I have a working code , I believe the loop is similar to "foreach" syntax.
EDIT
I there a way to add counter / index INTO RANGE
foreach(...) loop ?

I know I can hack it by adding such variable inside the loop...

C++

<pre> 
const QStringList list { "SubWindow terminal    (QMdiArea )",
                            "SubWindow hcitool      (QMdiArea )",
                             "SubWindowbluetoothctl (QMdiArea )",
                             "SubWindow system      (QMdiArea )" };
    QAction *submenu_array[100];
    (int index = 0 ) _
    for ( const auto& i : list )
    {
        (index++_)
        qDebug() << i;

.....

Solution 1

You are free to replace the range based for loop with the standard for loop. See, for instance Container Classes - Iterating over Containers - index based in the QT documentation.

What you have coded is the C++ foreach which iterates a list.

Assuming I understand what you are asking ... if you want to do it by index then you can use the size() operator of the QList Class | Qt Core 6.6.1[^] to get the number of elements. something like:

C++

    for (int index = 0; index < list.size(); ++index)
    {
        qDebug() << list[index];
    }
// index will now be equal to list.size();
