Thread problem

[plopes21]

Good morning people,

I'm with a problem threading.

I want to start multiple threads at program start and I am not getting.

In mainwindow.ccp have the following.

MainWindow.cpp

* The alarm;
a.run ();

* The alarm;
a.run ();

Class Alarm

class Alarm : public QThread
{  
    Q_OBJECT
public:
    Alarm(QObject* = 0);
void iniciarValoresAlarme();
void run();
 
signals:
    void itsTime();
 
};
#endif

class Alarm : public QThread
{  
    Q_OBJECT
public:
    Alarm(QObject* = 0);
void iniciarValoresAlarme();
void run();

signals:
    void itsTime();

};
#endif

Alarm.cpp

Alarm::Alarm(QObject* parent) :
    QThread(parent)
{}
 
void Alarm::run(){
  exec();
}
void Alarm::iniciarValoresAlarme()
{    
    QDateTime today = QDateTime::currentDateTime();
    year = today.date().year();
    month = today.date().month();
    day = today.date().day();
//    hours = 0;
//    minutes = 0;
    seconds = 0;
    timeToAlarm = 0;
 
 
    timer = new QTimer(this);
 
    connect(timer, SIGNAL(timeout()), this, SLOT(finalizarAlarm()));
    connect(this,SIGNAL(itsTime()),this,SLOT(launchAlarm()));
    iniciarAlarme();
    start();
    qDebug()<<"Depois do start antes do wait";
    wait();
 
}

Alarm::Alarm(QObject* parent) :
    QThread(parent)
{}

void Alarm::run(){
  exec();
}
void Alarm::iniciarValoresAlarme()
{    
    QDateTime today = QDateTime::currentDateTime();
    year = today.date().year();
    month = today.date().month();
    day = today.date().day();

    seconds = 0;
    timeToAlarm = 0;


    timer = new QTimer(this);

    connect(timer, SIGNAL(timeout()), this, SLOT(finalizarAlarm()));
    connect(this,SIGNAL(itsTime()),this,SLOT(launchAlarm()));
    iniciarAlarme();
    start();
    qDebug()<<"Depois do start antes do wait";
    wait();

}

this code don´t work.

What the problem?

1. Show us full method in MainWindow which creates this threads.
2. What is "this code don't work" ?

[plopes21]

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
 Alarm a;
a.run();
}

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
 Alarm a;
a.run();
}

The main window is not shown.

[Lesiok]

Lines 6 and 7 should be :

Alarm *a = new Alarm(this);
a->run();

Alarm *a = new Alarm(this);
a->run();

"The main window is not shown."

That is what show() is for.

QThread::run() does not start a new thread. QThread::start() does.

[plopes21]

Thanks my friends. Already works.

It took just put
Alarm *a = new Alarm(this);
a->run();

Still, you have no extra thread here.
