| Editors and views</h2> |
| <P CLASS="Intro">Prior to commencing the Workbench tutorials found in this section, |
| it is important to first be familiar with the various elements of the Workbench. |
| A Workbench consists of:</p> |
| <ul> |
| <li> |
| perspectives</li> |
| <li> |
| views</li> |
| <li> |
| editors</li> |
| </ul> |
| <p CLASS="Intro">A perspective is a group of views and editors in |
| the Workbench window. One or more perspectives can exist in a single Workbench |
| window. Each perspective contains one or more views and editors. Within a |
| window, each perspective may have a different set of views but all perspectives |
| share the same set of editors.</p> |
| <p CLASS="Intro">A view is a visual component within the Workbench. It is typically |
| used to navigate a list or hierarchy of information (such as the resources in the Workbench), |
| or display properties for the active editor. Modifications made in a view are saved immediately.</p> |
| <p CLASS="Intro">An editor is also a visual component within the Workbench. It is typically used to edit or browse a |
| resource. The visual presentation might be text or a diagram. |
| Typically, editors are launched by clicking on a resource in a view. |
| Modifications made in an editor follow an open-save-close lifecycle model. |
| </p> |
| <p CLASS="Intro">Some features are common to both views and editors. We use the |
| term "part" to mean either a view or an editor. Parts can be active |
| or inactive, but only one part can be active at any one time. The active |
| part is the one whose title bar is highlighted. The active part is the target |
| for common operations like cut, copy and paste. The active part also determines |
| the contents of the status line. If an editor tab is not highlighted it indicates |
| the editor is not active, however views may show information based on the last |
| active editor.</p> |
| <p CLASS="Intro">In the image below, the Project Explorer view is active. </p> |

| <P CLASS="Intro">Clicking on the Outline view causes the Outline's title bar to |
| become highlighted and the Project Explorer's title bar to no longer be highlighted, |
| as shown below. The Outline view is now active. </p> |
