    yeah thats what I did, now I need to find a way to trigger code in the tab when it is programmatically selected

    Maybe the controller could expose the observablelist directly? Right now you're making copies.

    @ron 
    whenSelected {}

    thats on the tab itself right?

    Or maybe I didn't add that to Tab, let me check.

    Ah, yes I did. And yes, on the tab itself.

    If you also need to react to when the selection is lost, you can do an 
    onChange
    on the 
    selectedProperty()
    .

    the whenSelected works, now I need to figure out how to get the listview in that tab to react to it 😉

    Copy code
    controller.tabPane = tabpane {
            tab<CategoryTabView> { tabClosingPolicy = UNAVAILABLE }
            tab<WhatsNewTabView> { tabClosingPolicy = UNAVAILABLE }
            tab<AuthorTabView> {
                tabClosingPolicy = UNAVAILABLE
                whenSelected {
                    println("author selected")
                    fire(MainController.AuthorSelected)
                }
            }
        }

    in the listview of the authors:
  • r

    ron

    12/08/2017, 10:00 AM
    Copy code
    init {
        println("reading authors")
        runAsync {
            readAllAuthors()
        } ui {
            root.items = it
            controller.authorlist = it
        }
        subscribe<MainController.AuthorSelected> {
            root.selectionModel.select(controller.authorModel.item)
            root.scrollTo(controller.authorModel.item)
        }
    }

    I think I will move the runAsync to program start and indeed have the list stored in the controller

    I am writing some unit tests with testfx. Is there a way to block the UI thread while I am doing some work in my test and only then free up the ui thread? I would like to check that some events have not yet been processed on the ui thread

    I am currently using "toolkit.enterNestedEventLoop". But hoping for a "better" way? Any extension methods I should look for?

    @jschneider I think we have 
    runAndWait

    Not what I am looking for. I will stay with enterNestedEventLoop for the time.

    @edvin is the different behaviour of 
    runAsyncWithProgress
    deliberate when the action is not inside the codeblock of the button?

    @ron Absolutely, it’s an extension function on EventTarget, so it will overlay whatever Node you call it on.

    Hi all. I’m thinking about implementing my ZenGuitar3D in Kotlin/TornadoFX https://github.com/JavaFXpert/ZenGuitar3D

    Any guidance for how to approach this, and features to leverage?

    Here’s a brief demo of some of its functionality:

    @edvin so now that I am home, I have more time to respond to the "it feels off" remark. first of, the syntax 
    button("text").action{....}
    seems to be the preferred way of doing a button. (this used to be not the case and the 
    button("text") { action{.....}}
    was normally used.) If you do this new way with the button in a vbox / hbox / form (not in a buttonbar as in my example) it will throw a nullpointer exception:
    Copy code

    @javafxpert Oh, cool! That looks like a pretty specialized UI, so you might not get all the benefits of more traditional UI building in TornadoFX, but there are plenty of extension functions in the framework even for such use cases, and in combination with Kotlin's syntax and features I'm pretty sure the code will be much more readable and maintainable than in plain JavaFX. Will have a look at your app as soon as I have time to see if I can give some more concrete pointers.

    @javafxpert I wrote something similar when I was starting w. JavaFX…mine is a little brute force with bass guitar samples. http://www.bekwam.com/sb/
