kotlinlang #tornadofx

suffers the same problem as creating a JavaFX dialog directly: The text gets cut off and you can't even resize the alert window to see the truncated message.

Copy code

confirm(
    title = "Delete post?",
    header = "Delete this post?",
    content = "The entire post and all of its attachments will be deleted irrevocably.",
    actionFn = {
        println("DELETING")
    }
)

I'm really losing patience with JavaFX. -.-

Are there other cross-platform UI toolkits I should investigate, or is JavaFX the main game in town?

How do I get text to wrap to the width of the container? I have an HBox that centers a VBox, and the VBox is nicely elastic: It's the full width of the window when the window is small, but expands wider (to a limit) as the window is enlarged. But if I stick a Text with a paragraph of text into that VBox, it overflows and just keeps on going, off-screen, as a single line. I can set a wrapping width, but that ignores the size of the VBox container, which ruins the elastic UI.

Hey everyone, can someone help me to find a nice way to go from one view (MainMenu) to the next view (Workspace). They have different size which makes everything using

mainmenu.replaceWith(workspace, sizeToScenne = true, ...)

kind of ugly, lagy or jumpy... on the other hand creating a new Window with

find<WorkspaceView>().close()

find<MainMenu>().openWindow(escapeClosesWindow = false)

resulted in messing up the scopes (which i didn't cared about at all at that point) and some other stuff... but looks much better. Maybe someone has some thoughts on this ... Thanks

Hi everyone, Any idea why this is happening when I am trying to run TornadoFX application via intellij (with Gradle) but if I am compiling the project into far-jar it's running without any issue.

i made a tornadofx with jdk11 project that worked fine until yesterday, but today: when using jdk8 it highlights all javafx imports as unresolved references when using jdk11 it doesnt highlight anything, but i still get "unresolved reference" compile errors when using jdk13 i get a groovy script error even though i use a kotlinscript instead of groovy for my build.gradle wtf is going on (╯°□°）╯︵ ┻━┻

Copy code

listview(blocks) {
	setCellFactory {
		val cell = ListCell<Block>()
		cell.text = cell.item.toString() //nullref here because cell.item is null
		return@setCellFactory cell
	}
}

how do i get a reference to the item the cell is going to represent so I can set the cell text?

It seems that you're better off having everything you need in the column value so you can use

TableCell.itemProperty()

Have you already tried to do what you want with cellFormat?

I've been using tornadofx with jdk11 using a gradle build and suddenly yesterday it stopped being able to run the app in intellij or with

gradle run

. That seemed like a bug in the javafx gradle plugin -- the error message was because it was running with

--module-path

that had no arguments. I managed to solve it by downloading openjfx 11 and setting

sdk =  'javafx-sdk-11.0.2'

. Now I can build and run the app both directly via gradle and in intellij. HOWEVER, now intellij is red-underlining all javafx references because it can't find the library. How do I tell intellij where to find the javafx library so that I don't get the underlines and code completion starts working again?

Does TornadoFX on Jdk11 work as well as on Jdk8, or are there runtime issues?

Oh good, javafx 14-ea+6 fixes the problem where a single emoji can crash the entire application.

Hey everyone, could someone post a example gradle-build file how to wire a newer jdk 11+, jfx-plugin, tfx and so on. Somehow i cant get it right. Thanks!

If I have a vbox with 2 children, is there a way to force it so the two children each take up 50% of the height?

one thing I've always liked the idea of is dictionaries keyed by type, that return typed values. Coroutines implemented this with coroutine scope, where you can write

coroutineScope[Job]

and the static type of the return expression is

Job

. Similarly the static type of

coroutineScope[Dispatcher]

Dispatcher

. I'm looking at

Node.properties: Map<Object, Object>

and wishing it was something similar to

CoroutineContext

. Ideally I could write something like

myNode.typedProps[ImportantListener]...

Has anybody implemented this?

I have a object in a 3rd party library (e.g.:

Person

) that I am using as the value of an

ItemViewModel

. It has a collection (e.g.:

var hairColors:Set<String>

). How do I bind it to the

ItemViewModel

? If I do

val hairColors = bind(Person::hairColors)

, I get

java.lang.ClassCastException: java.util.LinkedHashSet cannot be cast to javafx.collections.ObservableSet

. I think I need to do something with

bind(forceObjectProperty=true)

and

rebindOnChange

, but I am not sure what.

I cannot really understand why this is the case. I have installed

JDK 13

and

Open JFX

but when I create a tornadofx project using IntelliJ plugin, it keeps failing.

I'm really surprised there is no parameter or method to set the stage title in

App

, nor to provide multiple stage icons. Also why must we provide the entire

Image

instead of the filepath and let the

App

class handle the rest? Also no stage dimensions...

Copy code

class Start : App(
    title = "My App", 
    height = 300.0, width = 600.0,
    primaryView = MainView::class,
    icons = arrayOf("myIconS.png", "myIconM.png", "myIconL.png"),
    stylesheets = arrayOf(MyStyleSheet1::class, MyStyleSheet2::class)
)

Hi. Not directly related to TornadoFX, but there's a Log4j exploit out and you may need to upgrade. https://github.com/advisories/GHSA-2qrg-x229-3v8q

I've gotten rusty on my JavaFX/TornadoFX animation. I'm creating a demo for a symposium I'm speaking at, showing machine learning versus rule-based algorithms with autonomous vehicles. I am creating a VERY simple simulation where a little triangle has three sensor lines sticking out of it, and it's going to follow a path and avoid hitting any walls that touch those sensors. Here is what I have so far: https://github.com/thomasnield/auto-driving-simulation

My simple question is... what is the easiest way to animate it following a path, while rotating so its nose follows the path?

Does someone know how to solve this problem?

Copy code

e: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class tornadofx.UIComponent, unresolved supertypes: javafx.event.EventTarget
    class <http://tornadofx.App|tornadofx.App>, unresolved supertypes: javafx.application.Application

For now I’d prefer to rely on Java 8 (because of some other modules of mine), my current Java configuration is:

Copy code

openjdk version "1.8.0_232"
OpenJDK Runtime Environment (Zulu 8.42.0.23-CA-macosx) (build 1.8.0_232-b18)
OpenJDK 64-Bit Server VM (Zulu 8.42.0.23-CA-macosx) (build 25.232-b18, mixed mode)

Thanks for the suggestions @altavir! I work for the German Aerospace Centre and we to multi-dimensional analysis and optimization for multi-disciplinary aircraft design. Most of us still use Python but I try to show them the light of static typing and still having a nice syntax with kotlin 🙂

Hey everyone, is there some documentation or site where i could lookup how to create something like derived / calculated properties for example a cost value which consist of a multiplication of 3 other properties? Another thing im struggling to find is how i can group together multiple properties and listen when one it changes. I found something like this

Copy code

private val costRecalculationTriggerProperty = SimpleObjectProperty<ObservableList<Property<*>>>(
      FXCollections.observableArrayList { p -> arrayOf<Observable>(p) })
private var costRecalculationTrigger: ObservableList<Property<*>> by costRecalculationTriggerProperty

Is there something else i could use which is kind of more readable?

Dumb question: Does TornadoFx work with OpenJdk 13 & OpenFx 13? I've done a fair bit of tornadofx, but only ever used jdk8 environments.

Does TornadoFX still want to support Java completely? Just interested, because I saw a lot of tiny functions that could be optimized by inlining
