JFXMobile – first attempt

Who would not like to be able to write a single code base for desktop and mobile? I know I want to, and the applet I’m using for time registration is getting into a pinch with all the browsers dropping support for applets, so why not give JavaFX a try? And see if things go as smoothly as Gluon’s tweets make it sound?

So, first things first and setup a nice virtual machine for this project with Java and Eclipse, hookup the old 1st gen Nexus 7, then download the HelloWorld demo project from Gluon. Finally a “gradlew androidInstall” should do the trick… Continue reading “JFXMobile – first attempt”

Java 8 method references

Java 8 is finally out officially and it brings probably the biggest change to the Java platform ever; lambda’s. Lambda’s are a very powerful technology which will have major influence on the way API’s in Java will be written, but the first critical sounds also are heard already.

Lambda’s in Java have two main aspects; one is the powerful stream API, where all kinds of processing is chained and in that way multicore processing is easily made possible. The other aspect is the replacement of the anonymous inner classes scaffolding, and that is probably the thing people are exited about first, when discovering lambda’s in Java 8. Let’s take a peek using my latest hobby project as an example.

In the previous blog I’ve written about CircularPane; a way to layout nodes in JavaFX in a circle. Below is an example of how some tests in CircularPane look (the green circles are debugging hints):


One of the latest additions is that nodes can be animated into their positions. The example below shows that the left two CircularPanes animate their nodes into place “over the arc”, the right two “from origin”.
