NetBeans Platform 6.9 Developer's Guide

Overview of this book

<p>The NetBeans Platform has many features provided out of the box for Swing desktop application developers. It can take you hours just to create menu bars, toolbars, a window system, and other typical desktop application infrastructural needs rather than you focusing on your domain knowledge. Imagine how much time you could save with a hands-on guide for using the NetBeans Platform, which relieves you from creating desktop functions for each of your applications.<br /><br />This book guides you through the development of a complete Swing application built on the NetBeans Platform. Each chapter introduces a number of new concepts relating to a theme, such as the window system, and then shows you how to implement the concepts in the application you are creating. At the end of the book you have a task manager, which you can adapt to your own purposes. Or you can, of course, create your own applications, now that you have built up a solid basis of NetBeans Platform knowledge.<br /><br />The NetBeans Platform is a framework for developing large distributed desktop applications. It aims to drastically simplify desktop application development by providing a number of techniques, patterns, and full-blown Swing components out of the box. Most desktop applications have very similar technical requirements, such as: a consistent user interface, extensibility, data display, configuration settings, a help system, distribution mechanisms, on-line update possibilities, and the ability to be deployed to multiple operating systems.<br /><br />Fulfilling these technical requirements over and over again for each new application is expensive, superfluous, and boring. The NetBeans Platform gives developers a transparent, open source, extensible, and free framework that address all of these technical requirements. This book will guide you through all these topics and show you how you can apply the lessons learned in the context of a real application.<br /><br />The central driver of the book is the creation of a complete sample application, chapter by chapter, throughout the length of this book. You will learn how to apply the key concepts in your own work environment, so that you will be able to build flexible, reliable, robust and scalable Swing applications yourself. At the end of the book, you will be comfortable creating similar applications yourself and you will know what to do when you get stuck.</p>

Multiple models in pure Swing


Suppose you want to represent a list of TopLevelTasks in a standard Swing application; you would probably use a JList. If you want to display additional attributes for the Tasks, such as the due dates, you would use a JTable. Finally, if you want to represent the whole hierarchy of TopLevelTasks and subtasks, you would logically use a JTree or a JXTreeTable from the SwingLabs project, if additional properties should be displayed.

Problems arise when you want to change the UI representation after having chosen one of the approaches described above, as each of these Swing components has its own data model. And, unfortunately, each of these data models is incompatible with each of the others. As a result, switching from one visual representation of data to another is difficult and time-consuming because it involves rewriting a lot of plumbing code. In particular, of course, newbies to Swing suffer from this problem, as they need to learn multiple data models at...
