Griffon Mythbusthers

I’ve seen myths surrounding the Griffon framework appear over the years, I think it’s time to set the record straight and dispel any misinformation. Myth: Griffon projects require Gradle as a build tool. Incorrect. The preferred choice for building Griffon projects is Gradle if you happen to use a Lazybones template to bootstrap the project, however you may use Apache Maven, Apache Ant, or any other JVM build tool (even Make if you really want to) to build a Griffon project. Myth: Griffon projects can only be bootstrapped with Lazybones. Incorrect. The preferred choice for bootstrapping a Griffon project is Read More

Creating aggregate JavaFX bindings

The standard JavaFX API provides a class named Bindings that can be used to create all kinds of bindings your application may need. Methods in this class can be used to translate any Observable, ObservableValue, Binding, Expression, and/or Property into another Binding, regardless of their original type. Here’s for example how you could translate a StringProperty into an IntegerBinding, by exposing the length of the contained String: StringBinding sourceBinding = … // initialized elsewhere IntegerBinding lengthBinding = Bindings.createIntegerBinding( () -> sourceBinding.get().length(), sourceBinding); While quick and to the point we’re forced to read the value directly from the inputs (in this Read More

Happy 9th Birthday Griffon!

Today marks the 9th anniversary of Danno’s announcement of Griffon 0.0. It’s been quite the ride since then, and lots of fun if I may say so. As Danno noted, Griffon began life as a fork of the Grails codebase at the time. He literally copied the Grails source, removed everything that was related to HTTP and Servlets and added Swing on top. This allowed Griffon to bootstrap itself very quickly and begin its own journey. The feedback we’ve got was very positive and we happily continued adding more features, letting Griffon to have it’s own identity. Plugin support was Read More

Writing JavaFX applications with Kotlin

Hi there! Today I’ll like to show you how Kotlin can be used to write a JavaFX application. This particular example encompasses both runtime and buildtime aspects as I’ll also show how Gradle Kotlin Script can be used to build the project. Let’s get started! UPDATE: The code assumes you’re using Oracle JDK8 which includes JavaFX (jfxrt.jar) by default. Make sure you have a compatible JavaFX binary if you’re using a different JDK release, such as OpenJDK. You can install OpenJFX on Ubuntu by invoking sudo apt-get install openjfx for example. Update 2: You may encounter problems when attempting to Read More
