QR Code ISO/IEC18004 Maker In Java
Using Barcode generator for Java Control to generate, create Quick Response Code image in Java applications.
On lines 14, it reports progress by calling the updateProgress() function Progress is again reported on line 44 On line 32, it calls the setCustomers() function to pass the JavaCustomer objects created from the CUSTOMERS table to the FetchCustomersTask class

Using Barcode printer for Java Control to generate, create bar code image in Java applications.
In all three cases, the desired action is simply to write a value to a variable in the JavaFX class However, this is not possible for two reasons:
Barcode Scanner In Java
Using Barcode recognizer for Java Control to read, scan read, scan image in Java applications.
JavaFX variables can be read and written only from the main thread, and this code is not running in the main thread There is no officially supported way for Java code to directly access a JavaFX variableThis is because the way in which JavaFX variables are represented in compiled class files is currently a detail known only to the compiler and the runtimeThe only way to read or write JavaFX variables from Java is by calling a getter or setter function in the JavaFX class that can do the job for youThis is why the setReturnValue() and setProgress() functions were included in the FetchCustomersTask class
Denso QR Bar Code Generation In Visual C#.NET
Using Barcode creation for .NET Control to generate, create QR Code 2d barcode image in Visual Studio .NET applications.
To update the state of the FetchCustomersTask class, the updateProgress() function must call the setProgress() function of the FetchCustomersTask class, but it cannot do so directly because the call must occur in the application s main threadTo do this, it uses the deferAction() function of the javafxlangFX classThis is the same function that was introduced in 12, Platform APIs, and which is used to execute a JavaFX function at some future point on the main application thread Here, we are calling it from a Java class on a different thread Because Java does not have the concept of function point-

ers, we cannot directly pass a reference to the setProgress() function Instead, we have to use the following construct:

FXdeferAction(new Function0() { @Override public Void invoke() { tasksetProgress(progress, progressMax); return null; } }); Function0 is a class that allows a function with no arguments to be calledThe code that does must be placed in the invoke() method, which is overridden in this example to call the setProgress() function of the FetchCustomersTask object It might at first seem that implementing an asynchronous task is quite a complex undertaking, but in reality it is simpler than it looks Much of the discussion in this section has been around how and why the work should be divided between the task itself and the class that contains the code that is to be run in the background, and we have spent a lot of time looking at the details In practice, if you need to create your own asynchronous task, you can do so by taking the example in this section as a template, removing all the code that is specific to database access, and replacing it with your own code In future releases of JavaFX, it is likely that support will be added to make it easier for the Java code that runs in the background thread to communicate with the JavaFX class, which would make it possible to simplify or remove much of the code that appears in this example

and other devices If you have been building the example source code for this book in either the NetBeans or Eclipse integrated development environments (IDEs), you have already been packaging JavaFX code, because both IDEs use the javafxpackager tool that comes with the JavaFX software development kit (SDK) to compile the source code before running it Given this fact, you might be wondering why there needs to be a chapter dedicated to packaging and deployment in this bookThere are several reasons for this chapter to exist:
Code 39 Drawer In Java
Using Barcode creation for Java Control to generate, create Code 39 image in Java applications.
To show you how to use javafxpackager as a command-line utilityThis is useful for a couple of reasons First, although it is convenient (and usually faster) to develop using an IDE, production builds are typically done from a batch script, which means using javafxpackager Second, there are some very useful things that you can do with javafxpackager that the JavaFX NetBeans and Eclipse plug-ins don t currently let you do from within the IDE Although javafxpackager creates the files that you need to place your packaged application or applet on a web server, those files may need to be tailored to suit your deployment environmentWe ll take a look at all the files that javafxpackager creates and show you how they can be customized When you run your JavaFX code as a stand-alone application from within the IDE, it is run with all available privileges and so has full access to your system and to the network However, when your application is deployed, this might not be the case In the course of this chapter, you ll see some of the restrictions that apply by default and how you can arrange for your application to be given the additional privileges that it needs to do its job

Because this chapter is based around a command-line tool, there are no IDE projects for the example source code Instead, you will find the source code that you need in several subdirectories below the deployment directory of the book s example source
