The QAbstractTextDocumentLayout class is an abstract base class used to implement custom layouts for QTextDocuments.
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 setDocumentLayout() function.
You can insert custom objects into a QTextDocument; see the QTextObjectInterface class description for details.
See also QTextObjectInterface.
|
protected |
| QtGui.QAbstractTextDocumentLayout.QAbstractTextDocumentLayout | ( | QTextDocument | doc | ) |
Creates a new text document layout for the given document.
| new string QtGui.QAbstractTextDocumentLayout.AnchorAt | ( | QPointF | pos | ) |
Returns the reference of the anchor the given position, or an empty string if no anchor exists at that point.
|
pure virtual |
Returns the bounding rectangle of block.
Implemented in QtGui.QPlainTextDocumentLayout.
|

Reimplemented from QtCore.QObject.
Reimplemented in QtGui.QPlainTextDocumentLayout.
| new void QtGui.QAbstractTextDocumentLayout.Dispose | ( | ) |
| new QTextDocument QtGui.QAbstractTextDocumentLayout.Document | ( | ) |
Returns the text document that this layout is operating on.
|
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.
See also QTextLayout.
Implemented in QtGui.QPlainTextDocumentLayout.
|
pure virtual |
Returns the total size of the document's layout.
This information can be used by display widgets to update their scroll bars correctly.
See also documentSizeChanged() and QTextDocument::pageSize.
Implemented in QtGui.QPlainTextDocumentLayout.
|
pure virtual |
Draws the layout with the given painter using the given context.
Implemented in QtGui.QPlainTextDocumentLayout.
|
protectedvirtual |
This function is called to draw the inline object, object, with the given painter within the rectangle specified by rect using the specified text format.
posInDocument specifies the position of the object within the document.
The default implementation calls drawObject() on the object handlers. This function is called only within Qt. Subclasses can reimplement this function to customize the drawing of inline objects.
See also draw().
|
protected |
Returns the character format that is applicable at the given position.
|
protected |
|
pure virtual |
Returns the bounding rectangle of frame.
Implemented in QtGui.QPlainTextDocumentLayout.
| new QTextObjectInterface QtGui.QAbstractTextDocumentLayout.HandlerForObject | ( | int | objectType | ) |
Returns a handler for objects of the given objectType.
|
pure virtual |
Returns the cursor postion for the given point with the specified accuracy. Returns -1 if no valid cursor position was found.
Implemented in QtGui.QPlainTextDocumentLayout.
|
protected |
This signal is emitted when the size of the document layout changes to newSize.
Subclasses of QAbstractTextDocumentLayout should emit this signal when the document's entire layout size changes. This signal is useful for widgets that display text documents since it enables them to update their scroll bars correctly.
See also documentSize().
|
protected |
This signal is emitted when the number of pages in the layout changes; newPages is the updated page count.
Subclasses of QAbstractTextDocumentLayout should emit this signal when the number of pages in the layout has changed. Changes to the page count are caused by changes to the layout or the document content itself.
See also pageCount().
|
protected |
This signal is emitted when the rectangle rect has been updated.
Subclasses of QAbstractTextDocumentLayout should emit this signal when the layout of the contents change in order to repaint.
|
protected |
This signal is emitted when the rectangle rect has been updated.
Subclasses of QAbstractTextDocumentLayout should emit this signal when the layout of the contents change in order to repaint.

This signal is emitted when the specified block has been updated.
Subclasses of QAbstractTextDocumentLayout should emit this signal when the layout of block has changed in order to repaint.
This function was introduced in Qt 4.4.
|
pure virtual |
Returns the number of pages contained in the layout.
See also pageCountChanged().
Implemented in QtGui.QPlainTextDocumentLayout.
|
protectedvirtual |
Lays out the inline object item using the given text format.
posInDocument specifies the position of the object within the document.
The default implementation does nothing. This function is called only within Qt. Subclasses can reimplement this function to customize the position of inline objects.
See also drawInlineObject().
| new void QtGui.QAbstractTextDocumentLayout.RegisterHandler | ( | int | objectType, |
| QObject | component | ||
| ) |
Registers the given component as a handler for items of the given objectType.
Note: registerHandler() has to be called once for each object type. This means that there is only one handler for multiple replacement characters of the same object type.
|
protectedvirtual |
Sets the size of the inline object item corresponding to the text format.
posInDocument specifies the position of the object within the document.
The default implementation resizes the item to the size returned by the object handler's intrinsicSize() function. This function is called only within Qt. Subclasses can reimplement this function to customize the resizing of inline objects.
