Hi All,

Here's the code attached

Qt Code: 
  1. QDBusInterface busInterface(
  2.                         DBUS_NETWORK_MANAGER_SYSYEM_SERVICE_NAME,
  3.                         m_strDhcp4Config.toAscii().data(),
  4.                         DBUS_NETWORK_MANAGER_SYSTEM_PROPERTIES_INTERFACE,
  5.                         QDBusConnection::systemBus());
  6.  
  7.             QDBusReply< QVariantMap > result = busInterface.call(GETALL,
  8.                                                                  DBUS_NETWORK_MANAGER_SYSTEM_ACTIVE_DHCP4CONFIG_INTERFACE);
  9.  
  10.             if(result.isValid())
  11.             {
  12.                 qDebug() << "Success";
  13.                 QVariantMap propertiesMap = result.value();
  14.                 QDBusArgument optionsArgument = qvariant_cast<QDBusArgument>(propertiesMap.value("Options"));
  15.  
  16.                 propertiesMap.clear();
  17.                 optionsArgument.beginArray();
  18.  
  19.                 while ( !optionsArgument.atEnd() ) {
  20.                     QVariant key;
  21.                     QVariant value;
  22.                     optionsArgument.beginMapEntry();
  23.                     optionsArgument >> key >> value;
  24.                     optionsArgument.endMapEntry();
  25.                     propertiesMap.insert( key, value);
  26.                 }
  27.  
  28.                 optionsArgument.endArray();
  29.             }
To copy to clipboard, switch view to plain text mode 

I get this error "QDBusArgument: write from a read-only object" on the lines "optionsArgument.beginMapEntry();" and "optionsArgument.endMapEntry();"

The response I'm looking to parse is
"{u'broadcast_address': u'10.244.10.255',
u'dhcp_lease_time': u'691200',
u'dhcp_message_type': u'5',

u'routers': u'10.244.10.1',
u'subnet_mask': u'255.255.255.0'}"

Kindly suggest how can I parse this value appropriately..
Thanks,
