| <h1 class="Head">Editor area</h1> |
| <p class="Intro">The editor area is where you modify the contents of files in the Workbench.</p> |
| <p class="Para">Here is what the editor area looks like when multiple files are open and a text file is being |
| edited:</p> |
| <p class="Para"><img src="../images/Image230_editor_area.png" alt="Editor Area" border="0"></p> |
| <div class="Topic"> |
| <h2>Marker bar</h2> |
| <p class="Para">The marker bar is the vertical bar located at the left of the editor area.</p> |
| <p class="Para">Here is what the marker bar looks like:</p> |
| <p class="Para"><img src="../images/Image231_marker_bar.png" alt="Marker Bar" border="0"></p> |
| <h2>Markers</h2> |
| <p class="Para">Markers are displayed in the marker bar, to the left of the text editor.</p> |
| <p class="Para">Depending on the type of file displayed in the editor area, three kinds of markers may be |
| displayed:</p> |
| <ul class="UnorderedList"> |
| <li class="Item">Bookmarks</li> |
| <li class="Item">Task markers (for associated tasks)</li> |
| <li class="Item">Debugging breakpoints</li> |
| </ul> |
| <p class="Para">You can create and associate a marker with a specific line in a file by accessing the context menu |
| from the marker bar, which is directly to the left of that line.</p> |
| <p class="Para">Here is what the context menu of the marker bar for a java editor looks like:</p> |

| <h2>Types of editors</h2> |
| <p class="Para">The Workbench uses three types of editors:</p> |
| <ul class="UnorderedList"> |
| <li class="Item">Internal: These editors are launched inside the editor area in the Workbench window.</li> |
| <li class="Item">External: You can go outside the Workbench in the file system, edit a Workbench file outside the |
| Workbench, and save the edited file. For example, imagine that you add an SGML file to the Workbench. Later, you |
| go into the file system and open the file in an SGML editor, then save the file. The edited SGML file is still |
| represented in the Workbench, even though you did not edit the file in the Workbench. If you associate a file |
| type with an external editor in the Workbench ( <a class="command-link" href= |
| 'javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.ui.preferencePages.FileEditors)")'> |
| <img src="PLUGINS_ROOT/org.eclipse.help/command_link.svg" alt="command link"> <b>General > Editors > File |
| Associations</b></a> preference page), then the Workbench will launch this external editor.</li> |
| <li class="Item">ActiveX: On Microsoft Windows platforms, the Workbench makes use of ActiveX controls for |
| applications that allow for them. For example, Microsoft Word supports being embedded as an OLE document. Thus if |
| you have a <i>.doc</i> file in the Workbench, and Word is registered as the editor for <i>.doc</i> files in your |
| operating system, then opening the file will launch Word as an OLE document within the Workbench editor area. |
| Notice how OLE documents also add such features as menus and toolbar buttons.</li> |
| </ul> |
| <p>The following illustrates Microsoft Word embedded as an OLE document:</p> |
