- The Mac Developer Network
- Steve Scott of Late Night Cocoa has started a new podcast targeted specifically at Macintosh Developers. One of the first episodes on this podcast is a roundtable of developers with several very well known developers starting with Daniel Jalkut, Uli Kusterer and Fraser Spiers along with myself.
- Once more unto the [Beta Cycle], dear friends, once more
- Today marks the first semi-public release of iWeb Buddy, a new application that I have been developing for the past few months. Unlike seSales or applications developed as a consultant, this development cycle has been a blur of activity.
- Apple -- You Did Me A Disservice
- Today is the day that most Mac users have been looking forward to for over a year. Ever since Steve Jobs got up on stage last August and showed us Leopard for the first time. Ever since that first peak almost all Mac users and I dare say ALL Mac developers have been looking forward to this release. Unfortunately, today is also a day that Mac developers are going to be scrambling like rats on a burning ship. This is because Apple decide to thumb their nose at us.
- Further development of Bullfrog 2 for OS X
- Things are starting to speed up on the development of Bullfrog 2 previously mentioned here. In our continuing disclosure about the development process, Jon Trainer has written a very informative article on how the actors are configured.
- Starting over is hard to do
- I mentioned before that I am working with Jon Trainer of Outer Level to write Bullfrog 2 for OS X. This development effort will be targeted at the as of yet unreleased OS X 10.5 Leopard. We also promised to blog about the development as it moved forward. Unfortunately not everything has been roses.

Java Swing's JTable is easily one of the most powerful, customizable, and difficult pieces of the entire API. With the exception of JTree, no other object within the API can be used in so many ways.
There is a problem with this versatility, however. The JTable design is fairly complex, and (in an effort to make using it easier) Sun added several defaults to add users new to the API. Unfortunately, these defaults are commonly overused and incorrectly implemented. In this article, I will outline the creation of a custom table model and how it can help avoid duplication of data and creation of unmaintainable workarounds.
If all you ever need a JTable for is to display data in a tabular fashion, this article is not for you. However, if you have ever used the DefaultTableModel and either found it wanting or found yourself writing horribly unmaintainable code to manipulate the data or retrieve the data, read on-the answer is fairly simple.
The Data
In this article, you will implement a custom table model that stores data and gives an easy way to access and modify that data. First, let's define the data we want to display. This example has a large number of widgets, and each widget is its own object.
The class Widget is a very simple data object that adheres to the JavaBean standard. The next trick is to be able to view these widgets inside a JTable and to easily access and manipulate the widgets that are displayed in that table without a large amount of casting or complexity.
