JGo

A graphical component that allows developers to quickly build graphical applications

JGo for Java follows the successful design of the MFC GO++ library, but is written completely in Java. It was designed for the Java 2 platform and the popular Java development environments.

JGo(TM) is a graphics library that makes it easy to build custom interactive diagrams, network or workflow editors, connected graphs, scheduling or organizational charts, smart maps, flowcharts, and software design tools. It has built-in support for many shapes, text, images, containers, connectors, orthogonal links, arrowheads, scrolling, zooming, selection, drag-and-drop, resizing, in-place text editing, tooltips, layers, and multi-page printing. It is powerful and efficient, yet small and easy to learn and use. It includes built-in support for Swing's Undo framework.

Not only does JGo make it easy to build applications and applets with graphical editing capability, but it also makes it easy to to provide such functionality in Web applications with very thin clients by putting the graph image generation and editing on the server as servlets.

JGo supports Java 2, Java 2D, and Swing.

Why use JGo?

Use JGo when a graphical display of objects, showing their states and relationships, would allow your users to visualize and manipulate their business data in a more appealing and intuitive way than with lists and tables.

You can easily add data-aware JGo views to your existing applications without modifying your underlying designs. The well-designed, flexible, and extensible Java2 based framework is based on many years experience with our GO++ product.

JGo comes with full source code but no runtime fees. JGo will save you time and make you money by making your product better, faster.

JGo is written entirely in the Java(TM) language.

Major Features

  • support for Swing undo/redo
  • option to allow views to show objects at negative coordinates
  • greeking of JGoText and JGoPort at small scales, sensitive to printing
  • DefaultBase property for JGoImages, for convenience when loading images in Applets
  • resizing a link to connect it to a new port now modifies the existing link
  • example code for reading and writing XML files for Flower processes
  • new GeneralNode example classes, with varying numbers of labeled ports
  • new JPEGView example class, to demonstrate producing JPEG images from documents
  • example servlet using JPEGView to produce images for web servers
  • new Overview example class in Demo1, allowing navigation of another view
  • improvements to the Flower editor sample

Additional Features

JGo has full support for the Java 2 platform:

  • Swing based views
  • Java2D features such as thick and dotted line pens
  • drag-and-drop support between components
  • tooltips for JGo objects
  • scaling views (zooming in and out)
  • orthogonal links
  • printing framework
  • good documentation
  • many performance optimizations, in both time and space
  • several useful example applications
  • support for JComponents as JGoControls
  • control over JGoGridView grid appearance and behavior
  • view events and listeners (to be notified of selection changes or double-clicks)
  • documents, selections and objects are Serializable
  • documents and selections are Transferable
  • support for automatic layout, available as a separate add-on product
  • layers of objects within documents
  • support for Linux
  • a "modifiable" property for documents and layers, for easy "read-only-ness"
  • various improvements to strokes / links / labeledlinks
  • built-in ability to allow users to copy as well as move within a view
  • a JGo.jar file is included, so that you don't have to build it yourself


Platforms:
  • JBuilder 3
  • Visual Cafe 4
  • JDK/SDK-SE 1.2 and 1.2.1 and 1.2.2 and 1.3.0
