JavaFX 1.2 Application Development Cookbook

By: Vladimir Vivien

Overview of this book

JavaFX Script enables you to easily create rich Internet applications by embedding multimedia components. Although you can create stylish Internet applications by modifying these default components, even advanced users find it challenging to create impressive feature-rich Internet applications with JavaFX. Also, there are limited JavaFX components to work with and by default these components don't look visually appealing.This book explores limitless possibilities to style your application by coding JavaFX components to display your content in a more appealing fashion. The recipes in this book will help you to create customized JavaFX components with which you can make modern, feature-rich applications.First, you will be introduced to the JavaFX SDK and other development tools available to help you be productive during development. You will create an application in JavaFX by arranging complex graphical components (and non-graphical libraries) with simplified declarative constructs. You will then explore the fun side of JavaFX by using transformation techniques to manipulate the location and dimensions of objects. The next chapter is about the GUI components that are available in the framework, which provide a high level of interactivity. You will learn how to use the media component to play media content. Then we will access data and manipulate data locally or remotely. You will explore many deployment options and integration tips and tricks to take advantage of runtime contexts. Finally, you will interact with pure Java code to read and write files in JavaFX and to establish interactions with computing platforms.

Accessing remote data with HttpRequest


All modern rich client platforms provide ways to communicate with external servers. The Web and its associated protocols have become de facto technologies for building client-server applications. This recipe shows how to use JavaFX to communicate with web servers over HTTP using the HttpRequest object from JavaFX's IO API. You will learn how to submit a request to a remote web server and use HttpRequest's event-driven callback functions to handle responses from the server.

Getting ready

Prior to getting started with HttpRequest, you should have an understanding of the basic mechanics behind the Web and its HTTP protocol (see the HTTP reference at the end of this recipe). JavaFX's HttpRequest class, located in the javafx.io.http package, provides ways to manage communication between your JavaFX client application and a remote web server. To illustrate the use of the HttpRequest class, we will use it to pull down information from Wikipedia's entry...
