Read map type from QDBusArgument

[volcano]

Hi All,

Here's the code attached

QDBusInterface busInterface(
                        DBUS_NETWORK_MANAGER_SYSYEM_SERVICE_NAME,
                        m_strDhcp4Config.toAscii().data(),
                        DBUS_NETWORK_MANAGER_SYSTEM_PROPERTIES_INTERFACE,
                        QDBusConnection::systemBus());
 
            QDBusReply< QVariantMap > result = busInterface.call(GETALL,
                                                                 DBUS_NETWORK_MANAGER_SYSTEM_ACTIVE_DHCP4CONFIG_INTERFACE);
 
            if(result.isValid())
            {
                qDebug() << "Success";
                QVariantMap propertiesMap = result.value();
                QDBusArgument optionsArgument = qvariant_cast<QDBusArgument>(propertiesMap.value("Options"));
 
                propertiesMap.clear();
                optionsArgument.beginArray();
 
                while ( !optionsArgument.atEnd() ) {
                    QVariant key;
                    QVariant value;
                    optionsArgument.beginMapEntry();
                    optionsArgument >> key >> value;
                    optionsArgument.endMapEntry();
                    propertiesMap.insert( key, value);
                }
 
                optionsArgument.endArray();
            }

QDBusInterface busInterface(
                        DBUS_NETWORK_MANAGER_SYSYEM_SERVICE_NAME,
                        m_strDhcp4Config.toAscii().data(),
                        DBUS_NETWORK_MANAGER_SYSTEM_PROPERTIES_INTERFACE,
                        QDBusConnection::systemBus());

            QDBusReply< QVariantMap > result = busInterface.call(GETALL,
                                                                 DBUS_NETWORK_MANAGER_SYSTEM_ACTIVE_DHCP4CONFIG_INTERFACE);

            if(result.isValid())
            {
                qDebug() << "Success";
                QVariantMap propertiesMap = result.value();
                QDBusArgument optionsArgument = qvariant_cast<QDBusArgument>(propertiesMap.value("Options"));

                propertiesMap.clear();
                optionsArgument.beginArray();

                while ( !optionsArgument.atEnd() ) {
                    QVariant key;
                    QVariant value;
                    optionsArgument.beginMapEntry();
                    optionsArgument >> key >> value;
                    optionsArgument.endMapEntry();
                    propertiesMap.insert( key, value);
                }

                optionsArgument.endArray();
            }

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,

Minor error in code

optionsArgument.beginMap();
while ( !optionsArgument.atEnd() ) {
	QVariant key;
	QVariant value;
	optionsArgument.beginMapEntry();
	optionsArgument >> key >> value;
	optionsArgument.endMapEntry();
	propertiesMap.insert( key, value);
}
optionsArgument.endMap();

optionsArgument.beginMap();
while ( !optionsArgument.atEnd() ) {
	QVariant key;
	QVariant value;
	optionsArgument.beginMapEntry();
	optionsArgument >> key >> value;
	optionsArgument.endMapEntry();
	propertiesMap.insert( key, value);
}
optionsArgument.endMap();

Kindly suggest me what should I do

While not directly related to your code, some general ideas:

- have you evaluating using the Qt library for network manager instead of using D-Bus directly?
- assuming network manager has the usual XML interface definition files, how about letting qdbusxml2cpp generate an interface class for you?

Cheers,
