void QtGui.IQAbstractTextDocumentLayoutSignals.DocumentSizeChanged

(

QSizeF

newSize

)

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().

void QtGui.IQAbstractTextDocumentLayoutSignals.PageCountChanged

(

int

newPages

)

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().

void QtGui.IQAbstractTextDocumentLayoutSignals.Update

(

QRectF

arg1

)

void QtGui.IQAbstractTextDocumentLayoutSignals.Update

(

)

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.

void QtGui.IQAbstractTextDocumentLayoutSignals.UpdateBlock

(

QTextBlock

block

)

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.
