By: Dr Alex Blewitt

Overview of this book

<p>As a highly extensible platform, Eclipse is used by everyone from independent software developers to NASA. Key to this is Eclipse’s plug-in ecosystem, which allows applications to be developed in a modular architecture and extended through its use of plug-ins and features.<br /><br />"Eclipse 4 Plug-in Development by Example Beginner's Guide" takes the reader through the full journey of plug-in development, starting with an introduction to Eclipse plug-ins, continued through packaging and culminating in automated testing and deployment. The example code provides simple snippets which can be developed and extended to get you going quickly.</p> <p>This book covers basics of plug-in development, creating user interfaces with both SWT and JFace, and interacting with the user and execution of long-running tasks in the background.</p> <p>Example-based tasks such as creating and working with preferences and advanced tasks such as well as working with Eclipse’s files and resources. A specific chapter on the differences between Eclipse 3.x and Eclipse 4.x presents a detailed view of the changes needed by applications and plug-ins upgrading to the new model. Finally, the book concludes on how to package plug-ins into update sites, and build and test them automatically.</p>

These different types of editor include BooleanFieldEditor , ColorFieldEditor , ScaleFieldEditor , FileFieldEditor , DirectoryFieldEditor , PathEditor , and RadioGroupFieldEditor . Add a sample of each of these types to the ClockPreferencePage page to find out what they can store. Perform the following steps:

  1. Open the createFieldEditors() method of the ClockPreferencePage and add the following code at the bottom of the method:

    addField(new BooleanFieldEditor("tick","Boolean value",getFieldEditorParent()));
    addField(new ColorFieldEditor("colour", "Favourite colour",getFieldEditorParent()));
    addField(new ScaleFieldEditor("scale", "Scale",getFieldEditorParent(), 0, 360, 10, 90));
     addField(new FileFieldEditor("file", "Pick a file",getFieldEditorParent()));
    addField(new DirectoryFieldEditor("dir", "Pick a directory",getFieldEditorParent()));
    addField(new PathEditor("path","Path...
