[Gambas-user] Monitoring DBus-Signal ?

[Hans Lehmann]

Hello,

I want to see the signal 'VolumeChanged' sent by the application 
'org.gtk.Private.MTPVolumeMonitor' with the interface 
'org.gtk.Private.RemoteVolumeMonitor'. The dbus-monitor program shows:

signal sender=:1.10 -> dest=(null destination) serial=319 
path=/org/gtk/Private/RemoteVolumeMonitor; 
interface=org.gtk.Private.RemoteVolumeMonitor; member=VolumeChanged

I am not able to observe this DBus signal. The project is attached. The 
project follows the documentation under the link: 
http://gambaswiki.org/wiki/doc/dbus#t4 .

Sincerely,
Hans

Code:

' Gambas class file

Public hDBusObject As New DBusObject
Public hDBusSignal As DBusSignal

Public Sub Form_Open()

   FMain.Resizable = False
   DBus.Debug = True
   DBus.Unique = True
   DBus.Session.Register(hDBusObject, Application.Path) ' o.k.

   hDBusSignal = New DBusSignal(DBus.Session, 
"org.gtk.Private.RemoteVolumeMonitor") As "MySignal"

End

Public Sub MySignal_Signal(Signal As String, Arguments As Variant[])

   Print Signal
   Print Arguments.Count

' If Signal = "VolumeChanged" Then Print ("USB-Stick or SD-Card 
registered!")
' If Signal = "VolumeRemoved" Then Print ("USB-Stick or SD-Card 
deregistered!")

End
