signal into loop

[elicat]

Greetings,
I have a method that, based on some conditions, executes a signal that changes the style of an object (in my case a paramquery grid row).
checking through console.log I noticed that the signals are executed in correct sequence but all together at the end of the method.
I thought that when it executes a signal it was executed instantly... where am I wrong?

EXAMPLE

for (int i = 0; i < arrayDataRowLauncher.size(); i++) {
   . . . .
    if (fileFinish.exists()) {
        rowStyle["background-color"] = "#98fb98";
        rowStyle["color"] = "#FFFFFF";  
        jsonObjectDataRowLauncher["pq_rowstyle"] = rowStyle;
    } else {
        rowStyle["background-color"] = "yellow";
        rowStyle["color"] = "black";  
        jsonObjectDataRowLauncher["pq_rowstyle"] = rowStyle;
    }
    emit elabSignal(jsonObjectDataRowLauncher);
}

Hi,

What is connect to that signal ?
How is it connected ?
Do they live in the same thread ?

@SGaist Hello,
Be patient and remember that I am self-taught and that I am only using qt/c++/qml/qwebengine in one project, therefore with little possibility of professional growth in this area.

The signal is connect into QWebChannel

window.onload = function () {
    new QWebChannel(qt.webChannelTransport, function (channel) {
         webobj = channel.objects.wiseMan;
    }
}

I couldn't figure out how to get a method or signal to run in a new threads.
I tried this way, where EngineIndexHtml is class which contains the declare of signal

EngineIndexHtml* workerEngineIndexHtml;
QThread workerThreadEngineIndexHtml;
workerThreadEngineIndexHtml.moveToThread(&workerThreadEngineIndexHtml);
connect(workerEngineIndexHtml, &EngineIndexHtml::elabSignal, this, &EngineIndexHtml::elabSignal);
// Starting the worker thread
workerThreadEngineIndexHtml.start();
emit elabSignal(jsonObjectDataRowLauncher);

But i have this wrong and I didn't know how to solve it, I probably misunderstood how to run a new thread
