Detailed Description

QTextDocument is a container for structured rich text documents, providing support for styled text and various types of document elements, such as lists, tables, frames, and images. They can be created for use in a QTextEdit , or used independently.

Each document element is described by an associated format object. Each format object is treated as a unique object by QTextDocuments, and can be passed to objectForFormat() to obtain the document element that it is applied to.

A QTextDocument can be edited programmatically using a QTextCursor , and its contents can be examined by traversing the document structure. The entire document structure is stored as a hierarchy of document elements beneath the root frame, found with the rootFrame() function. Alternatively, if you just want to iterate over the textual contents of the document you can use begin() , end() , and findBlock() to retrieve text blocks that you can examine and iterate over.

The layout of a document is determined by the documentLayout() ; you can create your own QAbstractTextDocumentLayout subclass and set it using setDocumentLayout() if you want to use your own layout logic. The document’s title and other meta-information can be obtained by calling the metaInformation() function. For documents that are exposed to users through the QTextEdit class, the document title is also available via the documentTitle() function.

The toPlainText() and toHtml() convenience functions allow you to retrieve the contents of the document as plain text and HTML. The document’s text can be searched using the find() functions.

Undo/redo of operations performed on the document can be controlled using the setUndoRedoEnabled() function. The undo/redo system can be controlled by an editor widget through the undo() and redo() slots; the document also provides contentsChanged() , undoAvailable() , and redoAvailable() signals that inform connected editor widgets about the state of the undo/redo system. The following are the undo/redo operations of a QTextDocument :

  • Insertion or removal of characters. A sequence of insertions or removals within the same text block are regarded as a single undo/redo operation.

  • Insertion or removal of text blocks. Sequences of insertion or removals in a single operation (e.g., by selecting and then deleting text) are regarded as a single undo/redo operation.

  • Text character format changes.

  • Text block format changes.

  • Text block group format changes.

No resource is loaded, or the resource type is not known.

QTextDocument.HtmlResource

The resource contains HTML.

QTextDocument.ImageResource

The resource contains image data. Currently supported data types are Pixmap and Image . If the corresponding variant is of type ByteArray then Qt attempts to load the image using loadFromData . Icon is currently not supported. The icon needs to be converted to one of the supported types first, for example using pixmap .

QTextDocument.StyleSheetResource

This function is called by the rich text engine to request data that isn’t directly stored by QTextDocument , but still associated with it. For example, images are referenced indirectly by the name attribute of a QTextImageFormat object.

When called by Qt, type is one of the values of ResourceType .

If the QTextDocument is a child object of a QObject that has an invokable method such as QTextEdit , QTextBrowser or a QTextDocument itself then the default implementation tries to retrieve the data from the parent.

PySide2.QtGui.QTextDocument.markContentsDirty(from, length)

Replaces the entire contents of the document with the given Markdown-formatted text in the markdown string, with the given features supported. By default, all supported GitHub-style Markdown features are included; pass MarkdownDialectCommonMark for a more basic parse.

The Markdown formatting is respected as much as possible; for example, “*bold* text” will produce text where the first word has a font weight that gives it an emphasized appearance.

Parsing of HTML included in the markdown string is handled in the same way as in setHtml ; however, Markdown formatting inside HTML blocks is not supported.

Some features of the parser can be enabled or disabled via the features argument:

  • MarkdownNoHTML

  • Any HTML tags in the Markdown text will be discarded

The default is MarkdownDialectGitHub .

The undo/redo history is reset when this function is called.

PySide2.QtGui.QTextDocument.setPlainText(text)
Parameters

text – str

Replaces the entire contents of the document with the given plain text . The undo/redo history is reset when this function is called.

See also

setHtml()

PySide2.QtGui.QTextDocument.setTextWidth(width)
Parameters

width – float

The text width specifies the preferred width for text in the document. If the text (or content in general) is wider than the specified with it is broken into multiple lines and grows vertically. If the text cannot be broken into multiple lines to fit into the specified text width it will be larger and the size() and the idealWidth() property will reflect that.

If the text width is set to -1 then the text will not be broken into multiple lines unless it is enforced through an explicit line break or a new paragraph.

The default value is -1.

Setting the text width will also set the page height to -1, causing the document to grow or shrink vertically in a continuous way. If you want the document layout to break the text into multiple pages then you have to set the pageSize property instead.

PySide2.QtGui.QTextDocument.setUndoRedoEnabled(enable)
Parameters

enable – bool

This property holds whether undo/redo are enabled for this document.

This defaults to true. If disabled, the undo stack is cleared and no items will be added to it.

PySide2.QtGui.QTextDocument.setUseDesignMetrics(b)
Parameters

b – bool

This property holds whether the document uses design metrics of fonts to improve the accuracy of text layout.

If this property is set to true, the layout will use design metrics. Otherwise, the metrics of the paint device as set on setPaintDevice() will be used.

Using design metrics makes a layout have a width that is no longer dependent on hinting and pixel-rounding. This means that WYSIWYG text layout becomes possible because the width scales much more linearly based on paintdevice metrics than it would otherwise.

By default, this property is false .

PySide2.QtGui.QTextDocument.size()
Return type

PySide2.QtCore.QSizeF

Returns the actual size of the document. This is equivalent to documentLayout() ->documentSize();

The size of the document can be changed either by setting a text width or setting an entire page size.

Note that the width is always >= pageSize() . width() .

By default, for a newly-created, empty document, this property contains a configuration-dependent size.

PySide2.QtGui.QTextDocument.textWidth()
Return type

float

The text width specifies the preferred width for text in the document. If the text (or content in general) is wider than the specified with it is broken into multiple lines and grows vertically. If the text cannot be broken into multiple lines to fit into the specified text width it will be larger and the size() and the idealWidth() property will reflect that.

If the text width is set to -1 then the text will not be broken into multiple lines unless it is enforced through an explicit line break or a new paragraph.

The default value is -1.

Setting the text width will also set the page height to -1, causing the document to grow or shrink vertically in a continuous way. If you want the document layout to break the text into multiple pages then you have to set the pageSize property instead.

PySide2.QtGui.QTextDocument.toHtml([encoding=QByteArray()])
Parameters

encodingPySide2.QtCore.QByteArray

Return type

str

Returns a string containing an HTML representation of the document.

The encoding parameter specifies the value for the charset attribute in the html header. For example if ‘utf-8’ is specified then the beginning of the generated html will look like this:

<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"></head><body>...

If no encoding is specified then no such meta information is generated.

If you later on convert the returned html string into a byte array for transmission over a network or when saving to disk you should specify the encoding you’re going to use for the conversion to a byte array here.

PySide2.QtGui.QTextDocument.toMarkdown([features=QTextDocument.MarkdownDialectGitHub])
Parameters

featuresMarkdownFeatures

Return type

str

Returns a string containing a Markdown representation of the document with the given features , or an empty string if writing fails for any reason.

See also

setMarkdown

PySide2.QtGui.QTextDocument.toPlainText()
Return type

str

Returns the plain text contained in the document. If you want formatting information use a QTextCursor instead.

This function returns the same as toRawText() , but will replace some unicode characters with ASCII alternatives. In particular, no-break space (U+00A0) is replaced by a regular space (U+0020), and both paragraph (U+2029) and line (U+2028) separators are replaced by line feed (U+000A). If you need the precise contents of the document, use toRawText() instead.

Note

Embedded objects, such as images, are represented by a Unicode value U+FFFC (OBJECT REPLACEMENT CHARACTER).

See also

toHtml()

PySide2.QtGui.QTextDocument.toRawText()
Return type

str

Returns the raw text contained in the document without any formatting information. If you want formatting information use a QTextCursor instead.

PySide2.QtGui.QTextDocument.undo()

This is an overloaded function.

PySide2.QtGui.QTextDocument.undo(cursor)
Parameters

cursorPySide2.QtGui.QTextCursor

Undoes the last editing operation on the document if undo is available. The provided cursor is positioned at the end of the location where the edition operation was undone.

See the Qt Undo Framework documentation for details.

PySide2.QtGui.QTextDocument.undoAvailable(arg__1)
Parameters

arg__1 – bool

PySide2.QtGui.QTextDocument.undoCommandAdded()
PySide2.QtGui.QTextDocument.useDesignMetrics()
Return type

bool

This property holds whether the document uses design metrics of fonts to improve the accuracy of text layout.

If this property is set to true, the layout will use design metrics. Otherwise, the metrics of the paint device as set on setPaintDevice() will be used.

Using design metrics makes a layout have a width that is no longer dependent on hinting and pixel-rounding. This means that WYSIWYG text layout becomes possible because the width scales much more linearly based on paintdevice metrics than it would otherwise.

By default, this property is false .
