Eclipse 3.1 IDE Overview

Eclipse IDE Overview Workspace Workbench Resources Perspectives Views Preferences Plugins

The Workspace, the Workbench and Resources The “Workspace” is the directory where Eclipse will store your projects. You can have as many Workspaces as you like, although only one is active at any time. You can choose one as a default which Eclipse will automatically select each time you start it. The “Workbench” is the general name given to the complete window space the Eclipse IDE occupies on your screen. The Workbench will have a Menu Bar, a Tool Bar, a status area and a “Perspective” which may contain several “Views” and “Editors The things that Eclipse operates on are, in general, called “Resources”. Your Workspace is a Resource, as is any Project you create, and as are all the files in your Projects. Eclipse makes only token efforts to operate on files which are not contained in a Project in your Workspace

Views Views are frames which display data in a particular way. For example, the “Package Explorer” view (left) arranges its display around the structure of Java packages, while the “Resource Navigator” view (right) reflects the directory structure of the project as it exists on disk.

Views The “Outline View” shows the structure of the current file

Editors Most perspectives will have an editor area and some views. Editors can be associated with specific file types, or you can manually open a file with a specific editor. If there’s a system association of a file type with an application that’s not recognized by Eclipse, that application will be automatically opened, with sometimes surprising results. Many editors can be open at once, but only one can be active. The menus and toolbar may change to include functions unique to the active editor.

Preferences The Eclipse IDE has many parameters which you can change to suit your personal preferences. The Preferences settings are accessed through the Window->Preferences menu selection. Each feature or plugin that is installed in an Eclipse instance can add its own set of preferences and can access the global preferences.

Preferences

Eclipse Help System The Eclipse IDE has a comprehensive help system which can be accessed via the Help menu. Many GUI items on the Workbench have context-sensitive help links which allow you to directly access the appropriate section of the Help system by pressing “F1” while the item has focus.
