Python DBUS examples including emitting/receiving signals and calling proxied methods.

Python DBUS examples

A collection of python DBUS examples.

Abstract

The first time I had to deal with python and DBUS I was overwhelmed by the lack of concrete examples, so this repository was born. More documentation may be found in the comments.

Dependencies

The following are python dependencies:

• dbus-python
  • relies on libdbus-1-dev
• PyGObject
  • relies on libgirepository1.0-dev

Usage

In your first terminal run the dbus monitor and grep for the examples methods:

dbus-monitor | grep /tld/domain/sub

In a second terminal run the reciever:

./receiver.py

The receiver has a catch all handler, so a lot of output is expected there.

in a third terminal you can now either:

• Run the invoker, which will call the proxxied receivers Test object methods:

    ./invoker.py
  

  The invoker will invoke 3 Methodes on the receiver:

  • foo: This will simply return Foo as a string
  • fail: Will trigger an exception in the receiver which the invoker can handle
  • quit: Will stop the receiver

• run the emitter, which will emit a test signal and a quit signal:

    ./emitter.py
  

After running either of them, the receiver will be stopped.
