QTextBlockUserData Class ReferenceThe QTextBlockUserData class is used to associate custom data with blocks of text. More... #include <QTextBlockUserData>Note: All functions in this class are reentrant. This class was introduced in Qt 4.1. Public Functions
Detailed DescriptionThe QTextBlockUserData class is used to associate custom data with blocks of text. 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.
