- """Multi-consumer multi-producer dispatching mechanism
- This Python library is used e.g. in wxGUI. The purpose of the library
- is to provide mechanism for communication between objects in wxGUI.
- The library consists of two parts:
- * the Python Signal API which will be used in wxGUI, and
- * this 3rd party package PyDispatcher does the hard work.
- In short, simple function calls are not sufficient in the GUI, event
- driven and large environment with many persistent objects because
- using simple function calls would lead to tightly coupled code. Thus,
- some better mechanism is needed such as Observer design pattern. In
- GRASS GIS, we use the Signal system which is similar to Signals used in
- PyQt and other frameworks. As the underlying library, we have chosen
- PyDispatcher because it provides very general API which enables to
- implement Signal API, wide and robust functionality which makes
- implementation and use of Signals easier.
- PyDispatcher metadata:
- :version: 2.0.3
- :author: Patrick K. O'Brien
- :license: BSD-style, see license.txt for details
