My team is short on time in implementing a simple shape editor. We have to be able to create, delete, move, and copy simple shapes like rectangles and lines. This has to be a stand-alone application (may not use applets). We've fully implemented our model underpinning the application, as well as the controllers. Any advice?
Edit: This is part of a much larger application. Just missing the presentation element, to clarify.
If you're just wanting to display graphics, check out the Java2D library.
Here is the API: http://download-llnw.oracle.com/javase/1.4.2/docs/guide/2d/spec.html There are also many many tutorials: (here is one) http://download.oracle.com/javase/tutorial/2d/index.html
Just try Googling Java 2D examples or some similar query.
I think you'll find it's actually pretty easy to draw 2D shape in Java :)
I had been using JHotDraw, a figure editor in my own application. You may refer to their source code. They are using design pattern quite extensively.
It is a not too bad figure editor, and it is originated by Erich Gamma, one of the author of classic design pattern.
JHotDraw is a two-dimensional graphics framework for structured drawing editors that is written in Java. It is based on Erich Gamma's JHotDraw, which is copyright 1996, 1997 by IFA Informatik and Erich Gamma.
