if i could even get intelliJ to flag something like

resourceBundle.get("MizzspelledKey")

with "this lookup is suspicious" would be a step forward

How do you guys do when using collections of FX controls, like ControlsFX, with TornadoFX? Do you write all the builders or just go with

apply

blocks and

add

?

Switching to Compose will be a pleasure just for leaving the FX layout system behind. I used a dozen GUI toolkits in my life and never had so much pain.

Are there any good alternatives for kotlin desktop application dev?

@Samkeene: JavaFX. Depending on your needs, JavaFX may be, all things considered, just as good as TornadoFX: you may miss a few things, but you would also not deal with a major component that is not actively developed and whose design is flawed and dated in many regards. Software ecosystems are in constant evolution, and not being developed and updated is a huge problem. I started FX development with TornadoFX, and I had to learn how JavaFX does things and then also how TornadoFX does the same thing, just for saving a few keystrokes here and there. Probably it's the kind of software I'm writing. I don't care about most of the extra features of TornadoFX, because they are obsoleted or geared towards line-of-business applications. So-called "creative" applications often are not well served by "standard" toolkits, to be honest. For example, "editing information" in my application is kinf of particular and looks very different from the "editing model" of TornadoFX (why the author used the name ViewModel for what is an "edit model" is beyond my comprehension). I'm also writing an application which is the desktop version of a mobile-first application, so I'm influenced by that for many reasons and less likely to adhere to the assumptions at the base of TornadoFX. My point is that, being TornadoFX not developed anymore and with no signs of any kind of plans for the complete redesign that it needs in order to fit its possible niche, in 2020, learning TornadoFX may be not worth the effort. Cognitive effort is a price. Stockholm syndrome may happen when you spend very much effort learning a piece of software.

Is this really the way to center an image in ImageView? https://stackoverflow.com/questions/32781362/centering-an-image-in-an-imageview/32866286#32866286

In order to say something positive and constructive about TornadoFX, since I criticized it several times here, I want to mention that IMHO a new version of TornadoFX should separate the "builder DSL" from the other components. The DSL should be generate as much as possible via metaprogramming, and not by hand. The team working on this DSL should cooperate with the JavaFX team in order to synchronize the releases and possibly evolve the JavaFX API to make the metaprogramming easier (even if just by annotating the classes and the methods). Annotating the JavaFX API where necessary for making metaprogramming the DSL effective would lay the basis for libraries of JavaFX controls to using the same annotations and get the DSL for free. The other features should be moved in other modules (as it was already planned somehow). Some of the features, like serialization and networking via HTTP, should be removed and replaced by the equivalent "standard" libraries in the Kotlin ecosystem. And coroutines. With "should" here I mean that in my opinion these are the minimal set of changes required to make the project maintainable and appealing to as much of the the Kotlin developer audience as possible, so that it can make any sense and possibly gain some kind of financial support. It's very hard for just one developer to guide TornadoFX through this evolution through the years. This is probably why TornadoFX went from being innovative to being covered by a certain layer of dust. Not because the author is not good. This is not a personal attack. A project like this requires more than one pair of hands and more than one head.

Hello Tornadoers. Does anyone have an idea regarding following in TornadoFX? If there are multiple instances of the same Fragment, but with different state and data, is it possible to have different instances of the Controller for each of those Fragments?

Trial and error 🙂 The

vbox

class has a method named getChildList() which returns a mutable list of the element in the vbox. You can remove and add to this lists using

removeAt(i)

and

add (i, NewContent)

. In your case

i

is likely to be 1, but you may have to experiment a bit. Print out the contents of the different element as you're testing to figure out exactly what you need to modify.

Um... hi 🙂 Really new to Java/Kotlin, and asking for help implementing my first serious application. It's a connector that interfaces GPS reports (and some other things) from digital radios into a really legacy and clunky mapping software (OziExplorer, anyone? dammit... its API is horrendous!) Now for the TornadoFX question: how should I implement a UI item that would change its caption depending on an external Boolean fun? Seems like I'd still need to bind this to a property and somehow tell TFX to refresh it?

Hello, I have a question regarded to TabPane component. I have the "Main" View, which is divided into two Views, "Menu" View and "Content" View. I have TabPane in "Main" View, and I want to add a new tab from "Menu" View. I believe that this is possible, but I am quite new to TornadoFX, and I cannot find the solution. I would be grateful if someone can help me with this. :)

Hi i want to build a schematics system based on pipes, my question is how can I build composed objects like a t using basic shapes like a rectangle to be create the pieces

Hello friends, is it possible to implement a debounce action on the button click?

Hello there. Can anyone help me understand how I should handle errors in tornadofx? How does event filtering work?

Hey everyone, is there any possible way to run a tornadofx compiled application on a device with java 14? It doesn't have javafx bundled anymore so would I have to require my clients to install java 8? Alternatively, is there perhaps some way to bundle openjfx in my application as an alternative to work with tornadofx?

Hi all Someone ever saw issue like this in text?

Is there a better way to do read only properties?

private val isRunningWrapperProperty = ReadOnlyBooleanWrapper(false)
    var isRunning by isRunningWrapperProperty
        private set
    fun isRunningProperty(): ReadOnlyBooleanProperty = isRunningWrapperProperty.readOnlyProperty

Hello, I was wondering if there's something sort of like a style guide for building GUIs using TornadoFX? I know what I want to do, and even have some idea of how to do it, but are there things I should be leaning towards like dependency injection, or fragment use, etc? The best example I can find is in the TornadoFX documentation: "but using  inject()  delegates is the most idiomatic means to perform dependency injection and has the advantage of lazy loading." That's great, now I know to use inject() over find() where possible. Are there other idiomatic things about TornadoFX that I need to know besides what's in the documentation, and if so, do you have any suggestions as to where I should look for this information?

hi, I'm contemplating getting back into TornadoFX but I'm confused about TornadoFX 2 . Is that ready for prime time ? If so can somebody share a link to what's needed to setup an Intellij TornadoFX 2 project . Also, does the Intellij TornadoFX plugin support TornadoFX 2 . thanks

If there’d be interest in this idea, please do let me know. TornadoFX is abandoned but I’m starting to look around for a new project, and I have a fondness for JavaFX - ultimately, despite its neglect, the base engineering was very good. Jetpack Compose doesn’t quite seem right to me, partly because it’s a mobile toolkit (not so great for building complex database backed enterprise apps with lots of forms and charts), and partly because the whole attempt to make GUI “functional” seems wrong - a GUI is at heart mutable state. It’s the way the user mutates the state of your app. Trying to make something fundamentally mutable look and feel immutable seems like a square peg/round hole problem.

Heyho, quick and hopefully simple question: I have an observable list as my model. I want to paint a circle for each item in the list and refresh (add circles) when there are new Items in the list. Is there a way to achieve this with some kind of "fake control" where I bind the list? Or do I need to add my own change listener to the list and update the UI? Thanks!

@Samkeene just a late thank you, Sam, for your template from way back September. I had only one tweak to get it running on my side: IntelliJ wasn't using the 15 jdk to run Gradle. I did make a couple of minor changes afterwards, but they're about my testing preferences. Had I done it myself it would have taken hours and been garbage. Yours took me 15 minutes and and I actually understand it. So. Big props! Folks, if you want openJdk 15 and openjfx 15 and tornadofx 2, this is a nice tight gradle template. https://github.com/SKeeneCode/TornadoFX-Template

Hey! Not really a TornadoFX question, but JavaFX one 🙂 When a

TableView

is made editable, every mouse double click / mouse single click on a selected cell / [Enter] press starts cell edit. This is pretty annoying, is there an easy way to disable it? I have a dedicated button in the UI to trigger cell edit.

hey guys im having a nightmare getting scenicview running on java 13, has anybody run it with something after java 11? how did you do it?

Hey, how would I go about displaying a very big amount of text? Minimum 200k lines.

Also, how do I export to a Windows Application? I heard you could do it with LauncherFX, but I couldn't figure it out.

How to discard objects at the end of a screen, I'm having a memory problem?

I love tornadofx but it's been in limbo for a while now. There have been numerous discussions on github and here overtime about the project needing new maintainers. Aleksander here perfectly states the problem: "I think that many people are eager to contribute to this repository, but the work to be done is undefined". Jacek here has created a gradle tornadofx2 which many of people have asked for (and IMO should replace the maven version). Edvin has repeatedly indicated he is open to letting others maintain. Would people here be willing to throw their hat in the ring and sit down and discuss the direction of the project, and potentially take on various degrees of responsibility with regards to the project? If we can get a handful of people we could perhaps take some first steps. Please reply to this thread if you would be interested!

noob question: how do I tell a textfield to react to the Enter key being pressed?
