void textLoader(Text *TmplineMenu) {

        string menuLine, tmpStr;
        ifstream infile;

        infile.open("Tools/datiMenu.txt");
        while (getline(infile, menuLine)) {

                size_t position = menuLine.find("||") + 1;
                menuLine.insert(position, "\n");
                tmpStr += menuLine;
                tmpStr += '\n';

You calculate the space the text takes up and insert a line break when it reaches a certain width.
