Better implementation than function hopping (solved)

[houmingc]

Although the code below works. I have 60 function needs to run consecutively.
Anyone can provide a better solution, please

void mainWindow()
{          
           QTimer *timerForLED = new QTimer(this);
           connect(timerForLED,SIGNAL(timeout()),this,SLOT(nextSignalSlot1()));
           timerForLED->start(12000);
}

void MainWindow::nextSignalSlot1()
{
    TravelStatusChangedSlot(4,2,3,16);
    QTimer *timerForLED2 = new QTimer(this);
    connect(timerForLED2,SIGNAL(timeout()),this,SLOT(nextSignalSlot2()));
    timerForLED2->start(12000);
}

void MainWindow::nextSignalSlot2()
{
    TravelStatusChangedSlot(4,1,2,16);
    QTimer *timerForLED3 = new QTimer(this);
    connect(timerForLED3,SIGNAL(timeout()),this,SLOT(nextSignalSlot3()));
    timerForLED3->start(12000);
}

void MainWindow::nextSignalSlot3()
{
    TravelStatusChangedSlot(1,2,3,16);
    QTimer *timerForLED4 = new QTimer(this);
    connect(timerForLED4,SIGNAL(timeout()),this,SLOT(nextSignalSlot4()));
    timerForLED4->start(12000);

}

Wouldn't a for loop do it?
Or a non-singleshoot timer, that fires every x seconds?

Hi,

Isn't that just a variation of the question asked in this thread ?

In normal C we'd just put all the function pointers in an array and just iterate through the array.
Not sure if that is still easy to do in C++. Much like a state machine actually.

However, you can easily run the same function 60 times on a different instance. Much more object oriented than timerForLEDX type of static stuff.
Take a lookt at http://doc.qt.io/qt-5/qlist.html

QStateMachine Class may be the answer, also take a look at postDelayedEvent(QEvent * event, int delay)
