And then there were more than 50: More Swing Component Libraries

Posted by hansmuller on October 14, 2004 at 1:13 PM PDT

Swing Component Depot

column has a backlog of
more than 50 component suites. They'll all appear there eventually
however we thought you'd like to see the queue now, in all its
unadorned glory. So, here for your delectation is a brief summary of
all 50+ of them.

I appreciated the comments in response to the original version of this
blog ("Another 40 Swing Component Libraries")

that have appeared here on and on,

particularly the many suggestions about libraries that deserved to be
added to the list. Some of the feedback pointed out that it wasn't
entirely clear where I was drawing the line, not every library listed
here was a Swing Component suite. I have to admit that didn't religously
hew to that line. Looking at web sites devoted to Swing component
suites often lead to products that were relevant to Swing app
developers like spell checkers, PDF generators, and so on. A few of
these have made it into the list because I couldn't help but
inadvertantly vacuum them up in the process of collecting vital
statistics about mainline Swing component libraries. In this update I've added
another 14 libraries to the list, nearly all of the ones suggested by
people who've offered feedback:

  • jProductivity - Components!
  • UICompiler
  • Einnovations EII Commons
  • Gandalf Wizard Framework
  • Zeus Components Library
  • JBalloonTooltip
  • Hypergraph
  • JForm
  • Foxtrot
  • Kiwi
  • Geosoft G
  • StarLink
  • Inxight Software
  • Thinkmap

One suggestion that led to to a few extra entries that probably don't,
strictly speaking, belong was Hypergraph. Hypergraph is an impressive
open source project that has produced a J2SE component for visualizing
hyperbolic trees. There are several commercial projects in this




All of these products provide applet viewers for hyperbolic trees and
all of them have eye-popping demos on their respective web sites (go
ahead and look, you will not be disappointed). Both Inxight and
Thinkmap provide SDKs, however based on my cursory look at their sites,
the SDKs are for server side work or they're custom JDK1.1 viewers
based on AWT. In fact I didn't list at all, despite the
inspiring name, since there didn't appear to be a Java SDK there at
all. Still it didn't seem right not mention them since they're
great examples of what desktop Java is capable of and they could
probably become part of a modern Swing application. Plus, the
Hypergraph site provided pointers to all of them and I just couldn't
stop myself.

in many cases I've lifted or crudely paraphrased vendor product
descriptions in the list below, rather than craft my own pithy
summary. It's not because I'm incapable of doing a good job of that,
it's because I'm lazy and life is short. It's also worth pointing out
that I'm not trying promote the relative merits of these packages,
just their existence.

There are more than 50 entries in the list below and that's more than the
most devoted fan of Swing component libraries is going to want to sift
through. I've attempted to break the entries into categories to ease
the burden a bit: General Purpose, Database, Graphs and Charts,
Special Purpose (for physics, astronomy, oil exploration, etc,
components look here first), Calendars, and "More". Naturally not
every library fits nicely into one of these categories, for example
nearly every general purpose library contains calendar or database
parts. The "More" category contains libraries that didn't fit into a
category. There are two (obvious) additional categories that are
missing because they're big enough to deserve their own roll-up:
layout managers and look and feels. Those categories will have to
wait until a future blog; I've got blisters on my fingers.

General Purpose

JASE Software - ConfigureJ

A Java Swing library for creating configurable menus, toolbars and
popups. Applications built with Configure can be reconfigured by
end-users through direct manipulation of the GUI itself.


JAPISoft provides everything from

an XML Editor and XSLT Debugger, to most of the components you'd need
to build a software engineering tool, like an IDE. Among the Swing
parts you'll find on the site are


a Swing component/framework for editing XML/XHTML documents,


a Swing framework for MDI applications that is compatible with standard layout
managers, and


a generalization of JFileChooser.
Most of the software is vailable for free evaluation and the sites,


are packed with screenshots.

Infragistics - JSuite

JSuite is a broad suite of Swing and AWT components, including charts

    that supports JavaScript, applets, and SSL. It implements a
    proprietary plug-in interface to integrate third-party and custom
    content handlers (such as JMF, XSL/XSLT, SVG, and PDF).
  • ICEreader SDK enables developers to render static HTML/XML content in
    applications where secure or dynamic Web capabilities are not
  • ICEpdf SDK can be used as a standalone PDF document viewer
    application, an embeddable PDF viewer component, or combined with
    ICEbrowser SDK for a complete web-content rendering solution.

Javaio - WebWindow, Component Suite, JModeler

Loads of very high level parts here, beginning with the WebWindow
browser component. WebWindow is a small pure Java HTML viewer that's
intended to take up the slack from Swing's JEditorPane. JModeler is a

Javaio Component Suite includes components like JOutlookBar (this sort
of thing is sometimes called an "accordion" control), JHelpView for
JavaHelp, and JSlidePanel for animating panels in and out of view.
