Hello again,

I finally discovered the GLib.HashTable class which should be more
appropriate than Gee.HashMap, but it doesn't help:
debian-gta02:~# cat dict.vala
using GLib;
using DBus;
public static void main (string [] args) {
DBus.Connection conn;
dynamic DBus.Object idleNotifier;
GLib.HashTable<string, int> timeouts;
conn = DBus.Bus.get(DBus.BusType.SYSTEM);
idleNotifier = conn.get_object("org.freesmartphone.frameworkd",
"/org/freesmartphone/Device/IdleNotifier/0",
"org.freesmartphone.Device.IdleNotifier");
// The GetTimeouts() DBus method returns a DBus Dictionary.
timeouts = idleNotifier.GetTimeouts();
}
debian-gta02:~# valac --pkg dbus-glib-1 --pkg glib-2.0 -o dict dict.vala
dict.vala:8.10-8.42: warning: unhandled error `DBus.Error'
conn = DBus.Bus.get(DBus.BusType.SYSTEM);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
dict.vala:10.14-10.39: warning: unhandled error `GLib.Error'
timeouts = idleNotifier.GetTimeouts();
^^^^^^^^^^^^^^^^^^^^^^^^^^
Compilation succeeded - 2 warning(s)
debian-gta02:~# ./dict
** (process:3942): WARNING **: No demarshaller registered for type
"gpointer"
** (process:3942): CRITICAL **: file dict.c: line 49: uncaught error:
No demarshaller registered for type "gpointer"
If I replace the line:
timeouts = idleNotifier.GetTimeouts();
with:
idleNotifier.GetTimeouts();
there is no more run-time error. Hence I guess the problem lies in
binding a DBus Dictionary to a HashTable...
How whould I proceed to correctly handle a DBus Dictionary in Vala?
Thanks in advance,
_Gilles.
