Hi,
I am trying to understand how I could read out the values of a complex dbus
reply
I want to access following
// org.freedesktop.DBus.ObjectManager.GetManagedObjects (out
DICT<OBJPATH,DICT<STRING,DICT<STRING,VARIANT>>>
objpath_interfaces_and_properties);
https://dbus.freedesktop.org/doc/dbus-specification.html#standard-interface…
In my code I do
TQT_DBusConnection connection = TQT_DBusConnection::systemBus();
if (!connection.isConnected())
tqFatal("Failed to connect to system bus");
TQT_DBusProxy proxy(connection);
proxy.setService("org.bluez"); // who we work with
proxy.setPath("/"); // which object inside the peer work with
proxy.setInterface("org.freedesktop.DBus.ObjectManager");
if ( connection.isConnected() ) {
if ( proxy.canSend() ) {
TQValueList<TQT_DBusData> params;
TQT_DBusMessage reply =
proxy.sendWithReply("GetManagedObjects",
params );
if ( reply.type() != 2 || reply.count() != 1 || reply[0].type()
!=
TQT_DBusData::Map)
tqFatal("GetManagedObjects failed");
kdDebug() << "TQT_DBusMessage: Reply " <<
reply.type() << endl;
kdDebug() << "Type: TQT_DBusDataMap " <<
reply[0].type() << endl;
kdDebug() << "Count : " << dict.count()
<< endl;
TQT_DBusDataMap<TQT_DBusObjectPath> dict( reply[0] );
for
(TQT_DBusDataMap<TQT_DBusObjectPath>::const_iterator it =
dict.begin(); it != dict.end(); ++it) {
kdDebug() << (*it).type() << endl;
}
}
else
tqFatal("proxy can not send messages");
}
else
tqFatal("manager is not connected");
result is
./bttest
TQT_DBusMessage: Reply 2
Type: TQT_DBusDataMap 16
Count : 0
but when I run
gdbus
call -y -d "org.bluez" -o "/" -m
"org.freedesktop.DBus.ObjectManager.GetManagedObjects"
({objectpath '/org/bluez': {'org.freedesktop.DBus.Introspectable': @a{sv}
{}, 'org.bluez.AgentManager1': {}, 'org.bluez.ProfileManager1':
{}, 'org.bluez.Alert1': {}, 'org.bluez.HealthManager1': {}}},)

Thank you for being so helpful and supportive with this question ;-)
Here is an example code for the future generation
TQT_DBusConnection connection = TQT_DBusConnection::systemBus();
if (!connection.isConnected())
tqFatal("Failed to connect to session bus");
// create a proxy object for method calls
TQT_DBusProxy proxy(connection);
proxy.setService("org.bluez" ); // who we work with
proxy.setPath("/"); // which object inside the peer work with
proxy.setInterface ( "org.freedesktop.DBus.ObjectManager" ); // which
of
its interfaces we will use
TQValueList<TQT_DBusData> params;
TQT_DBusMessage reply = proxy.sendWithReply("GetManagedObjects",
params);
if (reply.type() != TQT_DBusMessage::ReplyMessage)
tqFatal("Call failed");
if ( reply.type() != TQT_DBusMessage::ReplyMessage || reply.count() != 1 ||
reply[0].type() != TQT_DBusData::Map)
tqFatal("Unexpected reply");
bool ok = false;
TQT_DBusDataMap<TQT_DBusObjectPath> names =
reply[0].toObjectPathKeyMap(&ok);
kdDebug() << "TQT_DBusMessage::ReplyMessage : " <<
reply.type() << endl;
kdDebug() << "TQT_DBusData::Map : " <<
reply[0].type() <<
endl;
kdDebug() << "Name1 : " <<
reply[0].typeName() <<
endl;
kdDebug() << "Size1 : " <<
names.count() << endl;
if (!ok) tqFatal("toTQStringList failed");
for (TQT_DBusDataMap<TQT_DBusObjectPath>::const_iterator it =
names.begin(); it != names.end(); ++it)
{
kdDebug() << "Name2 : " <<
(*it).typeName() <<
endl;
ok = false;
TQT_DBusDataMap<TQString> names1 = (*it).toStringKeyMap(&ok);
kdDebug() << "Size2 : " <<
names1.count() <<
endl;
if (!ok) tqFatal("toTQStringList failed");
for (TQT_DBusDataMap<TQString>::const_iterator it1 =
names1.begin();
it1 != names1.end(); ++it1)
{
ok = false;
kdDebug() << "Name3 : "
<< (*it1).typeName() <<
endl;
TQT_DBusDataMap<TQString> names2 =
(*it1).toStringKeyMap(&ok);
if (!ok) tqFatal("toTQStringList failed");
kdDebug() << "key : "
<< TQString(it1.key())
<< endl;
kdDebug() << "Size3 : "
<< names2.count() <<
endl;
}
}
