    @mrjj Hi,
    If I store them in a list I think I won't get the output as key-value pair right?

    Hi
    Not if you only store a string but you could easily just do
    QVector<QPair<QString, QString>> list;
    or a similar structure to store both key and value in the same list.

        @mrjj Hi
        Okay, Got it Thank you.
        I have a doubt. In the container, the values can be stored in any order or if they are not in the order as .ini file will that be any problem later?

          Hi
          They will be stored in same order as you add them so if you add them in the order you read them it should be as you want. (same order as in ini file)

            The ini file/QSettings does not care about the order of entries. Only you seem to want this:

            My Requirement is to get in the order the same as my .ini file.

            Why do you even need this?

                It helps if you use code tags for posting this here.

                values.insert(childKey, settings.value(childKey).toString());

                Don't you mean:

                QVector<QPair<QString, QString>> values;
                ...
                values.insert(i, QPair<QString, QString>(childKey, settings.value(childKey).toString()));
                

                ?

                Define yourself a type for QPair<QString, QString> and this will read easier.

                  Hi,

                  Since you really want a specific order, wouldn't it be simpler to sort your container after loading it with data ? That way you would be a bit less depending on the storage format.

                    Hi
                    He wants same order as in the ini file so not sure we can sort it out by sorting ;)
                    Unless you have something magic in mind?

                      Nothing magic, but if order is important then maybe sorting the container be a better idea than relying on something that can be modified with a text editor.

                        Absolutely if the order has any logic to it.
                        Also I'm not sure poster will find QVector easy to access compared to a
                        map.

                            Or should we guess what the error is?

                                @poojakamshetty Please take a look at QVector documentation for insert() methods and fix your code. Hint: insert() has two parameters (as the error message already suggests).

                                  Hi
                                  Actually you might want to use append instead
                                  https://doc.qt.io/qt-5/qvector.html#append
                                  values.append(QPair<QString, QString>(childKey, settings.value(childKey).toString()));
