Applications are encouraged to batch up multiple operations into fewer runLater calls. Otherwise, the application may become unresponsive. NOTE: applications should avoid flooding JavaFX with too many pending Runnables. And it will get uglier if the logic is more complex.Īnd then there's this nice note in the nLater method's documentation: Ok, there're few things here and the most important one is that since Runnable returns void, we need to process results "the old fashioned way".

The code to execute this task is fairly simple (ignore the Result class for now, it's just a simple POJO):Įnter fullscreen mode Exit fullscreen mode And if time is higher than 500 ms it will mark it as slow. This list will show the name of the task and time taken to execute it (up to 1s) in order of execution. List view of results from these long running tasks.
SelectBox), which would perform some background tasks whenever user selects different value To illustrate this I created a simple application with just two components: The UI is lagging when operations are performed and you get the impression you are doing something wrong. Everything works, technically, but sometimes it does not feel right. You define your layout, create first components, start adding behavior to them and you expect results. Let's say you're writing simple UI in JavaFx. I think there are a lot of benefits there, but this is not the topic for today. we had an utility that connected through ssh and executed a script, whose results were displayed in the UI). Also, these kind of applications are perfect for communicating with filesystem or underlying OS (e.g. If you don't have internet connection, you cannot access the site (if it is not offline-enabled). First of all some users still prefer it to web-based services. Why on Earth would anyone want to build desktop applications in 2020 anyway? But JavaFx was like a fresh breeze and version 2.0 introduced concept of FXML files, which allowed you to define the looks and style of your components in similar fashion as HTML and CSS. I was firstly introduced to JavaFx in 2013, when it was still part of JDK and it was a proper replacement for Swing, the former UI library, that was. Why on Earth am I writing about technology for creating desktop applications in Java in 2020? Since it was open-sourced and separated from JDK it has become the only reasonable choice for building desktop apps in Java. But believe it or not it's alive and kickin'. On the other hand, if you thought JavaFx project is long dead, well. If you never heard of JavaFx before don't feel bad.

If you are developing Android or any other apps that "compute and render content" at the same time read on! In this article, I would like to show you the benefits of RxJava in practical example - desktop JavaFx GUI application.
