* qt/*: * dbus/qdbus.h: Sync with KDE Subversion revision 523647. Hopefully, this will be the last of the source-incompatible changes. Documentation has been improved; support for QList<basic-types> has been added; QDBusObject is gone; QDBus(Abstract)Interface is now a QObject with auto-generated meta-object; QDBusIntrospection is marked private, since QMetaObject can be used now; lots of bugfixes.

-    \page UsingAdaptors Using Adaptors
-
-    Adaptors are special classes that are attached to any QObject-derived class and provide the
-    interface to the external world using D-Bus. Adaptors are intended to be light-weight classes
-    whose main purpose is to relay calls to and from the real object, possibly validating or
-    converting the input from the external world and, thus, protecting the real object.
-
-    Unlike multiple inheritance, adaptors can be added at any time to any object (but not removed),
-    which allows for greater flexibility when exporting existing classes. Another advantage of
-    adaptors is to provide similar but not identical functionality in methods of the same name in
-    different interfaces, a case which can be quite common when adding a new version of a standard
-    interface to an object.
-
-    In order to use an adaptor, one must create a class which inherits QDBusAbstractAdaptor. Since
-    that is a standard QObject-derived class, the Q_OBJECT macro must appear in the declaration and
-    the source file must be processed with the \link moc \endlink tool. The class must also contain
-    one or more Q_CLASSINFO entries with the "D-Bus Interface" name, declaring which interfaces it
-    is exporting.
-
-    Any public slot in the class will be accessible through the bus over messages of the MethodCall
-    type. (See \link DeclaringSlots \endlink for more information). Signals in the class will be
-    automatically relayed over D-Bus. However, not all types are allowed signals or slots' parameter
-    lists: see \link AllowedParameters \endlink for more information.
-
-    Also, any property declared with Q_PROPERTY will be automatically exposed over the Properties
-    interface on D-Bus. Since the QObject property system does not allow for non-readable
-    properties, it is not possible to declare write-only properties using adaptors.

-    \page AdaptorExample Example of an interface implemented with an adaptor
-
-    A sample usage of QDBusAbstractAdaptor is as follows:
-    \code
-        class MainApplicationAdaptor: public QDBusAbstractAdaptor
-        {
-            Q_OBJECT
-            Q_CLASSINFO("D-Bus Interface", "com.example.DBus.MainApplication")
-            Q_CLASSINFO("D-Bus Interface", "org.kde.DBus.MainApplication")
-            Q_PROPERTY(QString caption READ caption WRITE setCaption)
-            Q_PROPERTY(QString organizationName READ organizationName)
-            Q_PROPERTY(QString organizationDomain READ organizationDomain)
-
-        private:
-            MyApplication *app;
-
-        public:
-            MyInterfaceAdaptor(MyApplication *application)
-                : QDBusAbstractAdaptor(application), app(application)
-            {
-                connect(application, SIGNAL(aboutToQuit()), SIGNAL(aboutToQuit());
-                connect(application, SIGNAL(focusChanged(QWidget*, QWidget*)),
-                        SLOT(focusChangedSlot(QWidget*, QWidget*)));
-            }
-
-            QString caption()
-            {
-                if (app->hasMainWindow())
-                    return app->mainWindow()->caption();
-                return QString();
-            }
-
-            void setCaption(const QString &newCaption)
-            {
-                if (app->hasMainWindow())
-                    app->mainWindow()->setCaption(newCaption);
-            }
-
-            QString organizationName()
-            {
-                return app->organizationName();
-            }
-
-            QString organizationDomain()
-            {
-                return app->organizationDomain();
-            }
-
-        public slots:
-            async void quit()
-            { app->quit(); }
-
-            void reparseConfiguration()
-            { app->reparseConfiguration(); }
-
-            QString mainWindowObject()
-            {
-                if (app->hasMainWindow())
-                    return QString("/%1/mainwindow").arg(app->applicationName());
-                return QString();
-            }
-
-            void setSessionManagement(bool enable)
-            {
-                if (enable)
-                   app->enableSessionManagement();
-                else
-                   app->disableSessionManagement();
-            }
-
-        private slots:
-            void focusChangedSlot(QWidget *, QWidget *now)
-            {
-                if (now == app->mainWindow())
-                    emit mainWindowHasFocus();
-            }
-
-        signals:
-            void aboutToQuit();
-            void mainWindowHasFocus();
-        };
-    \endcode
-
-    The code above would create an interface that could be represented more or less in the following
-    canonical representation:
-    \code
-        interface com.example.DBus.MainApplication
-        {
-            property readwrite STRING caption
-            property read STRING organizationName
-            property read STRING organizationDomain
-
-            method quit() annotation("org.freedesktop.DBus.Method.NoReply", "true")
-            method reparseConfiguration()
-            method mainWindowObject(out STRING)
-            method disableSessionManagement(in BOOLEAN enable)
-
-            signal aboutToQuit()
-            signal mainWindowHasFocus()
-        }
-
-        interface org.kde.DBus.MainApplication
-        {
-            ....
-        }
-    \endcode
-
-    This adaptor could be used in the application's constructor as follows:
-    \code
-        MyApplication::MyApplication()
-        {
-            [...]
-
-            // create the MainApplication adaptor:
-            new MainApplicationAdaptor(this);
-
-            // connect to D-Bus:
-            QDBusConnection connection = QDBusConnection::addConnection(QDBusConnection::SessionBus);
-
-            // register us as an object:
-            connection.registerObject("/MainApplication", this);
-
-            [...]
-        }
-    \endcode
-

-    The header of the example is:

-    \endcode
-
-    The code does the following:
-    - it declares the adaptor MainApplicationAdaptor, which descends from QDBusAbstractAdaptor
-    - it declares the Qt Meta Object data using the #Q_OBJECT macro
-    - it declares the names of two D-Bus interfaces it implements. Those interfaces are equal in all
-      aspects.
-*/
-
-/*!
-    \page AdaptorExampleProperties The properties
-
-    The properties are declared as follows:
-    \code
-            Q_PROPERTY(QString caption READ caption WRITE setCaption)
-            Q_PROPERTY(QString organizationName READ organizationName)
-            Q_PROPERTY(QString organizationDomain READ organizationDomain)
-    \endcode
-
-    And are implemented as follows:
-    \code
-            QString caption()
-            {
-                if (app->hasMainWindow())
-                    return app->mainWindow()->caption();
-                return QString();
-            }
-
-            void setCaption(const QString &newCaption)
-            {
-                if (app->hasMainWindow())
-                    app->mainWindow()->setCaption(newCaption);
-            }
-
-            QString organizationName()

-                return app->organizationDomain();
-            }
-    \endcode
-
-    The code declares three properties: one of them is a read-write property called "caption" of
-    string type. The other two are read-only, also of the string type.
-
-    The properties organizationName and organizationDomain are simple relays of the app object's
-    organizationName and organizationDomain properties. However, the caption property requires
-    verifying if the application has a main window associated with it: if there isn't any, the
-    caption property is empty. Note how it is possible to access data defined in other objects
-    through the getter/setter functions.

-/*!
-    \page AdaptorExampleConstructor The constructor
-
-    The constructor:
-    \code
-            MyInterfaceAdaptor(MyApplication *application)
-                : QDBusAbstractAdaptor(application), app(application)
-            {
-                connect(application, SIGNAL(aboutToQuit()), SIGNAL(aboutToQuit());
-                connect(application, SIGNAL(focusChanged(QWidget*, QWidget*)),
-                        SLOT(focusChangedSlot(QWidget*, QWidget*)));
-            }
-    \endcode
-
-    The constructor does the following:
-    - it initialises its base class (QDBusAbstractAdaptor) with the parent object it is related to.
-    - it stores the app pointer in a member variable. Note that it would be possible to access the
-      same object using the QDBusAbstractAdaptor::object() function, but it would be necessary to
-      use \a static_cast<> to properly access the methods in MyApplication that are not part of
-      QObject.
-    - it connects the application's signal \a aboutToQuit to its own signal \a aboutToQuit.
-    - it connects the application's signal \a focusChanged to a private slot to do some further
-      processing before emitting a D-Bus signal.
-
-    Note that there is no destructor in the example. An eventual destructor could be used to emit
-    one last signal before the object is destroyed, for instance.

-
-/*!
-    \page AdaptorExampleSlots Slots/methods
-
-    The public slots in the example (which will be exported as D-Bus methods) are the following:
-    \code
-        public slots:
-            async void quit()
-            { app->quit(); }
-
-            void reparseConfiguration()
-            { app->reparseConfiguration(); }
-
-            QString mainWindowObject()
-            {
-                if (app->hasMainWindow())
-                    return QString("/%1/mainwindow").arg(app->applicationName());
-                return QString();
-            }
-

-            {

-                else
-                   app->disableSessionManagement();
-            }
-    \endcode
-
-    This snippet of code defines 4 methods with different properties each:
-    - \p quit: this method takes no parameters and is defined to be asynchronous. That is, callers
-      are expected to use "fire-and-forget" mechanism when calling this method, since it provides no
-      useful reply. This is represented in D-Bus by the use of the
-      org.freedesktop.DBus.Method.NoReply annotation. See #Q_ASYNC for more information on
-      asynchronous methods
-
-    - \p reparseConfiguration: this simple method, with no input or output arguments simply relays
-      the call to the application's reparseConfiguration member function.
-
-    - \p mainWindowObject: this method takes no input parameter, but returns one string output
-      argument, containing the path to the main window object (if the application has a main
-      window), or an empty string if it has no main window. Note that this method could have also
-      been written: void mainWindowObject(QString &path).
-
-    - \p setSessionManagement: this method takes one input argument (a boolean) and, depending on
-      its value, it calls one function or another in the application.
-
-    \sa #Q_ASYNC

-
-/*!
-    \page AdaptorExampleSignals Signals
-
-    The signals in this example are defined as follows:
-    \code
-        signals:
-            void aboutToQuit();
-            void mainWindowHasFocus();
-    \endcode
-
-    However, signal definition isn't enough: signals have to be emitted. One simple way of emitting
-    signals is to connect another signal to them, so that Qt's signal handling system chains them
-    automatically. This is what is done for the \a aboutToQuit signal (see \ref
-    AdaptorExampleConstructor).
-
-    When this is the case, one can use the QDBusAbstractAdaptor::setAutoRelaySignals to
-    automatically connect every signal from the real object to the adaptor.
-
-    When simple signal-to-signal connection isn't enough, one can use a private slot do do some
-    work. This is what was done for the mainWindowHasFocus signal:
-    \code
-        private slots:
-            void focusChangedSlot(QWidget *, QWidget *now)
-            {
-                if (now == app->mainWindow())
-                    emit mainWindowHasFocus();
-            }
-    \endcode
-
-    This private slot (which will not be exported as a method via D-Bus) was connected to the
-    \a focusChanged signal in the adaptor's constructor. It is therefore able to shape the
-    application's signal into what the interface expects it to be.

-
-/*!
-    \page DeclaringSlots Declaring slots
-
-    Slots in D-Bus adaptors are declared just like normal, public slots, but their parameters must
-    follow certain rules (see \ref AllowedParameters for more information). Slots whose parameters
-    do not follow those rules or that are not public will not be accessible via D-Bus.
-
-    Slots can be of three kinds:
-    -# Asynchronous
-    -# Input-only
-    -# Input-and-output
-
-    \par Asynchronous slots
-         Asynchronous slots are those that do not normally return any reply to the caller. For that
-         reason, they cannot take any output parameters. In most cases, by the time the first line
-         of the slot is run, the caller function has already resumed working.
-
-    \par
-         However, slots must rely on that behavior. Scheduling and message-dispatching issues could
-         change the order in which the slot is run. Code intending to synchronize with the caller
-         should provide its own method of synchronization.
-
-    \par
-         Asynchronous slots are marked by the keyword \p #async or \p #Q_ASYNC in the method
-         signature, before the \p void return type and the slot name. (See the \p quit slot in the
-         \ref AdaptorExample "adaptor example").
-
-    \par Input-only slots
-         Input-only slots are normal slots that take parameters passed by value or by constant
-         reference. However, unlike asynchronous slots, the caller is usually waiting for completion
-         of the callee before resuming operation. Therefore, non-asynchronous slots should not block
-         or should state it its documentation that they may do so.
-
-    \par
-         Input-only slots have no special marking in their signature, except that they take only
-         parameters passed by value or by constant reference. Optionally, slots can take a
-         QDBusMessage parameter as a last parameter, which can be used to perform additional
-         analysis of the method call message.
-
-    \par Input and output slots
-         Like input-only slots, input-and-output slots are those that the caller is waiting for a
-         reply. Unlike input-only ones, though, this reply will contain data. Slots that output data
-         may contain non-constant references and may return a value as well. However, the output
-         parameters must all appear at the end of the argument list and may not have input arguments
-         interleaved. Optionally, a QDBusMessage argument may appear between the input and the
-         output arguments.
-
-    \note When a caller places a method call and waits for a reply, it will only wait for so long.
-         Slots intending to take a long time to complete should make that fact clear in
-         documentation so that callers properly set higher timeouts.
-
-    Method replies are generated automatically with the contents of the output parameters (if there
-    were any) by the QtDBus implementation. Slots need not worry about constructing proper
-    QDBusMessage objects and sending them over the connection.
-
-    However, the possibility of doing so remains there. Should the slot find out it needs to send a
-    special reply or even an error, it can do so by using QDBusMessage::methodReply or
-    QDBusMessage::error on the QDBusMessage parameter and send it with QDBusConnection::send. The
-    QtDBus implementation will not generate any reply if the slot did so.

-    Any signal in a class derived from QDBusAbstractAdaptor will be automatically relayed into
-    D-Bus, provided that the signal's parameters conform to certain rules (see \ref
-    AllowedParameters for more information). No special code is necessary to make this relay.
-
-    However, signals must still be emitted. The easiest way to emit an adaptor signal is to connect
-    another signal to it, so that the Qt signal/slot mechanism automatically emits the adaptor
-    signal too. This can be done in the adaptor's constructor, as has been done in the \ref
-    AdaptorExample "adaptor example".
-
-    The convenience function QDBusAbstractAdaptor::setAutoRelaySignals can also be used to connect
-    or disconnect every signal in the real object to the same signal in the adaptor. It will inspect

+    \fn QDBusMessage QDBusAbstractInterface::call(const QString &method)
+
+    Calls the method \a method on this interface and passes the parameters to this function to the
+    method.
+
+    The parameters to \c call are passed on to the remote function via D-Bus as input
+    arguments. Output arguments are returned in the QDBusMessage reply. If the reply is an error
+    reply, lastError() will also be set to the contents of the error message.
+
+    This function is implemented by actually 9 different function overloads called \c call, so you
+    can pass up to 8 parameters to your function call, which can be of any type accepted by QtDBus
+    (see the \l {allowedparameters.html}{allowed parameters} page for information on what types are
+    accepted).
+
+    It can be used the following way:
+
+    \code
+      QString value = retrieveValue();
+      QDBusMessage reply;
+
+      QDBusReply<int> api = interface->call(QLatin1String("GetAPIVersion"));
+      if (api >= 14)
+        reply = interface->call(QLatin1String("ProcessWorkUnicode"), value);
+      else
+        reply = interface->call(QLatin1String("ProcessWork"), QLatin1String("UTF-8"), value.toUtf8());
+    \endcode
+
+    This example illustrates function calling with 0, 1 and 2 parameters and illustrates different
+    parameter types passed in each (the first call to \c "ProcessWorkUnicode" will contain one
+    Unicode string, the second call to \c "ProcessWork" will contain one string and one byte array).
+        
+    \warning This function reenters the Qt event loop in order to wait for the reply, excluding user
+             input. During the wait, it may deliver signals and other method calls to your
+             application. Therefore, it must be prepared to handle a reentrancy whenever a call is
+             placed with call().

     \class QDBusInterface
-    \brief Base class for all D-Bus interfaces in the QtDBus binding, allowing access to remote interfaces.
+    \brief Proxy class for interfaces on remote objects.
 
     QDBusInterface is a generic accessor class that is used to place calls to remote objects,
     connect to signals exported by remote objects and get/set the value of remote properties. This
     class is useful for dynamic access to remote objects: that is, when you do not have a generated
     code that represents the remote interface.
 
-    Generated-code classes also derive from QDBusInterface, all methods described here are also
-    valid for generated-code classes. In addition to those described here, generated-code classes
-    provide member functions for the remote methods, which allow for compile-time checking of the
-    correct parameters and return values, as well as property type-matching and signal
-    parameter-matching.
-
     Calls are usually placed by using the call() function, which constructs the message, sends it
     over the bus, waits for the reply and decodes the reply. Signals are connected to by using the
-    connect() family of functions, whose behavior is similar to QObject::connect(). Finally,
-    properties are accessed using the property() and setProperty() functions, whose behaviour is
-    also similar to QObject::property() and QObject::setProperty().

-    \enum QDBusInterface::CallMode
-    \todo turn this into flags and add UseEventLoop/NoUseEventLoop
-
-    Specifies how a call should be placed. The valid options are:
-    \value NoWaitForReply       place the call but don't wait for the reply (the reply's contents
-                                will be discarded)
-    \value WaitForReply         place the call and wait for the method to finish before returning
-                                (the reply's contents will be returned)
-    \value NoUseEventLoop       don't use an event loop to wait for a reply, but instead block on
-                                network operations while waiting. This option means the
-                                user-interface may not be updated for the duration of the call.
-    \value UseEventLoop         use the Qt event loop to wait for a reply. This option means the
-                                user-interface will update, but it also means other events may
-                                happen, like signal delivery and other D-Bus method calls.
-
-    When using UseEventLoop, applications must be prepared for reentrancy in any function.

-    \page StandardInterfaces Standard D-Bus Interfaces
-
-    The standard, well-known interfaces provided by D-Bus are as follows:
-    \value org.freedesktop.DBus.Peer            Peer detection
-    \value org.freedesktop.DBus.Introspectable  Introspection of remote object's contents
-    \value org.freedesktop.DBus.Properties      Access to remote object's properties
-
-    The QtDBus implementation provides easy access to those three interfaces with the
-    QDBusPeerInterface, QDBusIntrospectableInterface and QDBusPropertiesInterface classes. As a
-    convenience form, they can also be accessed by the classes org::freedesktop::DBus::Peer,
-    org::freedesktop::DBus::Introspectable and org::freedesktop::DBus::Properties.
-
-    Those three classes also illustrate code-generation by the \ref dbusidl2cpp tool: the methods
-    defined in those three interfaces are provided as member functions in the QtDBus classes, which
-    are capable of type-checking the parameters at compile-time, in order to guarantee that they
-    conform to the types expected by the remote objects.
