Result of DBUS call

[conexion2000]

Hi,
I am writing some app with notification, but currently I am stuck. I wanted to add actions to notifications, but I don't know how to read the result. Here is the code:

knotify = new QDBusInterface("org.kde.VisualNotifications", "/VisualNotifications", "org.kde.VisualNotifications");
//some args initialisation
QDBusReply<QString> reply = knotify->callWithArgumentList(QDBus::Block, "Notify", args);
if (reply.isValid())
     qDebug() << reply.value();
else
     qDebug() << "Error";

knotify = new QDBusInterface("org.kde.VisualNotifications", "/VisualNotifications", "org.kde.VisualNotifications");
//some args initialisation
QDBusReply<QString> reply = knotify->callWithArgumentList(QDBus::Block, "Notify", args);
if (reply.isValid())
     qDebug() << reply.value();
else
     qDebug() << "Error";

To copy to clipboard, switch view to plain text mode 

Everything works nicely, popup is shown, but commandline shows "Error" that means QDBusReply is invalid.
How can I read the result of this function?
This should return ID of the notification for further usage.

I think you should listen to the ActionInvoked signal from the notification object.

Thanks for your reply but it is not what I meant. This is gonna be next step, but at first I need to obtain ID of this notification, beacause ActionInvoked returns ID also and then I now how to react on ActionInvoked.

(with ActionInvoked I get only ID and action number, but I don't know what notification it is.)

This works for me:

#include <QtGui>

int main(int argc, char **argv){
  QApplication app(argc, argv);
  QDBusInterface knotify("org.kde.VisualNotifications", "/VisualNotifications", "org.kde.VisualNotifications");
  QVariantList args;
  args << QString("Appname");
  args << QVariant(QVariant::UInt);

  args << QStringList();

  args << 5000;
  QDBusMessage call = knotify.callWithArgumentList(QDBus::Block, "Notify", args);
  uint id = call.arguments().first().toUInt();
  qDebug() << id;
  return app.exec();
}

  qDebug() << id;
  return app.exec();
}

The return value is integer, so try QDBusReply<uint> instead of QDBusReply<QString>. This works for me as well.

Bingo! Thanks for help.
