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.

Windows and dialogs

Windows and dialogs can display content that is disconnected from the main browser window. Unlike a JavaScript pop-up window where in fact a completely new browser window is created, the Backbase framework window and dialog widgets stay on top of the browser window and cannot be moved outside.

The window widget is a draggable, resizable container that fully supports maximize, minimize, restore, and close functionality. When used in combination with the windowArea and taskBar, the user can seamlessly navigate between multiple windows as easily as when using a standard desktop application.

The modal dialog is most commonly used to present (or request) important information to (from) the user while preventing interaction with the rest of the page or application.


The window widget represents a resizable window that floats above your application. It can be closed by clicking on the closeButton widget in the top right of the header.
