Detailed Description

The QAbstractTextDocumentLayout class is an abstract base class used to implement custom layouts for QTextDocuments.

Note

This class or function is reentrant.

The standard layout provided by Qt can handle simple word processing including inline images, lists and tables.

Some applications, e.g., a word processor or a DTP application might need more features than the ones provided by Qt's layout engine, in which case you can subclass QAbstractTextDocumentLayout to provide custom layout behavior for your text documents.

An instance of the QAbstractTextDocumentLayout subclass can be installed on a QTextDocument object with the QTextDocument::setDocumentLayout() function.

You can insert custom objects into a QTextDocument; see the QTextObjectInterface class description for details.

blockBoundingRect()

pure virtual

Returns the bounding rectangle of block.

Implemented in QPlainTextDocumentLayout, and QTextDocumentLayout.

Referenced by QTextCursorPrivate::blockLayout(), and QAccessibleTextEdit::rect().

document()

QTextDocument * QAbstractTextDocumentLayout::document

(

)

const

Returns the text document that this layout is operating on.

Referenced by QPlainTextDocumentLayout::blockBoundingRect(), QTextEngine::docLayout(), QTextDocumentLayout::documentChanged(), QPlainTextDocumentLayout::documentChanged(), QPlainTextDocumentLayout::documentSize(), drawInlineObject(), QPlainTextDocumentLayout::layoutBlock(), QPlainTextDocumentLayout::requestUpdate(), and resizeInlineObject().

{
    Q_D(const QAbstractTextDocumentLayout);
    return d->document;
}

documentChanged()

void QAbstractTextDocumentLayout::documentChanged ( int  position, int  charsRemoved, int  charsAdded  )

protectedpure virtual

This function is called whenever the contents of the document change.

A change occurs when text is inserted, removed, or a combination of these two. The change is specified by position, charsRemoved, and charsAdded corresponding to the starting character position of the change, the number of characters removed from the document, and the number of characters added.

For example, when inserting the text "Hello" into an empty document, charsRemoved would be 0 and charsAdded would be 5 (the length of the string).

Replacing text is a combination of removing and inserting. For example, if the text "Hello" gets replaced by "Hi", charsRemoved would be 5 and charsAdded would be 2.

For subclasses of QAbstractTextDocumentLayout, this is the central function where a large portion of the work to lay out and position document contents is done.

For example, in a subclass that only arranges blocks of text, an implementation of this function would have to do the following:

• Determine the list of changed QTextBlock(s) using the parameters provided.
• Each QTextBlock object's corresponding QTextLayout object needs to be processed. You can access the QTextBlock's layout using the QTextBlock::layout() function. This processing should take the document's page size into consideration.
• If the total number of pages changed, the pageCountChanged() signal should be emitted.
• If the total size changed, the documentSizeChanged() signal should be emitted.
• The update() signal should be emitted to schedule a repaint of areas in the layout that require repainting.

documentSize()

QSizeF QAbstractTextDocumentLayout::documentSize ( ) const
