    void MainWindow::on_actionPrint_triggered()
    {
    QPrinter *printer = new QPrinter(QPrinter::HighResolution);
    printer->setOutputFormat(QPrinter::PdfFormat);

    printer->setPaperSize(QPrinter::A4);
    printer->setOrientation(QPrinter::Landscape);
    printer->setFullPage(true);
    //printer->setResolution(100);
    printer->setOutputFileName("Desktop//aaaa.pdf");

    QPrintPreviewWidget *preview =0;
    preview = new QPrintPreviewWidget(printer,preview);

    preview->print();

    connect(preview, SIGNAL(paintRequested(QPrinter*)),allWorkspaceShapes[currentIndex]->drawShape,SLOT(Print(QPrinter*)));

    preview->show();

    }

    i used this and still didn't get anything, i have another problem in the code maybe?

    @rest said in print preview widget:
    That is NOT a valid path
    setOutputFileName("Desktop//aaaa.pdf");

    Please use a valid full path and only single /

    like
    C:/Users/SOMEUSERNAME/Desktop/test.pdf
