how to generate a PDF file with qt?

[toutarrive]

You have to use the QPrinter class to generate a pdf:

Qprinter printer;
printer.setOutputFileName(filename);
printer.setOutputFormat(QPrinter::PdfFormat);

Qprinter printer;
printer.setOutputFileName(filename);
printer.setOutputFormat(QPrinter::PdfFormat);

To copy to clipboard, switch view to plain text mode 

Have a look at void TextEdit::filePrintPdf() in http://doc.trolltech.com/4.2/demos-t...tedit-cpp.html .

Concerning viewing of a pdf doc, Qt is not shipped with a viewer, so you might have to use a third parties library or embed adobe ActiveX control in your app.
