QDbus, capture ProprietiesChange arguments not working

marcelnitan

I'm trying to capture a dbus signal on my device and it doesn't work anymore. It worked fine when proprietyChanged function had to arguments but after I've tried adding them using an example I've found on stackoverflow it stopped working,

dbus-monitor

method call time=1669374173.364583 sender=:1.32 -> destination=:1.82 serial=2375 path=/org/droidian/Flashlightd; interface=org.droidian.Flashlightd; member=SetBrightness
   uint32 0

signal time=1669374173.368365 sender=:1.82 -> destination=(null destination) serial=190 path=/org/droidian/Flashlightd; interface=org.freedesktop.DBus.Properties; member=PropertiesChanged
   string "org.droidian.Flashlightd"
   array [
      dict entry(
         string "Brightness"
         variant             int32 0
      )
   ]
   array [
   ]
method return time=1669374173.368570 sender=:1.82 -> destination=:1.32 serial=191 reply_serial=2375

code

PowerControl::PowerControl(QObject *parent) : QObject(parent)
{   
}

PowerControl::~PowerControl()
{

}

void PowerControl::start()
{
    bool conn = QDBusConnection::sessionBus().connect("", "/org/droidian/Flashlightd", "org.freedesktop.DBus.Properties", "PropertiesChanged", this, SLOT( propertyChanged(QString, QVariantMap, QStringList) ));
    qDebug() << QDBusConnection::sessionBus().isConnected();
}

void PowerControl::proprietyChanged(QString interface, QVariantMap changed_properties, QStringList invalidated_properties)
{
    qDebug() << QString("properties of interface %1 changed").arg(name);
        for (QVariantMap::const_iterator it = map.cbegin(), end = map.cend(); it != end; ++it) {
            qDebug() << "property: " << it.key() << " value: " << it.value();
        }
}
