QTextInlineObject ¶

概要 ¶

详细描述 ¶

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() ，和 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() .
