Detailed Description

\inmodule QtDBus

Since: 4.2

The QDBusAbstractInterface class is the base class for all D-Bus interfaces in the Qt D-Bus binding, allowing access to remote interfaces.

Generated-code classes also derive from QDBusAbstractInterface, 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.

Here is the caller graph for this function:

◆ asyncCall() [2/2]

template<typename... Args>

template< typename...Args > QDBusPendingCall QDBusAbstractInterface::asyncCall	(	const QString &	method,
		Args &&...	args )

inline

Calls the method method on this interface and passes args to the method.

All args must be convertible to QVariant.

The parameters to call are passed on to the remote function via D-Bus as input arguments. The returned QDBusPendingCall object can be used to find out information about the reply.

It can be used the following way:

QDBusPendingCall pcall = interface->asyncCall("GetAPIVersion"_L1);
auto watcher = new QDBusPendingCallWatcher(pcall, this);
 
QObject::connect(watcher, &QDBusPendingCallWatcher::finished, this,
                 [&](QDBusPendingCallWatcher *w) {
    QString value = retrieveValue();
    QDBusPendingReply<int> reply(*w);
    QDBusPendingCall pcall;
    if (reply.argumentAt<0>() >= 14)
        pcall = interface->asyncCall("ProcessWorkUnicode"_L1, value);
    else
        pcall = interface->asyncCall("ProcessWork"_L1, "UTF-8"_L1, value.toUtf8());
 
    w = new QDBusPendingCallWatcher(pcall);
    QObject::connect(w,  &QDBusPendingCallWatcher::finished, this,
                     &Abstract_DBus_Interface::callFinishedSlot);
});

This example illustrates function calling with 0, 1 and 2 parameters and illustrates different parameter types passed in each (the first call to "ProcessWorkUnicode" will contain one Unicode string, the second call to "ProcessWork" will contain one string and one byte array). See call() for the same example in blocking (synchronous) calls.

Note: Before Qt 5.14, this function accepted a maximum of just eight (8) arguments.; Method calls to local {QDBusServer}'s are never asynchronous due to implementation limitations.

◆ asyncCallWithArgumentList()

QDBusPendingCall QDBusAbstractInterface::asyncCallWithArgumentList	(	const QString &	method,
		const QList< QVariant > &	args )

Since: 4.5 Places a call to the remote method specified by method on this interface, using args as arguments. This function returns a QDBusPendingCall object that can be used to track the status of the reply and access its contents once it has arrived.

Normally, you should place calls using asyncCall().

Note: Method calls to objects registered by the application itself are never asynchronous due to implementation limitations.

◆ call() [2/4]

template<typename... Args>

template< typename...Args > QDBusMessage QDBusAbstractInterface::call	(	const QString &	method,
		Args &&...	args )

inline

Calls the method method on this interface and passes args to the method.

All args must be convertible to QVariant.

The parameters to 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.

It can be used the following way:

QString value = retrieveValue();
QDBusMessage reply;
 
QDBusReply<int> api = interface->call("GetAPIVersion"_L1);
if (api >= 14)
  reply = interface->call("ProcessWorkUnicode"_L1, value);
else
  reply = interface->call("ProcessWork"_L1, "UTF-8"_L1, value.toUtf8());

This example illustrates function calling with 0, 1 and 2 parameters and illustrates different parameter types passed in each (the first call to "ProcessWorkUnicode" will contain one Unicode string, the second call to "ProcessWork" will contain one string and one byte array). See asyncCall() for the same example in non-blocking (asynchronous) calls.

Note: Before Qt 5.14, this function accepted a maximum of just eight (8) arguments.

template<typename... Args>

template< typename...Args > QDBusMessage QDBusAbstractInterface::call	(	QDBus::CallMode	mode,

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.Calls the method method on this interface and passes args to the method.

All args must be convertible to QVariant.

If mode is NoWaitForReply, then this function will return immediately after placing the call, without waiting for a reply from the remote method. Otherwise, mode indicates whether this function should activate the Qt Event Loop while waiting for the reply to arrive.

If this function reenters the Qt event loop in order to wait for the reply, it will exclude 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().

Note: Before Qt 5.14, this function accepted a maximum of just eight (8) arguments.

◆ callWithArgumentList()

QDBusMessage QDBusAbstractInterface::callWithArgumentList	(	QDBus::CallMode	mode,
		const QString &	method,
		const QList< QVariant > &	args )

Places a call to the remote method specified by method on this interface, using args as arguments.

This function returns the message that was received as a reply, which can be a normal QDBusMessage::ReplyMessage (indicating success) or QDBusMessage::ErrorMessage (if the call failed). The mode parameter specifies how this call should be placed.

If the call succeeds, lastError() will be cleared; otherwise, it will contain the error this call produced.

Normally, you should place calls using call().

Warning: If you use UseEventLoop, your code must be prepared to deal with any reentrancy: other method calls and signals may be delivered before this function returns, as well as other Qt queued signals and events.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.This function is deprecated.

Please use the overloaded version.

Places a call to the remote method specified by method on this interface, using args as arguments. This function returns immediately after queueing the call. The reply from the remote function or any errors emitted by it are delivered to the slot slot on object receiver.

This function returns true if the queueing succeeded: it does not indicate that the call succeeded. If it failed, the slot will be called with an error message. lastError() will not be set under those circumstances.

		const char *	errorMethod )

Places a call to the remote method specified by method on this interface, using args as arguments.

This function returns immediately after queueing the call. The reply from the remote function is delivered to the returnMethod on object receiver. If an error occurs, the errorMethod on object receiver is called instead.

This function returns true if the queueing succeeds. It does not indicate that the executed call succeeded. If it fails, the errorMethod is called. If the queueing failed, this function returns false and no slot will be called.

The returnMethod must have as its parameters the types returned by the function call. Optionally, it may have a QDBusMessage parameter as its last or only parameter. The errorMethod must have a QDBusError as its only parameter.

Note: Method calls to objects registered by the application itself are never asynchronous due to implementation limitations.
