I want to make an application that will be using GDBus, but the API reference is too difficult (which function to start with? What is the best way? Am I doing it right?..) and the code examples I could find online are written in C. I saw a similar thread but it is for PyDBus and what I want is use o…

Success!! After centuries of battle with many things, I was able to make a working example ! Yeah! I have included the source code below. ▶ server.py ▶ client.py Fire up terminal and run server.py like python3 server.py. Client is an interactive one, so run it like this : python3 -i client.py. Then i…

Thanks that was great, but the server is written in C, can that be converted to Python? (Let me try my best in converting though)

I’m stuck at handling signal connection, this is my progress : import gi from gi.repository import Gio, GLib, GObject # Changed from Alarm to Printer for simplicity class Printer(Gio.DBusInterfaceSkeleton): def __init__(self, **kwargs): Gio.DBusInterfaceSkeleton.__init__(self) …

Where the parameter type is a callback, you can pass a Python function and it will “just work”. In your example - what happens if you pass the on_name_acquired function directly to bus_own_name() as the 5th parameter?

I’m sorry, the error was on line number 22: File "service.py", line 22, in on_name_acquired Printer.connect("handle-configure", on_handle_configure, None) TypeError: descriptor 'connect' requires a 'gi._gi.GObject' object but received a 'str' Updated the code.

Try replacing Printer with printer on line 22. Printer refers to the class, while printer refers to the instance of the class you created.

Thanks for that, a typo :joy: :man_facepalming: Now I’m getting an unknown signal “handle-configure” error? Is it a valid signal for DBus-Skeleton?

Now I’m getting an unknown signal “handle-configure” error? Is it a valid signal for DBus-Skeleton? No, I don’t see it in the documentation. You can use the .add_interface() method to implement the actual D-Bus interface that you want.

Ahhh its confusing. There are two things, Gio.DBusInterfaceSkeleton, which has export method but not add_interface and Gio.DBusObjectSkeleton which has your add_interface method but not export. Which one to use? How to use? Can you give an example?

I believe you should create an InterfaceSkeleton, add the methods you want to publish there, then add the interface to an ObjectSkeleton and export that.

Minimal example of GDBus in Python
