Detailed description

_create

Signature: void _create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

_destroy

Signature: void _destroy

Description: Explicitly destroys the object

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

_destroyed?

Signature: [const] bool _destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

_is_const_object?

Signature: [const] bool _is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

_manage

Signature: void _manage

Description: Marks the object as managed by the script side.

After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required.

Usually it's not required to call this method. It has been introduced in version 0.24.

_unmanage

Signature: void _unmanage

Description: Marks the object as no longer owned by the script side.

Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur.

Usually it's not required to call this method. It has been introduced in version 0.24.

asConstQAudioSystemFactoryInterface

Signature: [const] const QAudioSystemFactoryInterface ptr asConstQAudioSystemFactoryInterface

Description: Delivers the base class interface QAudioSystemFactoryInterface of QAudioSystemPlugin

Class QAudioSystemPlugin is derived from multiple base classes. This method delivers the QAudioSystemFactoryInterface base class aspect.

Use this version if you have a const reference.

asConstQObject

Signature: [const] const QObject ptr asConstQObject

Description: Delivers the base class interface QObject of QAudioSystemPlugin

Class QAudioSystemPlugin is derived from multiple base classes. This method delivers the QObject base class aspect.

Use this version if you have a const reference.

asQAudioSystemFactoryInterface

Signature: QAudioSystemFactoryInterface ptr asQAudioSystemFactoryInterface

Description: Delivers the base class interface QAudioSystemFactoryInterface of QAudioSystemPlugin

Class QAudioSystemPlugin is derived from multiple base classes. This method delivers the QAudioSystemFactoryInterface base class aspect.

asQObject

Signature: QObject ptr asQObject

Description: Delivers the base class interface QObject of QAudioSystemPlugin

Class QAudioSystemPlugin is derived from multiple base classes. This method delivers the QObject base class aspect.

availableDevices

Signature: [const] bytes[] availableDevices (const QAudio_Mode arg1)

Description: Virtual method QList<QByteArray> QAudioSystemPlugin::availableDevices(QAudio::Mode)

This method can be reimplemented in a derived class.

childEvent

Signature: void childEvent (QChildEvent ptr event)

Description: Virtual method void QAudioSystemPlugin::childEvent(QChildEvent *event)

This method can be reimplemented in a derived class.

createDeviceInfo

Signature: QAbstractAudioDeviceInfo ptr createDeviceInfo (bytes device, const QAudio_Mode mode)

Description: Virtual method QAbstractAudioDeviceInfo *QAudioSystemPlugin::createDeviceInfo(const QByteArray &device, QAudio::Mode mode)

This method can be reimplemented in a derived class.

createInput

Description: Virtual method bool QAudioSystemPlugin::event(QEvent *event)

This method can be reimplemented in a derived class.

eventFilter

Signature: bool eventFilter (QObject ptr watched, QEvent ptr event)

Description: Virtual method bool QAudioSystemPlugin::eventFilter(QObject *watched, QEvent *event)

Description: Constructor QAudioSystemPlugin::QAudioSystemPlugin(QObject *parent)

This method creates an object of class QAudioSystemPlugin.

Python specific notes:
This method is the default initializer of the object.

objectNameChanged

Signature: [signal] void objectNameChanged (string objectName)

Description: Signal declaration for QAudioSystemPlugin::objectNameChanged(const QString &objectName)

You can bind a procedure to this signal.

Python specific notes:
The object exposes a readable attribute 'objectNameChanged'. This is the getter.
The object exposes a writable attribute 'objectNameChanged'. This is the setter.
