is it possible to achieve native look and feel with tornadofx ? if yes, how?

Hello, it is possible to collect layout events by logger, for application telemetry, with tornadoFX?

Hi. Is there a more "elegant" way to set the item / itemProperty of a view model manually besided using

itemProperty.value = <item>

?

After building my scene hierarchy with

override val root = borderpane { ... }

, how can I set the focus to a specific widget inside this hierarchy? Currently I have a TreeView and a TextArea somewhere nested inside

root

and when the application starts the TreeView always has the focus. However, I'd like to have the TextArea having the focus.

I have a view, and i have a tcp connection. i want to update the view when receiving data from the connection but without the view ever becoming unresponsive. i thought all i need to do is use a separate thread for the networking stuff, if i try to update the view (specically, adding an element to an observable list) i get an

IllegalStateException: Not on FX application thread

. How do I deal with this? also why does it only happen when the list isn't empty ?

Hi, what should be the conventional way to truncate the empty part of the chart? like below. I tried to play with invalidateRange but it didn't seemed to affect and i'm not sure if there is something simpler. Thanks

java.scene.paint.color

is really annoying to work with. it'd be nice if you could do things like:

val myColor = Color(0.5, 0.5, 0.5)
myColor.saturation += 0.5
myColor.opacity *= 0.3

etc, but nope!

If anyone was considering Qt for cross-platform. There have been some changes. IMO, they've had increasing sales but need a net profit at this point. The last annual report has them at -2.5 million euros (net profit). https://www.qt.io/blog/qt-offering-changes-2020 Seems similar to Oracle but I don't know if there are going to be OpenQt spinoffs

hi, how can I find some document or sample for access SQLite from within TornadoFX? Thanks

Is there a way, short of creating a new

Scope

, to obtain a new instance of a

Wizard

each time? I'm finding it a bit clunky and error-prone to build out the

Wizard

such that it expects a

Scope

with its dependencies graph prepared. Making the `Wizard`'s

scope

know about all the wizard pages dependencies, those pages dependencies' dependencies, and so on is what makes it feel clunky to me. Is there a way

find()

and

inject()

could act as a factory instead of as a singleton lookup? I feel like that would really simplify this. Is that possible?

Hey all, for a personal project I implemented a

SuspendingView

class which allows you to invoke a

suspendingAction { }

block as a coroutine replacement for

asyncAction { }

(i.e. the block gives you a CoroutineScope for invoking suspending functions). It also auto-cancels launched coroutines if the view is undocked. Is this something anyone else would be interested in? If so, what’s the best way to contribute this back to the TornadoFX project? Here’s the current implementation in my project: https://github.com/emanguy/GitlabTimeTracker/blob/master/src/main/kotlin/ui/util/SuspendingView.kt And here’s somewhere I use it to call suspending functions: https://github.com/emanguy/GitlabTimeTracker/blob/master/src/main/kotlin/ui/view/LoginView.kt#L33

Tornadofx contains Lazy loading gridpane, or other component?

Are there any Javafx skins that works for jdk 12+? Was excited to use https://github.com/jfoenixadmin/JFoenix/ but then we saw that it wasnt working for newer java jdks 😞

Is there a way to get TornadoFX to render transparently, so that something like OBS can capture it onto a stream without keying out a color?

this isn't tornadofx, but it's javafx + netty http://bekwam.blogspot.com/2016/03/a-javafx-netty-websocket-client.html

Hi, What would be the best or recommended way for the communication between different ViewModels? Imagine having a text field, a table and a text area. When I enter some name into the text field and press enter, a new file with this name should be created, added to the list, and used by the text area to compose the text, which is automatically saved in the background whenever the user stops typing. Also, when a file is selected in the table its name should be inserted into the text field and the user can edit the file via the text area. Currently I have three ViewModels, one for each component. Table and text area communicate via a shared ViewModel, similar to the example shown in the tornadofx guide. But I'm not sure how to communicate e.g. the creation of a file to the other components. I was also thinking about using the event bus as this is something that I can wrap my head around. Another possibility is to use only a single ViewModel for all views. Any best practice tips for this?

so im using javafx in a mixed java/kotlin project, and im using relative paths for the images. when i use gradlew run, everything shows up as expected, but when i package it into a .jar file, the image doesnt show up. i guess the relative paths get messed up when packaging it into a .jar? im not sure how to fix that

I have a bunch of javafx properties that should be read-only externally. Is this the right way to do that? It seems weird that s is val. I'm wondering if the compiler will wind up caching that val after one fetch.

Hello there, I want to create a view containing (among other things) a progress bar in a GridPane. I don't want this progress bar to shrink in height if the window's height is reduced. I have tried

vGrow = Priority.NEVER

, but that didn't change anything.

class ProgressBarView : View() {

    override val root = gridpane {
        row {
            progressbar {
                gridpaneConstraints {
                    margin = Insets(10.0, 10.0, 5.0, 10.0)
                    useMaxWidth = true
                }
            }
        }
        constraintsForColumn(0).percentWidth = 100.0
    }
}

I guess I could explicitly set the minimum height using

minHeight = some_number

, but I'd like to avoid having to deal with absolute height values. Is there any other way? Thanks in advance 🙂

Hey there, I am working on a chat app, looking for a way to hide empty rows in listview so that if I have only 2 items in a list I see only those and not empty smartcells. Please help. Thanks.

If I have

class MyApp:App(MyView::class)

and later from another window (which has a different scope) I do

find<MyView>().openWindow()?.requestFocus()

, how do I get it to focus the original view instead of creating a new window?

How to make a debounce click with tornadofx, does anyone know?

And if you run into problems of wrong class file version during compilation - delete your .gradle folder to make sure with the next build you'll get the correct version only 🙂

Thanks a ton! Will try ir out tomorrow.

Hello developers I have installed Intelij TornadoFX plugin and created a gradle project then when I run it, the ide only says failed as the screenshot, and when tried to run "gradlew run" in the terminal it runs successfully, what might be the problem. also "gradle scan" doesn't have errors, link: https://scans.gradle.com/s/hps6fjpr6hcdy Project JDK: java 1.8.0_251

I need to force model.valid to false, so I use it in my enableWhen

But in gradle, kotlinOptions, sourceCompatimility and targetCompatibility are set to 11 or more.

For example, how to get from any node to the view it is in, or how to get from a view containing a tabpane to the view contained in the currently selected tab.
