Creating a newline in a string

[Ch1156]

Ok so i'm working with a GUI program that has a text field but it doesnt have a text box, so I figure i can try creating one, but I cant figure out how to add a new line to the text, how would I do that?

This is what I have so far. it's just a snippet.

string f;

        f = text_box->GetText();

        if(f.length() >= 10)
        {
            cout << "Test" << endl;
            f += '\n';
        }

I guess that you're looking for the insert function of the string:

With this you can insert a new line at the position 10
