Create a generic system for subscribing to events generated by other programs.
| | Status: | Open | | Priority: | Low As prioritized by the OS4 development team | | Category: | system/general | | Description: | The project shall be divided into two parts:
A broker commodity
This components act as a service, receiving messages from posters and sending messages to subscribers.
An access library
This library shall contain all methods needed to communicate with the broker including functions for deallocating messages.
Example of use
An application implements a drag&drop feature. It identifies the window the drop was made on and then requests the broker to forward some data to the window.
The broker checks if there's any subscriber owning that window and sends a copy of the message to that subscriber.
The subscribing application receives a message from the broker that something was dropped on it and acts on the message. | | Created by: | orgin | | Created at: | 20091209 14:19 | | Deadline: | Not set | | Finished at: | Not finished | | Last update: | 20140402 19:09 | | Assigned to: | Not assigned |
