Qt example illustrating how to write list of QVariantMap into a settings file.

qVariantMapToSettings.cpp

// Qt includes
#include <QSettings>
#include <QVariantMap>

// STL includes
#include <cstdlib>

int main(int, char*[])
{
  
  QSettings settings("qVariantMapToSettings.ini", QSettings::IniFormat);
  
  QList<QVariantMap> list;
  {
    QVariantMap map;
    map["string"] = QVariant("bar");
    map["bool"] = QVariant(true);
    list << map;
  }
  {
    QVariantMap map;
    map["string"] = QVariant("foo");
    map["bool"] = QVariant(false);
    list << map;
  }
  
  
  settings.clear();
  settings.beginWriteArray("settings");
  for (int i = 0; i < list.size(); ++i)
    {
    settings.setArrayIndex(i);
    settings.setValue("setting", list.at(i));
    }
 
  return EXIT_SUCCESS;
