QTextDocumentWriter Class

Member Function Documentation

QTextDocumentWriter::QTextDocumentWriter()

Constructs an empty QTextDocumentWriter object. Before writing, you must call setFormat() to set a document format, then setDevice() or setFileName().

QTextDocumentWriter::QTextDocumentWriter(QIODevice *device, const QByteArray &format)

Constructs a QTextDocumentWriter object to write to the given device in the document format specified by format.

QTextDocumentWriter::QTextDocumentWriter(const QString &fileName, const QByteArray &format = QByteArray())

Constructs an QTextDocumentWriter object that will write to a file with the name fileName, using the document format specified by format. If format is not provided, QTextDocumentWriter will detect the document format by inspecting the extension of fileName.

QTextDocumentWriter::~QTextDocumentWriter()

Destroys the QTextDocumentWriter object.

QTextCodec *QTextDocumentWriter::codec() const

Returns the codec that is currently assigned to the writer.

See also setCodec().

QIODevice *QTextDocumentWriter::device() const

Returns the device currently assigned, or 0 if no device has been assigned.

See also setDevice().

QString QTextDocumentWriter::fileName() const

If the currently assigned device is a QFile, or if setFileName() has been called, this function returns the name of the file to be written to. In all other cases, it returns an empty string.

See also setFileName() and setDevice().

QByteArray QTextDocumentWriter::format() const

Returns the format used for writing documents.

See also setFormat().

void QTextDocumentWriter::setCodec(QTextCodec *codec)

Sets the codec for this stream to codec. The codec is used for encoding any data that is written. By default, QTextDocumentWriter uses UTF-8.

See also codec().

void QTextDocumentWriter::setDevice(QIODevice *device)

Sets the writer's device to the device specified. If a device has already been set, the old device is removed but otherwise left unchanged.

If the device is not already open, QTextDocumentWriter will attempt to open the device in QIODevice::WriteOnly mode by calling open().

Note: This will not work for certain devices, such as QProcess, QTcpSocket and QUdpSocket, where some configuration is required before the device can be opened.

See also device() and setFileName().

void QTextDocumentWriter::setFileName(const QString &fileName)

Sets the name of the file to be written to fileName. Internally, QTextDocumentWriter will create a QFile and open it in QIODevice::WriteOnly mode, and use this file when writing the document.

See also fileName() and setDevice().

void QTextDocumentWriter::setFormat(const QByteArray &format)

Sets the format used to write documents to the format specified. format is a case insensitive text string. For example:

        QTextDocumentWriter writer;
        writer.setFormat("odf"); // same as writer.setFormat("ODF");

You can call supportedDocumentFormats() for the full list of formats QTextDocumentWriter supports.

See also format().

[static] QList<QByteArray> QTextDocumentWriter::supportedDocumentFormats()

Returns the list of document formats supported by QTextDocumentWriter.

By default, Qt can write the following formats:

See also setFormat().

bool QTextDocumentWriter::write(const QTextDocument *document)

Writes the given document to the assigned device or file and returns true if successful; otherwise returns false.

bool QTextDocumentWriter::write(const QTextDocumentFragment &fragment)

Writes the document fragment specified by fragment to the assigned device or file and returns true if successful; otherwise returns false.
