terminate a QThread from GUI

[OverTheOCean]

Hello guys,

I'm learning QThread with a simple application ... my thread start with a modified Run() function.

in the run(), l activate a QDialog, do some stuff and wait with exec() for the user to click on QPushbutton "Keep" or "close"

Thread_PulseMeas::Thread_PulseMeas(QObject *parent):
        QThread(parent)
{
    diag_RealTimePlot = new QDialog;
    ui_RealTimePlot.setupUi(diag_RealTimePlot);
    diag_RealTimePlot->setWindowFlags(Qt::FramelessWindowHint | Qt::WindowTitleHint | Qt::WindowMinimizeButtonHint | Qt::WindowMaximizeButtonHint);
    connect(ui_RealTimePlot.Close, SIGNAL(clicked()), this, SLOT(Close()));
    connect(ui_RealTimePlot.Add, SIGNAL(clicked()), this, SLOT(Add()));
};
 
void Thread_PulseMeas::run( Pulse_Meas *PulseMeas)
{
    diag_RealTimePlot->show();
    Pulse_measure(PulseMeas);
    exec();
 
}
 
void Thread_PulseMeas::Close()
{
    SetKeep(false);
    diag_RealTimePlot->close();
    exit();
}
void Thread_PulseMeas::Add()
{
    SetKeep(true);
    diag_RealTimePlot->close();
    exit();
}

Thread_PulseMeas::Thread_PulseMeas(QObject *parent):
        QThread(parent)
{
    diag_RealTimePlot = new QDialog;
    ui_RealTimePlot.setupUi(diag_RealTimePlot);
    diag_RealTimePlot->setWindowFlags(Qt::FramelessWindowHint | Qt::WindowTitleHint | Qt::WindowMinimizeButtonHint | Qt::WindowMaximizeButtonHint);
    connect(ui_RealTimePlot.Close, SIGNAL(clicked()), this, SLOT(Close()));
    connect(ui_RealTimePlot.Add, SIGNAL(clicked()), this, SLOT(Add()));
};

void Thread_PulseMeas::run( Pulse_Meas *PulseMeas)
{
    diag_RealTimePlot->show();
    Pulse_measure(PulseMeas);
    exec();

}

void Thread_PulseMeas::Close()
{
    SetKeep(false);
    diag_RealTimePlot->close();
    exit();
}
void Thread_PulseMeas::Add()
{
    SetKeep(true);
    diag_RealTimePlot->close();
    exit();
}

To copy to clipboard, switch view to plain text mode 

when l click "keep" or "close", the QDIALOG is closed but the thread is not terminated ....

am l missing something there ?

regards,

Michael
