how to create and control a modular ui with javafx?
For example, if I wanted to display 200 collapsible TitledPanes, with each one holding a TextFlow, TextArea, and a BarChart. It would be tedious having to create 200 sets of identical items in the fxml file and then give each its own unique fx:id. I was searching for info about doing this programmatically and saw there is a tag called fx:include, but I can't find out much about it, not sure if it is really for this purpose.
After I learn more about creating and managing the UI I would like to try making a multi threaded program which can efficiently do searching and sorting of large amounts of data. Having a ui such as this with lots of displays for the data will be useful to see if it's working correctly. Are there any special considerations for creating a thread-safe ui?
I need an EventHandler for my controls, but...
Should I use a single handler for every control in the program? (1 handler)
One for each type of control? (3 handlers)
One per set of controls? (200 handlers)
One per control instance? (600 handlers)
Which way will give the best performance in a busy multi-threaded program?
I could make a class containing each set of controls, and assign the handler to them in its constructor, then track their references with a list. Is there a better way?
Components are what you're talking about with the include tag. The way you that is simply to put <fx:include source="yourfxmlfile.fxml" /> at the location you want the component to be placed at.
If you needs some more clearafication you always can look up The program I'm working on on github.
Hopes this helps a bit

If you have, it may be that your environment variables aren't set correctly.

Well, I don't know Spring Boot -- the last time I used Spring was about five years ago. Maybe someone from the Spring forum can help.

That's just crazy...
The topic is still about making an efficient modular ui and more importantly, how to control it. I'm not sure yet if fx:included components can be individually controlled or if they all will share a single fx:id. My goal is to avoid as much code repetition as possible and have a high performance and professionally done control scheme for a multi-threaded app. Any and all suggestions or approaches to it are appreciated, as well as example programs with source.
Also, if you're not already, use SceneBuilder to modified and visualise your FXML files. In the Java 9 version, under the File menu, is a submenu called Include. That should be a help.

So I had seen on a blog someone saying it doesn't work for that reason, and is only suited for non-interactive panels and such. But now I found someone that seems to be saying it does work by using a trick, over at stack overflow
I will have to try it out and see what happens, will be pretty cool if it works!
in the pane you want to display your content.
This is a example of my homepage:
You see I include my menu and my footer
S Fox wrote:Yep I do use scenebuilder (w/ java8 right now) and I know it has the include submenu, but I wasn't sure if it would work for controllable components as they each need their own fx:id. Including 50 buttons with the same fx:id, that's not gonna work.

You can't use 50 buttons with the same id in the same controller...
That would be the same as having 2 variables with the same name in the same class.
With include, you can't eather, every button would have a different controller.
This said, I don't see why they would have a id, since you can specify your methods in your fxml
In the next example I did 10 times, I didn't care about positioning and so fourth, but you'll get the idea.
main.fxml:
Titlepane.fxml:
![[Thumbnail for main.png]](/t/688132/a/8926/main.png "Filename: main.png
Description: main including titlepane 10x")

Hmm, I don't understand what you mean by specify my methods in fxml.
I thought fx:id was required for each item otherwise how are they referenced later or assigned to the controller?
In your example here with 10 panels, how are each of the 10 bar charts being individually controlled?
It looks like they are all being controlled by fxml.Main so it is one controller, not 10 controllers?
It's all very confusing to me =)
