This is a talk that I gave on GCF Application server, a cool product of VCreate Logic

1. GCF Application Server
…a sneak peak
By:
Aneesh Muralidharan

2. My intentions
 GCF Application Server

3. GCF
 A C++ framework for Qt applications
 Helps compose modules of an application as
dynamically loadable entities
 Provides GUI merging capabilities
 Provides object/functionality discovery
services
 Provides support for inter-process-
communication

4. A GCF Component

5. An application written in GCF

6. The enlightenment
 The push – pull effect
 The push !
 The pull !
 What if … ?!

7. The idea
 Have a web application
 Have a Qt application
 Create a possibility for them to communicate
to each other about what they think 

8. GCF Application Server

9. The architecture
 GCFMessage.js
 Javascript library
 Helps in issuing requests to
GCFApplicationServer
 Responses can be asynchronously handled
(AJAX Style)

10. …
 Sample code using GCFMessage.js

11. …
 GCFApplicationServer.php
 Acts as a forwarding agent
 POST data sent to it will be redirected to
GCFAppServer
 Waits for the server
 Relays back the response

12. …
 A simple GCFApplicationServer.php

13. …
 GCFMessage.xml format

14. ...
The application server
– GCFAppServerGUIXML
– ComponentLoaderComponent.xml

15. Component's XML file

16. ComponentLoaderComponent.xml

17. ...
 GCFApplicationServer listens on port 4232
 Received data packets that will be handled by
GCF::AppAccessPoint

18. …
 Construction of request GCF::Message
 GCF::AppAccessPoint invokes specified
methods in specified objects
 GCF::AppAccessPoint responds with a reply
GCF::Message
 This GCF::Message is then converted to
XML document
 This is written back to the same socket

19. …
 GCF::Message gets converted to XML

20. Re-cap
 So this is what happens…
Server
AP
C1 C2
PHP Internet
JS
4232
HTML

21. Demo
• A hello world app !

22. Questions ?!
