a>void QtSingleApplication::activateWindow ()&nbsp;&nbsp;<tt> [slot]</tt></h3>
<p>De-minimizes, raises, and activates this application's activation window. This function does nothing if no activation window has been set.</p>
<p>This is a convenience function to show the user that this application instance has been activated when he has tried to start another instance.</p>
<p>This function should typically be called in response to the <a href="qtsingleapplication.html#messageReceived">messageReceived</a>() signal. By default, that will happen automatically, if an activation window has been set.</p>
<p>See also <a href="qtsingleapplication.html#setActivationWindow">setActivationWindow</a>(), <a href="qtsingleapplication.html#messageReceived">messageReceived</a>(), and <a href="qtsingleapplication-obsolete.html#initialize" class="obsolete">initialize</a>().</p>
<h3 class="fn"><a name="activationWindow"></a><a href="http://qt.nokia.com/doc/4.6/qwidget.html">QWidget</a> * QtSingleApplication::activationWindow () const</h3>
<p>Returns the applications activation window if one has been set by calling <a href="qtsingleapplication.html#setActivationWindow">setActivationWindow</a>(), otherwise returns 0.</p>
<p>See also <a href="qtsingleapplication.html#setActivationWindow">setActivationWindow</a>().</p>
<h3 class="fn"><a name="id"></a><a href="http://qt.nokia.com/doc/4.6/qstring.html">QString</a> QtSingleApplication::id () const</h3>
<p>Returns the application identifier. Two processes with the same identifier will be regarded as instances of the same application.</p>
<h3 class="fn"><a name="isRunning"></a>bool QtSingleApplication::isRunning ()</h3>
<p>Returns true if another instance of this application is running; otherwise false.</p>
<p>This function does not find instances of this application that are being run by a different user (on Windows: that are running in another session).</p>
<p>See also <a href="qtsingleapplication.html#sendMessage">sendMessage</a>().</p>
<h3 class="fn"><a name="messageReceived"></a>void QtSingleApplication::messageReceived ( const <a href="http://qt.nokia.com/doc/4.6/qstring.html">QString</a> &amp; <i>message</i> )&nbsp;&nbsp;<tt> [signal]</tt></h3>
<p>This signal is emitted when the current instance receives a <i>message</i> from another instance of this application.</p>
<p>See also <a href="qtsingleapplication.html#sendMessage">sendMessage</a>(), <a href="qtsingleapplication.html#setActivationWindow">setActivationWindow</a>(), and <a href="qtsingleapplication.html#activateWindow">activateWindow</a>().</p>
<h3 class="fn"><a name="sendMessage"></a>bool QtSingleApplication::sendMessage ( const <a href="http://qt.nokia.com/doc/4.6/qstring.html">QString</a> &amp; <i>message</i>, int <i>timeout</i> = 5000 )&nbsp;&nbsp;<tt> [slot]</tt></h3>
<p>Tries to send the text <i>message</i> to the currently running instance. The <a href="qtsingleapplication.html">QtSingleApplication</a> object in the running instance will emit the <a href="qtsingleapplication.html#messageReceived">messageReceived</a>() signal when it receives the message.</p>
<p>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 <i>timeout</i> milliseconds, this function return false.</p>
<p>See also <a href="qtsingleapplication.html#isRunning">isRunning</a>() and <a href="qtsingleapplication.html#messageReceived">messageReceived</a>().</p>
<h3 class="fn"><a name="setActivationWindow"></a>void QtSingleApplication::setActivationWindow ( <a href="http://qt.nokia.com/doc/4.6/qwidget.html">QWidget</a> * <i>aw</i>, bool <i>activateOnMessage</i> = true )</h3>
<p>Sets the activation window of this application to <i>aw</i>. The activation window is the widget that will be activated by <a href="qtsingleapplication.html#activateWindow">activateWindow</a>(). This is typically the application's main window.</p>
<p>If <i>activateOnMessage</i> is true (the default), the window will be activated automatically every time a message is received, just prior to the <a href="qtsingleapplication.html#messageReceived">messageReceived</a>() signal being emitted.</p>
<p>See also <a href="qtsingleapplication.html#activationWindow">activationWindow</a>(), <a href="qtsingleapplication.html#activateWindow">activateWindow</a>(), and <a href="qtsingleapplication.html#messageReceived">messageReceived</a>().</p>

<p>This example shows how to use the single-application functionality in a console application. It does not require the <tt>QtGui</tt> library at all.</p>
<p>The only differences from the GUI application usage demonstrated in the other examples are:</p>
<p>1) The <tt>.pro</tt> file should include <tt>qtsinglecoreapplication.pri</tt> instead of <tt>qtsingleapplication.pri</tt></p>
<p>2) The class name is <tt>QtSingleCoreApplication</tt> instead of <tt>QtSingleApplication</tt>.</p>
<p>3) No calls are made regarding window activation, for obvious reasons.</p>

<h2>Detailed Description</h2>
<p>A variant of the <a href="qtsingleapplication.html">QtSingleApplication</a> class for non-GUI applications.</p>
<p>This class is a variant of <a href="qtsingleapplication.html">QtSingleApplication</a> suited for use in console (non-GUI) applications. It is an extension of <a href="http://qt.nokia.com/doc/4.6/qcoreapplication.html">QCoreApplication</a> (instead of <a href="http://qt.nokia.com/doc/4.6/qapplication.html">QApplication</a>). It does not require the <a href="http://qt.nokia.com/doc/4.6/qtgui.html">QtGui</a> library.</p>
<p>The API and usage is identical to <a href="qtsingleapplication.html">QtSingleApplication</a>, except that functions relating to the &quot;activation window&quot; are not present, for obvious reasons. Please refer to the <a href="qtsingleapplication.html">QtSingleApplication</a> documentation for explanation of the usage.</p>
<p>A QtSingleCoreApplication instance can communicate to a <a href="qtsingleapplication.html">QtSingleApplication</a> 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.</p>
<p>See also <a href="qtsingleapplication.html">QtSingleApplication</a>.</p>

\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.

\title A non-GUI example
This example shows how to use the single-application functionality
in a console application. It does not require the \c QtGui library
at all.
The only differences from the GUI application usage demonstrated
in the other examples are:
1) The \c.pro file should include \c qtsinglecoreapplication.pri
instead of \c qtsingleapplication.pri
2) The class name is \c QtSingleCoreApplication instead of \c
QtSingleApplication.
3) No calls are made regarding window activation, for obvious reasons.

\title Loading Documents
The application in this example loads or prints the documents
passed as commandline parameters to further instances of this
application.
\quotefromfile loader/main.cpp
\printuntil };
The user interface in this application is a QMainWindow subclass
with a QMdiArea as the central widget. It implements a slot
\c handleMessage() that will be connected to the messageReceived()
signal of the QtSingleApplication class.
\printuntil }
The MainWindow constructor creates a minimal user interface.
\printto case Print:
The handleMessage() slot interprets the message passed in as a
filename that can be prepended with \e /print to indicate that
the file should just be printed rather than loaded.
\printto #include
Loading the file will also activate the window.
\printto mw
The \c 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.
\printuntil }
If the message could not be sent the application starts up. Note
that \c 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.

\title A Trivial Example
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.
\quotefromfile trivial/main.cpp
\printuntil instance
The example has only the \c main entry point function.
A QtSingleApplication object is created immediately.
\printuntil return
If another instance of this application is already running,
sendMessage() will succeed, and this instance just exits
immediately.
\printuntil show()
Otherwise the instance continues as normal and creates the
user interface.
\printuntil return instance.exec();
The \c logview object is also set as the application's activation
window. Every time a message is received, the window will be raised
and activated automatically.
The messageReceived() signal is also connected to the QTextEdit's
append() slot. Every message received from further instances of
this application will be displayed in the log.
Finally the event loop is entered.

[dWIP] UKUI Search is a user-wide desktop search feature of UKUI desktop environment.
## 简介
狭义上的ukui-search指ukui桌面环境中的全局搜索应用，目前最新版本为3.22.x.x。全局搜索应用提供了本地文件、文本内容、应用、设置项、便签等聚合搜索功能，基于其文件索引功能，可以为用户提供快速准确的搜索体验。
狭义上的ukui-search指ukui桌面环境中的全局搜索应用，目前最新版本为4.0.x.x。全局搜索应用提供了本地文件、文本内容、应用、设置项、便签等聚合搜索功能，基于其文件索引功能，可以为用户提供快速准确的搜索体验。
广义的ukui-search除了包括全局搜索应用，还包括在ukui桌面环境中的本地搜索服务以及其开发接口。基于文建索引服务，应用搜索数据服务等基础数据源服务，可以提供基于C++接口的搜索功能，应用开发者可以通过引用动态库的形式直接使用其搜索功能。除此之外，ukui桌面环境搜索服务还提供了一组基于Qt插件框架的插件接口，用户可以通过继承接口以实现搜索功能的扩展。
以下提到的ukui-search如无说明均指后者。

## 原理与功能特点
全局搜索支持控制面板设置项搜索，应用搜索，文件搜索，便签本搜索。支持名称，拼音，或拼音首字母搜索（文本内容搜索和便签本搜索不支持拼音搜索）。其中，设置项搜索通过读取控制面板提供的配置文件实现，打开对应的控制面板页面也依赖与控制面板提供的命令行；应用搜索分为本地已安装应用（包括安卓兼容应用）和软件商店已上架的在线应用，在线应用的搜索和跳转安装通过软件商店提供的接口实现。所以，当怀疑搜索的设置搜索或应用搜索有问题时，可以直接测试控制面板或软件商店对应的接口。

文件搜索分为文件名（文件夹名）搜索和文本内容搜索。文件搜索有两种模式：`直接搜索`和`建立索引搜索`。

+ 索引搜索：搜索通过遍历文件系统建立数据库（需要消耗一定的时间和资源），搜索时直接对数据库进行搜索，可以实现毫秒级的搜索响应，建立索引的过程中，搜索结果可能不全或者搜不出结果。
首次打开索引时，ukui-search-service进程会新建两个数据库分别存储基础索引信息（用于文件名搜索）和文本内容索引信息（用于文本内容搜索），完成首次索引后，索引服务会依赖inotify机制进行实时监听更新。索引关闭再打开或重启服务时，索引服务会对遍历文件并对数据库进行校验以增量更新。
索引数据库会基于文件系统监听进行实时更新。但是由于解析文本需要时间，所以大文件的索引新可能会有短暂的延迟。由于各种意外原因，比如索引更新过程中掉电关机，可能会导致索引损坏，此时搜索在下次开机时会重新建立索引来保证正常的文件搜索功能。基于机器配置和本地文件的数量，大小以及种类，索引重建的时间可以从几秒到数分钟不等。
搜索目录可以在控制面板中手动配置，目前索引已经支持外接设备。
索引搜索支持文本内容搜索，基本原理可以参考 [倒排索引与优麒麟的文件搜索](https://docs.qq.com/doc/DU0p0S1lRelp2aW1y) 。建立索引时，搜索会对常用的文本文件进行解析，提取关键词存入数据库。搜索时，用户输入的文本也会被提取关键词，和数据库中的关键词进行匹配， 所以文本索引并不能保证你搜索一个文本文件里的任意内容都能搜出这个文件，这也不是普遍的应用场景。搜索输入的文本中必须要包含【关键词】才可以。比如你搜索一个‘的’，由于‘的’并不是任何文件的关键词，所以并不会有搜索到任何文件。事实上，我们有一个停用词词库，专门用来排除‘我’‘的’于是‘等等基本上在每个文档都会出现的一些无用词。目前，搜索支持解析的文件格式有：docx，pptx, xlsx, txt(大部分编码格式), doc, dot, wps, ppt, pps, dps, et, xls, pdf，uof，uot，uos，uop，ofd以上格式均不支持加密文件的解析，此外，文件索引支持图片ocr提取文字，所以你也可以通过图片中的文字搜索到图片（就像文档一样），支持的图片格式：png，bmp，gif，tif，tiff，webp，jpe，jpg，jpeg。
> 注意：应用的.desktop文件并不是应用本身或者“快捷方式”，对于搜索来说它只是一个文件，所以搜索desktop文件的名字并不能搜出这个应用，除非它恰好和应用重名。另外，在文件搜索中显示的dekstop文件并不会以应用的形式显示，而是显示它本来的样子——一个文件。

## 调试
ukui-search目前并未采用ukui-log4qt模块的日志功能。如需调试，可在以下目录新建`ukui-search.log`、`ukui-search-service.log`以及`ukui-search-app-data-service.log`文件，分别对应全局搜索GUI应用，全局搜索文件索引服务和应用数据服务。新建日志文件后，日志会自动打印到对应额文件中，但目前日志没有自动备份或删除机制。
