Compiler error for accept and ignore calls when processing a close event

[Guerrian]

void MainWindow::closeEvent(QCloseEvent *event)
{
    if (checkSave())
    {
        saveSettings();
        event->accept();
    }
    else
        event->ignore();
}

Gives error: member access into incomplete type 'QCloseEvent' on both lines with "event->".
