Control Your Linux Desktop with D-Bus
Now that you know how to perform D-Bus calls and how to handle D-Bus signals, you can get started automating tasks on your desktop. If you are a Linux power user, D-Bus definitely should be in your vocabulary.
There is much more to D-Bus than I could show you in this article, but with qdbusviewer, qdbus, dbus-send and dbus-monitor, you can explore the possibilities yourself. If you want to create some more complex automation tasks with D-Bus, the Python and Ruby programming languages are a good fit. Consider the tutorials mentioned in the Resources, and then just let your imagination flow.
If you're a software developer, the part I didn't cover here is registering a service. This is the other side of the D-Bus story. If you register a service, you can provide objects to other applications via D-Bus.
