2. Welcome to the World of GumTree
During this talk, I’ll be presenting the latest development of our Graphical User Interface project, called GumTree, for the Neutron Beam Instrument Project at ANSTO.
What we are working on now is a Java based Graphical User Interface called GumTree
Our mission is to plant GumTree for our beamline users

4. Graphical User Interface
Control / Status
Data Visualization
Data Analysis
GUI
Client
Server
SIC Server
Motors
Detectors
Ancillaries
What we are doing now in ANSTO is to develop a common interface across different instrument
Basic Server-Client Architecture
Sequencer from PSI
Design Goals:
Instrument Control and Status
No prior knowledge of instrument control system commands
Live Data Visualization
Preview of the data acquired during experiment
Online / Offline Data Analysis
Perform analysis on acquired data

5. GUI for Scientific Experiment
Common problems for instrument control GUI
Compatibility
Ad-hoc. Every instrument is unique
Supported OS Platform
Platform dependent
Multi-Platform but limited GUI widget library. Poor look and feel
Functionality
A single application may not give access to all aspects of your scientific experiment
Interactivity
Lack of interactivity between different part of your system for running experiment
.…….your desktop may look like this

6. What make GumTree so unique to other scientific application?
This is a type

7. ……would it be nice to have something this like……

8. Now, thank for GumTree, it provides unified scientific workbench for doing anything you want with your experiment.

9. Integrated Scientific Experiment Environment
Extending the Design Goals:
Generic Scientific Workbench
Common and uniform interface for all instruments (reduce the user’s learning curve)
Support major platforms
While maintaining rich functionality and attractive interface
Intercommunication between modules
Exchange output between all parts of the system
Extensible
Customisable for different needs
User Friendly
Simplify the process for automated experiment
Computer Geek like come up with some kind of acronym, and we have come up with ISEE
Analogue of IDE
ISEE – Integrated Scientific Experiment Environment
Oh……I see…!!

10. GUM Enabled Application
Embedded data analysis support
Support various data formats
Use the widget set of your choice
Integrate with your visualization package
This philosophy fit perfectly into the Grand Unified Model
GUM – Grad Unified Model
Flexible approach
This concept fit perfectly into the GUM theory for the scientific experiment
GumTree is the key for GUM
Adaptable to different control systems
Grand Unified Model

11. Plug-in Based Architecture
Design Issue:
Scalability, Reusability
Easy to implement and integrate new features
Plug-in =

This is the overview of the GumTree Project.
All components are plugins!
What makes Eclipse Runtime so unique?
Eclipse Plugin Architecture
Primarily GumTree was designed to be the GUI for our RRR neutron instrument. Different instrument may require different configuration and customised views. Those will be captured into a set of instrument plug-ins and we have group those plug-ins under a subproject called GumNIX.

13. Extending GumTree
Programmers are usually lazy…….

14. Framework Design Principle
GumTree Framework
Two ways to extend GumTree:
API
Reusable library
Extension Point
minimal programming effort
without modifying based code
best for integrating unforeseen functionality into GumTree
Framework Design Principle
A well defined framework is the key for the extensibility of a platform.
GumTree Framework consists of API and extension point for extending and customising
API
Reusable library for creating components on the GumTree Platform
Extension Point
Extending the functionality of GumTree with minimal programming effort (demo)
And without modifying based code…for unforeseen

15. GumTree Base Technologies
Java
Cross platform
Rich set of Library
Object Oriented
New Release: J2SE 5.0 (new language enhancement: Generic Types, Variable Arguments, etc)
Large community: over 3 Million Developers (2003)
Being used in scientific area
e.g. ISAW
Eclipse
Originated as a Java IDE
Eclipse is used as both the IDE (JDT) and the building block of GumTree (RCP)
Books and Training are available in the market

16. Eclipse Rich Client Platform
Application Framework for making FAT client
OSGi Platform
A micro-kernel that provides secure and remotely managed service
Dynamic plugin installation / un-installation
An application framework that provides more than standard graphical widgets
Open Services Gateway Initiative (OSGi)
Originally used as a middle layer for service delivery for embedded device
Eclipse use subset of this

17. Eclipse Rich Client Platform
SWT: Native widgets (FAST!)
JFace: High level application components, eg Table, wizard
Plug-in architecture
Can be written in Java, C or some scripting language
Handling Large UI
Lazy Activation
Help System
Tomcat server (local, online)
Tutorial, dynamic help, popup help
Search Engine
Editor
GEF, EMF: Drawing Graphics / Data Modelling
GumTree and Eclipse
