Rich Text Processing

The Scribe framework provides a set of classes for reading and manipulating structured rich text documents. Unlike previous rich text support in Qt, the new classes are centered around the QTextDocument class rather than raw textual information. This enables the developer to create and modify structured rich text documents without having to prepare content in an intermediate markup format.

The information within a document can be accessed via two complementary interfaces: A cursor-based interface is used for editing, and a read-only hierarchical interface provides a high level overview of the document structure. The main advantage of the cursor-based interface is that the text can be edited using operations that mimic a user's interaction with an editor, without losing the underlying structure of the document. The read-only hierarchical interface is most useful when performing operations such as searching and document export.
