Eclipse Rich Client Platform
The amazing simplicity of creating RCP application
Lars Vogelhttp://www.vogella.de
• What is RCP?
• OSGi
• Modular Architecture
• RCP
• e4 (lets see if we have time….)
… and some life hacking
Agenda
• Local running application using the native widget toolkit
• Based on the Eclipse runtime and technology
What is an Eclipse RCP application?
Eclipse (RCP) applications are written in
Java
in little pieces (plugins)
Extensible Application - Firefox
Plugins The Browser
OSGiDynamic module system in Java
Bundle
Smallest deployment and development component in OSGi
Bundle == Plugin
BundlePlugin
Each Plugin defines its
available API
Each Plugin defines also its dependencies
MANIFEST.MF –
Additional metadata for OSGi runtime
Runtime (OSGi) makes sure the API contacts are
fulfilled
Demo
Standard Java App Modular Java App
OSGi – Enforced Modularity
Anatomy of Eclipse RCP
In Eclipse everything is a plugin (except the core runtime)

Why Eclipse RCP?

A closer look
Your first RCP app in < 10 secs
• Defines OSGi bundle properties
Important configuration file- MANIFEST.MF -
You said that already in the OSGi chapter ….
• Defines extensions and extension points
Important configuration files- plugin.xml -
Extensions
Extension Points
Provide functionality to predefined slots (== extension points)
Define places where others (== extensions) can provide functionality
The building blocks
• Thin layer upon the native GUI libraries • JNI calls• Not a lot of convenient functionality
SWT - Standard Widget Toolkit
• JFace– UI toolkit that provides helper classes for developing UI
features– Makes SWT nicer but does not hide its complexity– Tables / TreeViewer / Dialogs / – Databinding
• Workbench – multi-window environment – manages views, editors, perspectives
JFace & Workbench
Lets create a RCP app
• Find in Eclipse which parts you are looking at• Make coding analysis and re-use extremly easy• Shortcut Alt+Shift+F1
• Add org.eclipse.pde.runtime and org.eclipse.ui.forms as dependency to have Plug-in Spy in your own RCP application

Excursus: Plug-in Spy
Lars Vogel 4/22/2009
How did he do it?
Plugin Spy = Shortcut Alt+Shift+F1
e4 ?
Eclipse e4
Eclipse e4 is the incubator project which will produce the Eclipse 4.0 SDK
Eclipse e4 Scope
Make development for Eclipse easier
Eclipse 3.x programming model
• Complex
• Lots of API
• Platform functionality via singletons
• Not easy to test
• Not a consistent way to define the UI
Eclipse e4 – Building blocks
Declarative Styling
Modeled Workbench
Rendering Engine
Dependecy Injection
Context
Core Services
