No such slot

[ABZB]

I am obtaining the following error when I run this program:

"QObject::connect: No such slot MainWindow::read_deck(const QString &fileName) in ../Card_Probability_Calc/mainwindow.cpp:232
The program has unexpectedly finished."

void MainWindow::create_actions()

    //saveAction = new QAction(tr("Save results to file"), this);
   // QObject::connect(saveAction, SIGNAL(triggered()), this, SLOT(save_analysis()));
 
    analyzeAction = new QAction(tr("Perform deck analysis"), this);

I have already forced the _moc file to be redone.

Added after 28 minutes:

Additionally, all of the connects for the pushbuttons are also non-functional

[wysota]

Don't put variable names in connect() statements. Only types are allowed. Also think where should the value for a slot parameter come from if the signal it connects to doesn't carry any values.

[ABZB]

Ok, I changed the one function that required a parameter. I am still getting an error. non of my connections are connecting.

QObject::connect: No such signal QPushButton::QPushButton::clicked() in ../Card_Probability_Calc/mainwindow.cpp:245
QObject::connect: No such signal QPushButton::QPushButton::clicked() in ../Card_Probability_Calc/mainwindow.cpp:246
QObject::connect: No such signal QPushButton::QPushButton::clicked() in ../Card_Probability_Calc/mainwindow.cpp:248
QObject::connect: No such signal QPushButton::QPushButton::clicked() in ../Card_Probability_Calc/mainwindow.cpp:249
QObject::connect: No such signal QPushButton::QPushButton::clicked() in ../Card_Probability_Calc/mainwindow.cpp:251
QObject::connect: No such signal QPushButton::QPushButton::clicked() in ../Card_Probability_Calc/mainwindow.cpp:252

In lines with connect change QPushButton::clicked() to clicked().
