Synopsis

Functions

Static functions

Detailed Description

To write a document, construct a QTextDocumentWriter object with either a file name or a device object, and specify the document format to be written. You can construct a writer and set the format using setFormat() later.

Call write() to write the document to the device. If the document is successfully written, this function returns true . However, if an error occurs when writing the document, it will return false.

Call supportedDocumentFormats() for a list of formats that QTextDocumentWriter can write.

Since the capabilities of the supported output formats vary considerably, the writer simply outputs the appropriate subset of objects for each format. This typically includes the formatted text and images contained in a document.

class PySide2.QtGui.QTextDocumentWriter

PySide2.QtGui.QTextDocumentWriter(device, format)

PySide2.QtGui.QTextDocumentWriter(fileName[, format=QByteArray()])

param format

PySide2.QtCore.QByteArray

param device

PySide2.QtCore.QIODevice

param fileName

str

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

PySide2.QtGui.QTextDocumentWriter.codec()
Return type

PySide2.QtCore.QTextCodec

Returns the codec that is currently assigned to the writer.

setCodec()

PySide2.QtGui.QTextDocumentWriter.device()
Return type

PySide2.QtCore.QIODevice

Returns the device currently assigned, or None if no device has been assigned.

See also

setDevice()

PySide2.QtGui.QTextDocumentWriter.fileName()
Return type

str

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.

PySide2.QtGui.QTextDocumentWriter.format()
Return type

PySide2.QtCore.QByteArray

Returns the format used for writing documents.

setFormat()

PySide2.QtGui.QTextDocumentWriter.setCodec(codec)
Parameters

codecPySide2.QtCore.QTextCodec

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.

codec()

PySide2.QtGui.QTextDocumentWriter.setDevice(device)
Parameters

devicePySide2.QtCore.QIODevice

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 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.

PySide2.QtGui.QTextDocumentWriter.setFileName(fileName)
Parameters

fileName – str

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

PySide2.QtGui.QTextDocumentWriter.setFormat(format)
Parameters

formatPySide2.QtCore.QByteArray

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.
