JHotDraw 7 is a two-dimensional graphics framework
for structured drawing editors. It can be used to create many different editors
from a simple doodle program up to full fledged diagram editors and vector
animation tools.
JHotDraw 7 is a major rewrite of earlier versions
of JHotDraw which
in turn is a derivation of HotDraw.
Here is a demo use of the framework, a SVG
drawing applet:
Features
- All contracts in the JHotDraw 7 framework are implemented against Java
Interfaces. The framework provides many points to hook in your own code.
- The framework is small enough to create Java applets with it.
- Abstract and Default implementations are provided to get you a quick
start.
- The framework makes use of common Java idioms, such as the JavaBeans
setter and getter methods. This is supposed to reduce your learning
curve.
- The drawing code takes advantage of Java2D. It uses double precision
coordinates for all drawings.
- A drawing can be shown and edited in multiple windows with different
scale factors.
- Undo/Redo is implemented based on the Swing undo package.
- Cut, Copy and Paste clipboard operations are supported.
- XML is used as the default external storage format and for clipboard
operations.
Requirements
- JHotDraw 7 requires a J2SE 6 compliant Java Virtual Machine.
