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. 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.

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., 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. 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(&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="messageReceived"></a>void QtSingleApplication::messageReceived ( const <a href="http://qt.nokia.com/doc/4.6/qstring.html">QString</a> & <i>message</i> ) <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>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>

|
||||
<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>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 "activation window" 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.

\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

/*!
|

\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

\class QtSingleCoreApplication qtsinglecoreapplication.h

\brief A variant of the QtSingleApplication class for non-GUI applications.
|
||||
|
||||
This class is a variant of QtSingleApplication suited for use in
|
||||
console (non-GUI) applications. It is an extension of
|
||||
QCoreApplication (instead of QApplication). It does not require
|
||||
the QtGui library.
|
||||
|
||||
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.
