Backbase 4 RIA Development

Overview of this book

Backbase is a very powerful and complex JavaScript library, with many user interface components to help make web development easier. It allows the development of Rich Internet Applications (RIA) that run within all major browsers but its powers and complexity mean that the choice of component can be overwhelming. Understanding when and how to use the right component might not always be straightforward. This book makes that easier. This is a practical book that teaches you how to use the Backbase Client Framework effectively, with a complete overview and many examples. A core developer of the framework puts the technologies used into a wider perspective of existing web standards and a seasoned software architect explains why XML-based UI definition produces better web applications. The transparent use of AJAX technologies, for example to submit forms, or to retrieve updates for data grids, can be taken for granted with the Backbase framework. Packed with examples, the book shows you how to get the most from the library of UI components, and then extend the library with its own custom language. With this book in hand, it is easy to enable AJAX within your web application. You will be able to use the Backbase framework effectively, from basic applications to complex, custom-defined UI components. This book contains a complete overview of all the UI libraries available within the Backbase framework and shows examples for each element described. The Backbase framework offers an innovative Tag Definition Language (TDL), which allows developers to create new UI components that can be used as XML elements, in the same way as using the built-in GUI library. Using TDL brings considerable development advantages, and this book explains how. Significant attention is also given to architectural aspects of designing a web-application, showing sample applications using a model-view-controller approach.

An integration example

We are going to discuss an example of integrating a data grid widget as it is offered by the Ext JS framework, into the Backbase framework.

We have a dual purpose for this:

  • Firstly, it will give you a feel for what it is like to program using a framework that employs JavaScript exclusively

  • Secondly, we show that it is fairly easy to incorporate functionality that is offered by another framework or library, if for some reason you prefer that over what is offered by Backbase or if it offers something additional

In the next chapter, we will show another integration example, using Google maps in our C3D sample application.

To start, we are going to display a data grid with XML data. In this case, the data is a list of trips from our sample application, using the Backbase framework. We have seen this example before in Chapter 5, therefore, please look back to see the contents of XML file we will use. For clarity, we show the code for the dataGrid here:

<b:dataGrid width...
