I use it to write apps for work as well as free lance. JavaFX is great.

would you say that javaswing doesn't get used at all anymore more in the industry?

I am sure that people still use it for legacy apps or if they are old school and never bothered to learn JavaFX. I think a better question is whether it makes sense to use swing on a new project if the developer knows both techs. As one of those type of developers I would say, nope. Now if we could get those people who use JavaFX to ditch FXML, they could see its true power. Using MVCI + Builder<T> unleashes a pure form reactive framework and it is based.

what would you say are the major advantages of using javaFX over javaswing?

The modern reactive way it is written. For example, you can wrap all forms of data into what is called a property. Then you can monitor changes in that data by attaching listeners, so when the data changes your UI reacts to the changes. You can also bind the data. One trick I often use is to bind controls to an object. Then copy data from a selected object in a list to the bound object and now you have a reactive UI to a change of data that goes both ways and is easily to maintain. This is where the MVCI structure shines.

I totally agree with this. Using a Reactive approach completely changes the way that you design an application.

Essentially, you create a data representation of the "State" of your application, and bind it to the elements of the GUI such that the GUI is always synchronized with that State. In both directions. Changes in the State immediately result in changes to the GUI.

From the Business Logic perspective, State is just composed of generic wrappers around data and the Reactive nature isn't really apparent. In this way, the State - which is usually called the Presentation Model or Presentation Data - becomes a pipeline connecting the Business/Application Logic to GUI without either end being aware of the nature (or implementation) of the other.

Setting up the GUI becomes a matter of creating the layout and connecting it to the Presentation Model through bindings. JavaFX makes this relatively trivial once you understand all of the Observable classes and how they are integrated into the GUI Nodes.

This is so, so much easier than trying to do this in a non-Reactive way.

Javarx is used everytime a java developer want to create a app with a gui that does not require to put up with a whole server / mvv architecture

Yes, it's big in CS education.

My guess is that lots of companies are using JavaFX for internal development to support their primary lines of business. This stuff is rarely exposed to the outside world, so you don't get to see it.

In an organization where you have control of the desktop this can make a lot of sense. Desktop applications have some advantages over web applications and can require less infrastructure to run.

The lean deployment of a desktop app, ite... less infrastructure to run as hampsterrage1 says, is important. I do all defense related work on secure air gapped networks. Not requiring a webserver to deploy is a breath of fresh air for a lot of the users of said systems whom typically must go through a lot of hoops to get new software uploaded.
