Antonio OREFICE reported a new bug.

Summary
-------

gb.dbus: Please implement "PropertiesChanged" on interface "org.freedesktop.DBus.Properties"

Type             : Request
Priority         : Medium
Gambas version   : 3.10
Product          : Unknown


Description
-----------

I'm trying to write an mpris2 compatible player, but i'm stuck on emitting signals via interface=org.freedesktop.DBus.Properties; member=PropertiesChanged.
What i've done so far is the following:

I registered into dbus by the following:
DBus.Session.Register(mpris, "/org/mpris/MediaPlayer2", ["org.mpris.MediaPlayer2", "org.mpris.MediaPlayer2.Player", "org.freedesktop.DBus.Properties"])
(yes, the last interface was my last hope)

...next i tried to emit something via the following handler:
Event org_freedesktop_DBus_Properties_PropertiesChanged(out1 As String, out2 As Collection)

..and the following call:
DBus["/org/mpris/MediaPlayer2"].Raise(mpris, "org.freedesktop.DBus.Properties.PropertiesChanged", ["org.mpris.MediaPlayer2.Player", properties_changed_collection])

With dbus explorer all seems to be right:
signal time=1527089280.104317 sender=:1.5573 -> destination=(null destination) serial=642 path=/org/mpris/MediaPlayer2; interface=org.freedesktop.DBus.Properties; member=PropertiesChanged
   string "org.mpris.MediaPlayer2.Player"
   array [
      dict entry(
         string "PlaybackStatus"
         variant             string "Playing"
      )
   ]

but according to qdbusviewer, i just duplicated the interface, and the mpris2 client seems unaware of the emitted signal.

Am i doing something wrong/is there a way right now to add "PropertiesChanged" into the existing interface or is something to be done right into gb.dbus?

Thanks!
