QTextObject ¶

概要 ¶

详细描述 ¶

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 createObject() which acts as a factory method for creating text objects.
