In the following example in http://doc.qt.nokia.com/latest/gettingstartedqt.html:

Notepad::Notepad()
{
saveAction = new QAction(tr("&Open"), this);
saveAction = new QAction(tr("&Save"), this);
exitAction = new QAction(tr("E&xit"), this);

connect(openAction, SIGNAL(triggered()), this, SLOT(open()));
connect(saveAction, SIGNAL(triggered()), this, SLOT(save()));
connect(exitAction, SIGNAL(triggered()), qApp, SLOT(quit()));

fileMenu = menuBar()->addMenu(tr("&File"));
fileMenu->addAction(openAction);
fileMenu->addAction(saveAction);
fileMenu->addSeparator();
fileMenu->addAction(exitAction);

textEdit = new QTextEdit;
setCentralWidget(textEdit);

setWindowTitle(tr("Notepad"));
}

I think the "saveAction = new QAction(tr("&Open"), this);" should be "openAction"
