JHotDraw 7.1
2008-03

Substantial changes have been made to fix shortcomings and bugs in the frameworks.

Please take a look at the JDiff for a detailed report of all changes between JHotDraw 7.0.9 and 7.1.

Drawing Framework:

• Most Figure methods with prefix basic… have been removed. These methods were used to support Undo/Redo by the Figure objects. In JHotDraw 7.1, this burden has been delegated to the Tool objects.
• The class structure has been modified to gain more flexibility. Most notably, the Drawing interface extends now from the CompositeFigure interface.

Application Framework:

• The experimental application framework based on JSR-296 has been removed, because it is not mature enough yet, to keep JHotDraw in sync with it.
• The Project interface has been renamed to View, to be more in line with the upcoming Swing application framework JSR-296.

Samples:

• SVG: The background colors of SVG drawings can be set now. A number of bugs related to reading and writing gradients has been fixed. There is no support for editing gradients yet.
• ODG: This sample is not functional yet. It consists only of a few skeleton classes.

JHotDraw 7.0.9
2007-06-21

• Redesigned Undo/Redo handling for Figure attributes.
• Made many incompatible changes in all packages in order to pave the way for SVG support.
• Rewrote the SVG sample application.
• Enhanced the Draw package to make support for transformations on Figures possible, in order to be able to support SVG.
• Added Batik gradient classes, in order to be able to support SVG.
• Added new package org.jhotdraw.application based on JSR-296 "appframework" version 0.42. This package will replace org.jhotdraw.app in future versions.

JHotDraw 7.0.8
2007-01-10

• Streamlined interface names and class names to make it easier to learn the framework.
• InputFormat/OutputFormat interfaces and default implementations added to drawing framework.
• ImageHolderFigure interface and ImageFigure default implementation added to drawing framework.
• Enhanced SVG sample application.
• Removed NanoXML-Lite library.
• All code is now compilable with J2SE6. The minimum platform requirements for JHotDraw 7 remains J2SE5.

JHotDraw 7.0.7
2006-11-12

• Reorganized file structure.
• Fixed NetBeans project files and Ant build scripts.
• Fixed guide.

JHotDraw 7.0.6
2006-08-27

• Renamed PlasmaDraw to JHotDraw 7.
• Changed copyright notices in all source files.

JHotDraw 7.0.5
2006-07-30

• Moved all packages from ch.randelshofer to org.jhotdraw.
• Reimplemented the 'Net' and 'Pert' sample applications.
• Implemented an 'SVG' sample application.
• Fixed minor issues here and there.
• Added a tweaked version fo NanoXML back into the framework. The tweaked version of NanoXML allows to read XML documents which have a DTD, without opening a network connection to the DTD document and thus improving performance when opening a XML document.
  Once we figure out, how can use the javax.xml API in a more performant way, we might throw out NanoXML again.

JHotDraw 7.0.4_1
2006-06-26

• Removed copyright notice of NanoXML and JGoodies Looks from Draw Application and Draw Applet.

JHotDraw 7.0.4
2006-06-25

• Reorganized package structure.
• Added support for type safe Figure attributes.
• Replaced the application framework with a new one.
• Added support for double strokes.
• Added support for line positions: centered, inside, outside.
• Added more sample figures.
• Replaced MS Office style icons by a new open source icon set.
• Removed dependency to NanoXML library.
• Removed dependency to JGoodies Looks library.

JHotDraw 7.0.3
2006-01-29

• Added support for Bézier paths and replaced all legacy Polygon code with it.
• Cleaned up the framework. CompositeFigure does not implement FigureListener anymore.
• Moved layout strategy for ConnectionFigure into a separate class named Liner. Added a SlantedLiner. ElbowLiner not yet implemented.
• Migrated from Java 1.4 to 1.5. The framework uses now type save collections.

 

JHotDraw 7.0.2
2006-01-18

• Revived the project. Replaced integer coordinate system by a double precision coordinate system.

 

JHotDraw 7.0.1
2004-03-01

• Finished adaptation from JHotDraw 5.4b1. JHotDraw 7's framework is based now entirely on Java idioms. It makes use of Java2D, Swing Undo/Redo, XML. The user interface is now very close to MS Office 2002.
