Question subscribing for signals...

Hi,

i hope someone can help me - i just started with Dbus and struggeling to subscibe to the PropertiesChanged signal of org.freedesktop.DBus.Properties.

I googleing for 3 days and hope that an expert will see my fault in a minute :)

I try to subscibe to the PropertiesChanged signal of org.freedesktop.DBus.Properties using the follwing code:

DBusGProxy* purple_proxy = dbus_g_proxy_new_for_name (bus,

"org.bluez",

"/org/bluez/hci0",

"org.freedesktop.DBus.Properties");

GType VariantMap = dbus_g_type_get_map ("GHashTable", G_TYPE_STRING, G_TYPE_VARIANT);

GType MyStringList = dbus_g_type_get_collection("GPtrArray",G_TYPE_STRING);

dbus_g_object_register_marshaller(g_cclosure_user_marshal_VOID__STRING_BOXED_BOXED,

G_TYPE_NONE, G_TYPE_STRING, VariantMap,MyStringList, G_TYPE_INVALID);

dbus_g_proxy_add_signal (purple_proxy, "PropertiesChanged",

G_TYPE_STRING,

VariantMap,

MyStringList,

G_TYPE_INVALID);

dbus_g_proxy_connect_signal (purple_proxy,

"PropertiesChanged",

G_CALLBACK (properties_changed_proxy),

bus,

NULL);

I dont get an error but my callback wouldn't be called.

I used dbus monitor to see that the signal is fired.

Maybe my "arguments list" for registering the signal is wrong.

/*

signal void org.freedesktop.DBus.Properties.PropertiesChanged(QString interface,

QVariantMap changed_properties,

QStringList invalidated_properties)

*/

Thanks for your help

Tobias
