GroovyFX is an API that makes working with JavaFX in Groovy much simpler and more natural to those well-versed in Groovy. GroovyFX is focused on leveraging the Builder pattern for JavaFX applications, but more than that, it leverages some of the DSL capabilities that Groovy provides and makes the Groovy based JavaFX code easier to write and, just as important, easier to read. For example, JavaFX colors can be set using pseudo variables, like red or blue.
The primary goal of GroovyFX is to make JavaFX development simpler and more concise than what it takes in Java. This is done via numerous built-in features that Groovy provides, including the Tree Structured Language supported through Groovy’s Builder framework that makes declaring a JavaFX SceneGraph more closely resemble the actual SceneGraph itself. This is done through GroovyFX’s SceneGraphBuilder object, that supports all the Controls, Shapes, Effects, and other JavaFX objects, as well as support for using Groovy closures for event handling.
Features include a SceneGraphBuilder, a TimelineBuilder and Groovy DSL features to handle JavaFX objects, enumerations, binding, and paints/colors.
The following screenshots show two GroovyFX applications, one demonstrating the visual effect features available with JavaFX and the other demonstrating the JavaFX Charts. The ChartDemo.groovy source is listed below the screen snapshots.
