The Java Developer's Guide to Eclipse

This example plug-in is discussed in Chapter 21, Action Contributions: The Integration Fast Track. Also see project com.ibm.jdg2e.actions that contains examples that are not dependent on the Eclipse IDE. It is helpful to have these projects installed and available in your Eclipse workspace when you read this chapter. To study these examples you will need to examine both the Java code and the plug-in manifest file.

Running the Example

To run this example, install the project com.ibm.jdg2e.actions.ide in your workspace and launch the run-time instance of Eclipse (Run > Run As > Eclipse Application).

There are three actions available. Depending on the specific action, they may appear in the Workbench menu bar or toolbar, a view's menu or toolbar, or as a context menu (pop-up menu) in a view or editor. Here are the instructions for running each action.

1. Close Unmodified Files Action
   This action closes all editors for files that have no modifications to be saved. It is available from the Workbench File pulldown menu, a context menu in the Navigator view, or by entering the key combination: Shift + F4.

   

   

2. Show Modified Action
   This action filters the Navigator view to show only modified files, their parent folders, and hosting project. The action is available on the view toolbar and menu. It is a toggle type action. When toggled off the Navigator view shows all workspace content.

   

3. Text Editor Wordcount Action
   This editor action counts the words in the selected text of a text editor and displays the result in a simple dialog. It appears on the Workbench toolbar () or in the context menu of the active text editor when text is selected (see figures below). It is enabled when you select text. The context menu label is: JDG2E: Word Count.
