Detailed Description
The QTextObject class is a base class for different kinds of objects that can group parts of a QTextDocument together.
The common grouping text objects are lists (QTextList), frames (QTextFrame), and tables (QTextTable). A text object has an associated format() and document().
There are essentially two kinds of text objects: those that are used with blocks (block formats), and those that are used with characters (character formats). The first kind are derived from QTextBlockGroup, and the second kind from QTextFrame.
You rarely need to use this class directly. When creating custom text objects, you will also need to reimplement QTextDocument::createObject() which acts as a factory method for creating text objects.
See also QTextDocument and Text Object Example.
