QPainterPath::Element class specifies the position and type of a subpath

QPixmapCache::Key class can be used for efficient access to the QPixmapCache

This class is used in conjunction with the QPainter::drawPixmapFragments() function to specify how a pixmap, or sub-rect of a pixmap, is drawn

Abstract base class used to implement custom layouts for QTextDocuments

Implements support for objects with editable text

Defines an interface that exposes information about accessible objects

Notfies the accessibility framework that the state of an object has changed

Signifies a change in a table, list, or tree where cells are added or removed. If the change affected a number of rows, firstColumn and lastColumn will return -1. Likewise for columns, the row functions may return -1
