Detailed description

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.

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.

[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.

[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.

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.

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.

[event] void aboutToClose

Description: Signal declaration for QBuffer::aboutToClose()

You can bind a procedure to this signal.

[const] bool atEnd

Description: Method bool QBuffer::atEnd()

This is a reimplementation of QIODevice::atEnd

string buffer

Description: Method QByteArray &QBuffer::buffer()

[const] string buffer

Description: Method const QByteArray &QBuffer::buffer()

[event] void bytesWritten(long long bytes)

Description: Signal declaration for QBuffer::bytesWritten(qint64 bytes)

You can bind a procedure to this signal.

[const] bool canReadLine

Description: Method bool QBuffer::canReadLine()

This is a reimplementation of QIODevice::canReadLine

void close

Description: Method void QBuffer::close()

This is a reimplementation of QIODevice::close

void create

Description: Ensures the C++ object is created

Use of this method is deprecated. Use _create instead

[const] string data

Description: Method const QByteArray &QBuffer::data()

Python specific notes:

The object exposes a readable attribute 'data'. This is the getter.

void data=(string data)

Description: Method void QBuffer::setData(const QByteArray &data)

Python specific notes:

The object exposes a writable attribute 'data'. This is the setter.

void destroy

Description: Explicitly destroys the object

Use of this method is deprecated. Use _destroy instead

[event] void destroyed(QObject ptr arg1)

Description: Signal declaration for QBuffer::destroyed(QObject *)

You can bind a procedure to this signal.

[const] bool is_const_object?

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

Use of this method is deprecated. Use _is_const_object? instead

[static] new QBuffer new(QObject ptr parent = 0)

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

This method creates an object of class QBuffer.

Python specific notes:

This method is the default initializer of the object

[static] new QBuffer new(string ptr buf,QObject ptr parent = 0)

Description: Constructor QBuffer::QBuffer(QByteArray *buf, QObject *parent)

This method creates an object of class QBuffer.

Python specific notes:

This method is the default initializer of the object

bool open(const QIODevice_QFlags_OpenModeFlag openMode)

Description: Method bool QBuffer::open(QFlags<QIODevice::OpenModeFlag> openMode)

This is a reimplementation of QIODevice::open

[const] long long pos

Description: Method qint64 QBuffer::pos()

This is a reimplementation of QIODevice::pos

[event] void readChannelFinished

Description: Signal declaration for QBuffer::readChannelFinished()

You can bind a procedure to this signal.

[event] void readyRead

Description: Signal declaration for QBuffer::readyRead()

You can bind a procedure to this signal.

bool seek(long long off)

Description: Method bool QBuffer::seek(qint64 off)

This is a reimplementation of QIODevice::seek

void setBuffer(string ptr a)

Description: Method void QBuffer::setBuffer(QByteArray *a)

void setData(string data)

Description: Method void QBuffer::setData(const QByteArray &data)

Python specific notes:

void setData(string data,int len)

Description: Method void QBuffer::setData(const char *data, int len)

[const] long long size

Description: Method qint64 QBuffer::size()

This is a reimplementation of QIODevice::size

Python specific notes:

This method is also available as 'len(object)'
