Detailed Description#

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

The class is used to send arguments over D-Bus to remote applications and to receive them back. D-Bus offers an extensible type system, based on a few primitive types and associations of them. See the Qt D-Bus Type System page for more information on the type system.

QDBusArgument is the central class in the Qt D-Bus type system, providing functions to marshall and demarshall the primitive types. The compound types are then created by association of one or more of the primitive types in arrays, dictionaries or structures.

The following example illustrates how a structure containing an integer and a string can be constructed using the Qt D-Bus type system :

class MyStructure():

    count = int()
    name = QString()

    # ...

Q_DECLARE_METATYPE(MyStructure)
# Marshall the MyStructure data into a D-Bus argument
QDBusArgument operator<<(QDBusArgument argument, MyStructure myStruct)

    argument.beginStructure()
    argument << myStruct.count << myStruct.name
    argument.endStructure()
    return argument

# Retrieve the MyStructure data from the D-Bus argument
QDBusArgument operator>>(QDBusArgument argument, MyStructure myStruct)

    argument.beginStructure()
    argument >> myStruct.count >> myStruct.name
    argument.endStructure()
    return argument

The type has to be registered with qDBusRegisterMetaType() before it can be used with QDBusArgument . Therefore, somewhere in your program, you should add the following code:

qDBusRegisterMetaType<MyStructure>()

Once registered, a type can be used in outgoing method calls (placed with call() ), signal emissions from registered objects or in incoming calls from remote applications.

It is important to note that the operator<< and operator>> streaming functions must always produce the same number of entries in case of structures, both in reading and in writing (marshalling and demarshalling), otherwise calls and signals may start to silently fail.

The following example illustrates this wrong usage in context of a class that may contain invalid data:

//bad code
    // Wrongly marshall the MyTime data into a D-Bus argument
    QDBusArgument &operator<<(QDBusArgument &argument, const MyTime &mytime)
    {
        argument.beginStructure();
        if (mytime.isValid)
            argument << true << mytime.hour
                     << mytime.minute << mytime.second;
        else
            argument << false;
        argument.endStructure();
        return argument;
    }

In this example, both the operator<< and the operator>> functions may produce a different number of reads/writes. This can confuse the Qt D-Bus type system and should be avoided.

class PySide6.QtDBus.QDBusArgument#

PySide6.QtDBus.QDBusArgument(other)

Parameters:

otherPySide6.QtDBus.QDBusArgument

Constructs an empty QDBusArgument argument.

An empty QDBusArgument object does not allow either reading or writing to be performed.

Constructs a copy of the other QDBusArgument object.

Both objects will therefore contain the same state from this point forward. QDBusArguments are explicitly shared and, therefore, any modification to either copy will affect the other one too.

PySide6.QtDBus.QDBusArgument.ElementType#

This enum describes the type of element held by the argument.

Constant

Description

QDBusArgument.BasicType

A basic element, which is understood by QVariant. The following types are considered basic: bool, byte, short, ushort, int, uint, qint64, quint64, double, QString, QByteArray, QDBusObjectPath , QDBusSignature

QDBusArgument.VariantType

The variant element ( QDBusVariant )

QDBusArgument.ArrayType

An array element, usually represented by QList<T>. Note: QByteArray and associative maps are not considered arrays, even if the D-Bus protocol transports them as such.

QDBusArgument.StructureType

A custom type represented by a structure, like QDateTime, QPoint, etc.

QDBusArgument.MapType

An associative container, like QMap<Key, Value> or QHash<Key, Value>

QDBusArgument.MapEntryType

One entry in an associative container: both the key and the value form one map-entry type.

QDBusArgument.UnknownType

The type is unknown or we have reached the end of the list.

currentType()

PySide6.QtDBus.QDBusArgument.appendVariant(v)#
Parameters:

v – object

PySide6.QtDBus.QDBusArgument.asVariant()#
Return type:

object

Returns the current argument in the form of a QVariant. Basic types will be decoded and returned in the QVariant, but for complex types, this function will return a QDBusArgument object in the QVariant. It is the caller’s responsibility to decode the argument (for example, by calling asVariant() in it).

For example, if the current argument is an INT32, this function will return a QVariant with an argument of type QMetaType::Int. For an array of INT32, it will return a QVariant containing a QDBusArgument .

If an error occurs or if there are no more arguments to decode (i.e., we are at the end of the argument list), this function will return an invalid QVariant.

atEnd()

PySide6.QtDBus.QDBusArgument.atEnd()#
Return type:

bool

Returns true if there are no more elements to be extracted from this QDBusArgument . This function is usually used in QDBusArgument objects returned from beginMap() and beginArray() .

PySide6.QtDBus.QDBusArgument.beginArray()#

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

Recurses into the D-Bus array to allow extraction of the array elements.

This function is used usually in operator>> streaming operators, as in the following example:

# Extract a MyArray array of MyElement elements
QDBusArgument operator>>(QDBusArgument argument, MyArray myArray)

    argument.beginArray()
    myArray.clear()
    while not argument.atEnd():
        element = MyElement()
        argument >> element
        myArray.append(element)

    argument.endArray()
    return argument

If the type you want to demarshall is a QList or any of the Qt’s Container Classes that take one template parameter, you need not declare an operator>> function for it, since Qt D-Bus provides generic templates to do the job of demarshalling the data. The same applies for STL’s sequence containers, such as std::list, std::vector, etc.

PySide6.QtDBus.QDBusArgument.beginArray(elementMetaType)
Parameters:

elementMetaTypePySide6.QtCore.QMetaType

Warning

    argument.beginArray(qMetaTypeId<MyElement>())
    for element in myArray:
        argument << element
    argument.endArray()
    return argument

If the type you want to marshall is a QList or any of the Qt’s Container Classes that take one template parameter, you need not declare an operator<< function for it, since Qt D-Bus provides generic templates to do the job of marshalling the data.

    argument.beginArray(qMetaTypeId<MyElement>())
    for element in myArray:
        argument << element
    argument.endArray()
    return argument

If the type you want to marshall is a QList or any of the Qt’s Container Classes that take one template parameter, you need not declare an operator<< function for it, since Qt D-Bus provides generic templates to do the job of marshalling the data.

        argument >> key >> value
        argument.endMapEntry()
        myDict.insert(key, value)

    argument.endMap()
    return argument

If the type you want to demarshall is a QMap or QHash, you need not declare an operator>> function for it, since Qt D-Bus provides generic templates to do the job of demarshalling the data.

PySide6.QtDBus.QDBusArgument.beginMap(keyMetaType, valueMetaType)
Parameters:

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

Opens a new D-Bus map suitable for appending elements. Maps are containers that associate one entry (the key) to another (the value), such as Qt’s QMap or QHash. The ids of the map’s key and value meta types must be passed in keyMetaType and valueMetaType respectively.

This function is used usually in operator<< streaming operators, as in the following example:

# Append a dictionary that associates ints to MyValue types
QDBusArgument operator<<(QDBusArgument argument, MyDictionary myDict)

    argument.beginMap(QMetaType.fromType<int>(), QMetaType.fromType<MyValue>())

        argument << i.key() << i.value()
        argument.endMapEntry()
