    Is 
    loadFXML()
    a custom method?

    Aha, my bad. I have always used 
    fxml()

    Copy code
    import javafx.scene.layout.HBox
import tornadofx.App
import tornadofx.View

class MyApp:App(MyView::class)

class MyView: View() {
    override val root = loadFXML<HBox>("dummy.fxml")
}

    Something like this with your fxml just works!

    @hestad Can you drive your stream-reading off of an interval timer? If you have a loop, say in a Task which is a good practice, but that loop calls a runLater() in each iteration, you may be stacking up a bunch of pending Runnables. This might look like you're burning through the loop, but nothing is getting updated. This is because runLater()'s semantics just say that the Runnable will be called later in the order in which their enqueued. This might mean finishing the feed from the http stream and then updating the UI all at once.

    @hestad i'm not sure what the application, but say you were moving game pieces around by an http feed coming from a peer-to-peer setup. You could animate the pieces from current position to the changed position as reported by your http stream.

    Another option is to buffer the work. Create a JavaFX Task, return a structured object, then in the succeeded() method ( ui() in TornadoFX ), do your UI update. Avoid creating lots of Threads such as one per stream read.

    ^ try javafx.concurrent.ScheduledService rather than the Java SE timer for the interval. Use a data structure like "HTTPStreamResult" to return the messages coming from the stream to form a class ScheduledService<HTTPStreamResult>

    @abhinay we are able to see the fxml and the buttons, however the button variables are null

    @carlw Your example is fitting enough. And I could run it on an interval timer. Currently I do it in a single spawned thread. Our problem wasn't a slow consumer, but more that our sortedlist got out of sync with the observable list (where the data changed). If we get a slow consumer problem, we could also add a queue and throw messages.

    is the http stream always open?

    the key difference in what I'm suggesting is to push the completed work at the end of the call() and into the succeeded(). This is instead of putting everything in the call() with a loop calling Platform.runLater().

    @edvin 
    workspace.headingContainer.removeFromParent()
    doesn't seem to be working -- where should one call this method from? (I've been trying 
    init
    and 
    onDock
    of my workspace subclass.

    Ah, I see there's a property now 
    showHeadingLabel = false

    @Niranjan Shah You need to add a listener to the 
    valueProperty()
    - https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/ComboBoxBase.html#valueProperty--

    I also tried binding the buttons with their fx:id and it seems to work. Check out the snippet below:
    Copy code
    import com.jfoenix.controls.JFXButton
import javafx.scene.layout.HBox
import tornadofx.App
import tornadofx.View

class MyApp:App(MyView::class)

class MyView: View() {
    override val root = loadFXML<HBox>("dummy.fxml")
    val cbList: JFXButton by fxid()

    init {
        cbList.setOnAction { print("Button Pressed") }
    }
}

    @abhinay for fxml kindly put the cbList in other fxml and include it in the fxml which is you using in View class

    @abhinay the objects are not found (they are visible, however val cbList: JFXButton by fxid() is null) when the objects are in the included file

    @carlw I agree that, by calling runLater N times/second, if a new thread is spawned per call (a single-thread thread pool would be preferable), is the wrong mechanism in my case. Have you any experience using the EventBus?
