ObjectDraw Library

1. Using the Library

How you use the ObjectDraw library depends on what IDE you have. There are instructions for setting up your IDE in the first lesson, Getting Started with Java. There are several different versions of the library that you can download, depending on whether you want a version that includes the source and/or the javadoc:

objectdraw.jar
objectdrawWithSource.jar
objectdrawWithJavadoc.jar
objectdrawWithSourceAndJavadoc.jar

2. Reference

There are a huge number of things you can do with the objectdraw library. These pages will help you to figure out all the possibilities, with examples of code using the various features of the library, and compact summaries of the various methods you can use. The pages present the most commonly used features of a class first, but also contain information on how to do more complex things with it.

Objects you can create, but which don't appear on the screen:
Visible objects that you can create:
- Shared Shape Methods
- Rectangular Shapes (ovals, rects, rounded rects, arcs)
- VisibleImage
- Line and AngLine
- Text
- Turtle
Other classes you need to use:
Essential techniques in physics and coordinate geometry

3. Javadoc

"Javadoc" is a system for writing detailed documentation on all the classes involved in a program, and all the methods and variables that belong to those classes. Reading through javadoc documentation will often be your first step when trying to figure out how to do some new thing with a Java library or project. You can access the javadoc for ObjectDraw here:

ObjectDraw Javadoc

If you will be using this javadoc often, it might make sense to download one of the jar files that contains the javadoc. You can also download the javadoc separately:
