Bind Timer with a bool variable.

Hi, i stuck again. I am trying to show my label after 5 clicks on my Pushbutton else label should hide. How can i count 1 click after 1 click? My problem is the loop i have only managed to get 5 counts with no click. I need 1 count with 1 click on the button. I tried to put QObject::connect(but, &Button::clicked, but,&Button::count); in my loop instead of "but->count" but it does not work. Do i need a mousepressevent here?

void Button::count()              //thats my method i have connected with my Button
{
    counter++;
     qDebug()<<counter;
}


QObject::connect(but, &Button::clicked, but,&Button::count);    //Connection



    while (but->counter!=5)   //my loop
    {
        if(but->counter==5)
        {
            labb->show();
        }
        else
        {
           but->count();    //here i want to click and count
        }
    }

The while loop blocks your counting on click. You dont need it.

Add something like

QObject::connect(but, &Button::clicked, this ,&MainWindow::onCount);


MainWindow::onCount{
if(but->counter==5)
        {
            labb->show();
        }

}

Hey. I how can i make that label to show my counter?

void mainWin::onCount()
{
    if(counter==4)
    {
        labb->show();
        labb->setText("Hello World");
    }


    counter++;
    
    qDebug()<<counter;    //i want that counter to be shown with that label2
    
    label2->setText(counter);  //i want that label to show my  counter



}

//i want that label to show my counter

Then convert it to a string first using https://doc.qt.io/qt-6/qstring.html#number ...

As you learn you need to read the documentation for yourself, not ask at every stage. QLabel::setText() accepts a QString as its argument. You have a number in counter. So look through/search the QString Class documentation page for a suitable method to convert a number to string....

EDIT
It seems @jsulm has already given this away. Shame! :( It's better you learn how to do programming than just ask and be told....

@JonB Agree. I really wonder why so many people ask questions which can be easily answered by simply looking at documentation...

Hi guys. I dont understand why the button is sometimes not clickable while moving. So i am starting the Timer with one button click and after that the button is moving but sometime its unclickable.

void mainWindow::timerStart()   //timer is starting
{
    if(counter==0)
    {
        sTimer->start(1000);

void MainWindow::buttonMove()  //Pushbutton random position
{
    int x = rand() % 230;
    int y = rand() % 245;
    but->setGeometry(x, y, 50, 70);
}

QObject::connect(buttton,&Button::clicked,this,&MainWindow::timerStart);  //starts the timer


QObject::connect(sTimer,&timer::timeout,this,&MainWindow::buttonMove); //every second the button is moving but i cant always click it because its unclickable i dont understand why? its a Pushbutton

@thomasGl Not possible to say with the code you posted. You can create a minimal compilable application which shows this issue and share it, so others can take a look.

thomasGl

how can i do that?

jsulm

@thomasGl What exactly?

thomasGl

creating a minimal compilable application and post it. Do you mean my full code?

thomasGl

Ok my fault it works now. I need make more timer in my code.

No, just a MINIMAL compilable application which shows the problem...
