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.

Using the Slider control to input numeric values


We have seen how to capture data input using traditional GUI controls such as TextBoxes and Buttons. The Slider control offers a different means of inputting data by sliding a knob along a groove. In this recipe, we use the Slider control to create a color picker application.

Getting ready

The Slider control is part of the standard GUI controls offered by JavaFX in the javafx.scene.control package. By sliding the slider along its track, users are both inputting data by selecting the slider's position on the track, and they are getting visual feedback confirming their input. If you have not used the JavaFX controls, it may be helpful to review the recipe Creating a form with JavaFX controls for some background information.

How to do it...

The following code snippet shows you how to use the Slider control as an input controller to update the color values of another object on the stage. You can get the full code listing from ch04/source-code...
