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.

Handling user input


As a platform designed to build rich user interface applications, JavaFX provides many ways for users to interact with your applications. In order to implement user interactions in your applications, at a minimum, you will have to capture key presses on the keyboard and gestures from pointing devices. This recipe shows you how to capture keyboard and mouse events.

Getting ready

When a key from the keyboard is pressed or a mouse event occurs, the JavaFX application framework will generate input events information stored in instances of KeyEvent and MouseEvent respectively. These classes are found in the package javafx.scene.input.

Input events are sent to nodes attached to your scene graph. Therefore, in order to receive input events, you must have at least one node added to your scene. Review the recipe Building a JavaFX application for background information on how to do that.
