    with respect to your ini file from your first post you should call:

    iniSettings->beginGroup("Personal");
    iniSettings->value("Age");
    iniSettings->endGroup();
    

    or alternatively (if you don't have a group set!):

    iniSettings->value("Personal/Age");

      And in addition to what @raven-worx says, you need to use this constructor if you want to specify the filename.

      Otherwise QSettings calculates the filename itself.

      Qt has to stay free or it will die.

          yes i just wanted to add as @aha_1980 said.
          Use the mentioned constructor, since in your case it is not required to mess with the scopes.

            @raven-worx okay, I have included in the constructor itself.
            code: iniSettings=new QSettings(filename,QSettings::IniFormat,this);

                    with the usage of the right Constructor your ini-file should be read correctly now.
                    So now you can use QSettings::childGroups() to traverse all groups and read the values as i described above or with the use of QSettings::beginGroup() and QSettings::childKeys()

                    foreach( QString group, iniSettings->childGroups() )
                    {
                         // process group
                         iniSettings->beginGroup(group);
                             foreach( QString key, iniSettings->childKeys() )
                             {
                                    QVariant val = iniSettings->value(key);
                                    // process val
                             }
                         iniSettings->endGroup();
                    }

                          yes, i am still too lazy for such a convenient function to deprecate it also in my head ;)
