To create a new Task we would code:

Task<String> taskInstance = new Task<String>() {

@Override

protected String call() throws Exception {

// Do something expensive here

Platform.runLater(() -> {

// Code to be executed on main thread goes here

});

return "Done!";

} // End of call

}; // End of new Task()

JavaFX CSS and Stylesheets

The JavaFX controls can be styled using stylesheets. We can load a stylesheet using the

"stylesheets" attribute applied to a container. To use this attribute, we would code:

</stylesheets>

</SomeContainer>

The CSS properties for a control all start with "-fx-" to indicate that they are JavaFX as opposed

to web. The JavaFX CSS reference provides all the details of the properties available. Some of the

more common are:

• -fx-text-fill – The color of the text

JavaFX Deployment

Once an application utilizing JavaFX has been built in Eclipse or some other tool, the next thought

is that of deployment. Deployment is sequence of steps necessary to make the application available

for users to use.

The deployment tools generate three primary artifacts.

• A JAR file – This JAR contains the compiled code and other resources necessary to execute

the application.

• A JNLP file – This file allows the application to be deployed from a Java Web Start

environment.

• An HTML file – This file provides a template to launch the app in a web page.

If we wish to create a Windows "msi" installer, we will need to install the Wix Toolset

(http://wixtoolset.org/).

If we wish to create an EXE installer, we need to install Inno Setup Compiler )

To build a deployable solution we follow three primary steps.

The first is to get our application the way we want it. With this done, we extract all the compiled

classes and resources into its own directory … for example a directory called "bin". Eclipse does

this for us … there is a directory called "bin" next to our "src" folder.

With a directory containing our compiled code and resources, we now use a tool called
