Detailed Description

\reentrant

The QTextInlineObject class represents an inline object in a QAbstractTextDocumentLayout and its implementations. \inmodule QtGui

Normally, you do not need to create a QTextInlineObject. It is used by QAbstractTextDocumentLayout to handle inline objects when implementing a custom layout.

The inline object has various attributes that can be set, for example using, setWidth(), setAscent(), and setDescent(). The rectangle it occupies is given by rect(), and its direction by textDirection(). Its position in the text layout is given by textPosition(), and its format is given by format().
