I am new to GDbus programming. I need to implement a simple Dbus send-receive message (Signals) using Dbus Glib. I tried to google some sample programs, but couldn't find.
Can anyone post any such sample program or point me to some sample program tutorial?
Thanks in advance...
Thanks, SB

Register service The dbus-daemon scan the /usr/share/dbus-1/system-services for system services. We should create a simple service file there. The service file has to be named after bus name of the service. Remark: ${USER} should be replaced with username which is used in the policy file.
A signal in DBus consists of a single message, sent by one process to any number of other processes. That is, a signal is a unidirectional broadcast.
The dbus-launch command is used to start a session bus instance of dbus-daemon from a shell script. It would normally be called from a user's login scripts. Unlike the daemon itself, dbus-launch exits, so backticks or the $() construct can be used to read information from dbus-launch.
The dbus-send command is used to send a message to a D-Bus message bus. See https://www.freedesktop.org/wiki/Software/dbus/ for more information about the big picture.
I found a book that talks about GDBus, gdbus-code gen, GVariant and all the relevant bits and pieces:

As outlined above, I would start with the wiki article to understand the concepts:
