There's a few things to do before we dive into the tutorial itself. For example, to do Eclipse programming, you will have to get your hands on an Eclipse installation first. Read through the following sections to get ready for the tutorial tasks.

Required Software

For this tutorial, we need you to have Eclipse installed:

1. Install Eclipse. For what we do, we recommend installing the Eclipse Modeling Tools.
2. Install the KIELER KGraph Editing and Visualization feature
   
   1. Go to Help > Install New Software
   2. Use either of our nightly update site at http://rtsys.informatik.uni-kiel.de/~kieler/updatesite/nightly/ or one of the releases.
   3. Check the following items and press next.
      1. KIELER Layout - KIELER KGraph Editing and Visualization
      2. KIELER Sources - KIELER KGraph Editing and Visualization (Source)
      3. KIELER Sources - KIELER Layout API (Source)

Finding Documentation

During the tutorial, we will cover each topic only briefly, so it is always a good idea to find more information online. Here's some more resources that will prove helpful:

• Java Platform, Standard Edition 6 API Specification
  As Java programmers, you will already know this one, but it's so important and helpful that it's worth repeating. The API documentation contains just about everything you need to know about the API provided by Java6.
• Eclipse Help System
  Eclipse comes with its own help system that contains a wealth of information. You will be spending most of your time in the Platform Plug-in Developer Guide, which contains the following three important sections:
  
  • Programmer's Guide
    When you encounter a new topic, such as SWT or JFace, the Programmer's Guide often contains helpful articles to give you a first overview. Recommended reading.
  • References -> API Reference
    One of the two most important parts of the Eclipse Help System, the API Reference contains the Javadoc documentation of all Eclipse framework classes. Extremely helpful.
  • References -> Extension Points Reference
    The other of the two most important parts of the Eclipse Help System, the Extension Point Reference lists all extension points of the Eclipse framework along with information about what they are and how to use them. Also extremely helpful.
• Eclipsepedia
  The official Eclipse Wiki. Contains a wealth of information on Eclipse programming.
• Eclipse Resources
  Provides forums, tutorials, articles, presentations, etc. on Eclipse and Eclipse-related topics.

You will find that despite of all of these resources Eclipse is still not as well commented and documented as we'd like it to be. Finding out how stuff works in the world of Eclipse can thus sometimes be a challenge. However, this does not only apply to you, but also to many people who are conveniently connected by something called The Internet. It should go without saying that if all else fails, Google often turns up great tutorials or solutions to problems you may run into. And if it doesn't, Miro and I will be happy to help you as well.

As far as KIML and layout algorithms are concerned, you can always refer to our Wiki which has a section about KIML and the KIELER layout projects. The documentation is not complete, however, so feel free to ask Miro or Christoph Daniel for help if you have questions that the documentation fails to answer.
