SWT

(Standard Widget Toolkit)

4. SWT

IBM developed VisualAge: IDE coded in Smalltalk

VisualAge becomes Open Source project: Eclipse, intended to compete against other IDEs such as Microsoft Visual Studio

Why a whole new GUI toolkit?

• native look and feel

• native performance

5. SWT 6. SWT: Comparison with AWT/Swing

AWT: thin wrapper around native UI widgets

SWT AWT wrapper Native UI widgets Native Graphics Library Swing wrapper 7. SWT: Comparison with AWT/Swing

Swing: full-blown 100% Java widgets

SWT AWT wrapper Native UI widgets Native Graphics Library Swing wrapper 8. SWT: Comparison with AWT/Swing

SWT

• • wrapper around native UI widgets: GTK+, Motif, win32

• • missing functionality is developed in Java at SWT level

SWT AWT wrapper Native UI widgets Native Graphics Library Swing wrapper 9. SWT: Comparison with AWT/Swing

SWT

• Does not implement Model-View-Controller (JFace)

• Is relatively simpler than Swing

10.

JFace

11. JFace - Resources

Provides registries that hold Images and Fonts

12. JFace - Actions

Actions to allow users to define their own behavior and to assign that behavior to components (menu items, tool items, push buttons, etc.

13. JFace - MVC

Viewer classes that handle data populating, sorting, filtering, and updating widgets (the MVC pattern )

14. JFace - User Interaction

Defines standard dialogs and wizards, and defines a framework for building complex interactions with the user

15. JFace - Long-running operations

Long-running operations that require progress indicators or allow user cancellation of the operation.

16. JFace - SWT

JFace is completely dependent on SWT, but SWT is not dependent on JFace.

The Eclipse Workbench is built on both JFace and SWT. In some instances, it bypasses JFace and accesses SWT directly.

Workbench Native UI SWT JFace 17. JFace - Summary

Primary goal is to free the developer up, letting to focus on the implementation of an application without having to be concerned with the underlying widget system or solving problems that are common in almost all UI applications.

18.

OSGi

(Open Services Gateway initiative)

19. OSGi

OSGi is an independent, non-profit corporation

Open specifications for the delivery of managed services to networked environments

The specification define the OSGi Service Platform:

• the OSGi framework

• a set of standard service definitions

The core part of the specifications is a framework that defines an application life cycle model and a service registry.

20. OSGi - Services Platform Publish Discover Bind Bundle Service Registry Service Provider Service Requester 21. OSGi Service Definition

A service is defined by:

• the service interface - Java class or interface,

• the service properties - name and value pairs

22. OSGi Services

Wide range of services is already defined ...

Security; Module; Life Cycle, and Service Layers; Framework API; Package Admin Service; Start Level Service; Conditional Permission Admin; Permission Admin Service; URL Handlers Service; Log Service; HTTP Service (runs servlets); Device Access; Configuration Admin Service; Metatype Service; Preferences Service; User Admin Service; Wire Admin Service; I/O Connector Service; Initial Provisioning; UPnP Device Service; Declarative Services; Event Admin Service; Deployment Admin; Auto Configuration; Application Admin Service; DMT Admin Service; Monitor Admin Service; Foreign Application Service; Service Tracker; XML Parser Service; Position; Measurement and State; Execution Environments

... plus all your own services.

23. OSGi Features

Lazzy loading

Service decoupling

Mix'n'Match services from different vendors (e.g. Spring Dynamic Modules)

Lifecycle control

24. OSGi Eclipse Equinox

Equinox is one of many OSGi implementations

• Knopflerfish

• Apache Felix

Solid base for Eclipse platform

25.

Eclipse Plug-ins

26. Eclipse Plug-ins

OSGi bundle

Provide extension points

Contribute to extension points

27. Eclipse Plug-ins host plug-in exposes extension point extender plug-in contributes to an extension point extension point plug-in: org.eclipse.ui WorkbenchPlugin actionSets plug-in: org.eclipse.help.ui Help -> Help Contents menu item 28.

Rich Client Platform (RCP)

29. RCP

Eclipse RCP is a platform for building and deploying rich client applications.

This is the heart of any Eclipse based application
