qt's private headers and classes

Hello
I am implementing a class to output the contents of a QTextDocument in a custom format.
I started to look at the code that outputs in odf format and this code makes use of the QTextDocumentPrivate class defined in Qt\4.7.4\src\gui\text\qtextdocument_p.h

My question is – can I follow this lead and use these ‘private’ classes?

Thanks

No, you can't use private headers. At least not in any easy way.
