How to print using qwebview using qt

When accessing the link from a browser, there is a print button and when you click it the function print will show. And I cannot do this on my program having a qwebview. Im using qt4.7.3 on Ubuntu 11.04.

QWebView has a void print(QPrinter * printer) const method. To show the print dialog, you'd use the QPrintDialog class.

You need to connect a QAction or some other signal to a slot that shows the print dialog, and another slot to the dialog's accepted signal.

class MyWindow : public QWidget {
    Q_OBJECT
    QWebView * m_webView;
    QScopedPointer<QPrinter> m_printer;
    ...
    Q_SLOT void showPrintDialog() {
        if (!m_printer) m_printer.reset(new QPrinter);
        QScopedPointer<QPrintDialog> dialog(new QPrintDialog(m_printer.data(), this));
        dialog->setAttribute(Qt::WA_DeleteOnClose);
        connect(dialog.data(), SIGNAL(accepted(QPrinter*)), SLOT(print(QPrinter*)));
        dialog->show();
        dialog.take(); // The dialog will self-delete
    }
    Q_SLOT void print(QPrinter* printer) {
        m_webView->print(printer);
    }
};
