How to save file as ".pdf" from QPrinter

[nifei]

Hi, all,
I want to save file as "outpuf.pdf" that is previewed via QPrintPreviewWidget. according to Qt's assistant, void QPrinter::setOutputToFile ( bool enable ) can be used, however, when i called this function, error C2039: 'setOutputToFile' : is not a member of 'QPrinter' occurs.

Why?

You should use

yourPrinter.setOutputFormat (QPrinter::PdfFormat);

yourPrinter.setOutputFormat (QPrinter::PdfFormat);

To copy to clipboard, switch view to plain text mode

'setOutputToFile' is a member of of the Qt 3 support layer. You should use following:

printer.setOutputFormat(QPrinter::PdfFormat);

I supposed that "out.pdf" will be created automatically when the slot print(QPrinter*) is invoked by QPrintPreviewWidget:aintRequested(QPrinter*), but i was wrong. I just called print(QPrinter*) and the file is created.
