Detailed Description

QTextBlockUserData provides an abstract interface for container classes that are used to associate application-specific user data with text blocks in a QTextDocument.

Generally, subclasses of this class provide functions to allow data to be stored and retrieved, and instances are attached to blocks of text using QTextBlock::setUserData(). This makes it possible to store additional data per text block in a way that can be retrieved safely by the application.

Each subclass should provide a reimplementation of the destructor to ensure that any private data is automatically cleaned up when user data objects are deleted.
