does tornado fx have builders to convert `Property<T>`'s into `Flow<T>`s?

Hi, I am trying to create a UI with TornadoFX but got some trouble in using embedded views with hbox. Maybe I am missing something? Because shows up:

class MasterView : View() {
    override val root = hbox {
        RouteView()
    }
}

class RouteView : View() {
    override val root = vbox {
        label("Routes Folder")
        combobox<String> {

        }
        listview<String> {
        }
        button {
            text = "Check Route"
        }
    }
}

However, if I put the RouteView code directly inside the MasterView hbox it works without problem - or if I use another layout like borderpane/vbox. Does hbox require something special?

I've had many problems with WebView through the years. So much so that I use the commercial JxBrowser instead This problem with Amazon's Java 8 distro is the latest for me https://github.com/corretto/corretto-8/issues/26

Is there any way to show just the calendar that is psrt of datepicker instead of it being a popup of the text component?

Hi everyone, I have an ObservableList with items. I created a CheckBox for each item in the list using Fragment and the ListView. (basically the MVC-tutorial but simplified: ) The functionality works but I don't want to have a list but just a regular vbox. Is it possible to change the ListView to the VBox? What I basically need is a VBox with checkboxes with label based on a MutableList (names don't change) where I can get a list of checked items and a list with unchecked items in a idiomatic way (It's for my thesis...) I know VBox Has a bindChildren, but I don't know at this moment how to use that with the ListCellFragment. or if there is a similar Fragment that has startEdit and commitEdit

@edvin @Ruckus I just created a very very small PR but I see that the build fails on travis while it works on my system

interesting that you are getting that exception, I get the following

Hi @Joe S! You need the VM argument because

DataGrid

depends on an internal API. This will be fixed with JFX 13 as these internal APIs have been made public.

which vm argument

Hi, I'm new to JavaFX and TornadoFX (which I'm trying to use for a small desktop app) so I'm probably missing some basic concept, but I've been looking around for a couple days now and nothing I've tried so far works. Whenever I try running the app it fails with error

Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

From what I understand that seems to be linked to JavaFX missing, but I'm using JDK8 with TornadoFX 1.7.19 I've also tried running a View on its own and it fails with error

Caused by: java.lang.NoSuchMethodError: javafx.stage.Window.getProperties()Ljavafx/collections/ObservableMap;

which looks to me like the same error except more verbose. I am using the Oracle JDK and haven't tried OpenJDK yet.

man, I'm having a ton of trouble with updating a text field. I'm just trying to use tornado for a simple visual part of my app (feeding images to opencv and then showing a histogram along with some text. I just want to continually update that text, I don't care if it's in a viewbox or whatever. Current code is extremely messy, but I really don't care. I do care if I'm following best practices (I tried using Property Bindings, but was unable to get that to work either), but really I just want to get a small dumb app working. https://github.com/snowe2010/opencvtest/blob/master/src/main/kotlin/com/tylerthrailkill/testing/main.kt I've tried following the tornadofx-guide repo, but it's quite confusing, especially for someone that isn't sure what they're actually looking for.

i can't seem to get a DataGrid updated, when the maxCellsInRowProperty changes. it seems I should be able to call private fun updateItems() on DataGrid ...

what is the best ui control to change a SimpleDoubleProberty? (i cannot get a spinner to work without custom code)

what do folks use to deploy/bundle/distribute tornadofx applications? I wanted to distribute a binary for the three major platforms without the users needing to install jre before

we are planning to do a windows app in dec. We thinking to use, tornadofx, javafx, wpf or qt

there is anywhere some documentation where I could see the adv over those tech?

also, is tonadofx working with the java13?

@edvin what other things need to be completed in jdk 10 branch ?

I need to convert some properties that hold poin-values to millimeters/inches or other units, and and allow the user to edit these. Is there by chance any sort of bi-directional binding with a converter in tornadoFX? https://stackoverflow.com/questions/57216415/javafx-bind-number-bidirectional-with-add-multiply (- otherwise i'd just implement this myself)

Hi, I'm trying to find the best way of creating a nullable property in an

ItemViewModel

of a "Java-primitive" type. The only way I figured out how to do this is to wrap it in a

ObjectProperty

, but the

bind {}

function seems to wrap the value in another property:

Property<ObjectProperty<Boolean?>>

The values on the labels are:

nullableStringProperty1 = null
nullableStringProperty2 = null
nullableBooleanProperty1 = null
nullableBooleanProperty2 = false

Is there a cleaner way of dealing with nullable primitive types than

Property<ObjectProperty<Boolean?>>

? Thanks.

Hey everyone 🙂 I made a little TFX application 🌪️! I love having things neat and tidy, so I love having labels everywhere on my stuff: • Around my Desk: • On folders (trying to get rid of these, but) • On my drawes with my Computergear, Cables, Soldering stuff, 3d Printing stuff etc... • In the Kitchen • labels inside my freezer where i have different herbs and some veggies • labels on Tea • labels on Spices I had used inkscape for that task before - but there were several inconveniences that made me not like the workflow anymore: • Slow program start • simply too many features for my simple use case • I used Groups with cloned label-content (there will be labels that i need printed multiple times) - that was a bit cumbersome So I wrote a simple application with the sole purpose to create labels, output a pdf-document that can be printed. It's still very basic, but if any wants to check it out, let me know 😉

Hey all, just getting started with TornadoFX and I found the documentation a little sparse on how to use an

ObservableMap

to populate a

TreeView

and dynamically re-render when the underlying data changes. Any advice?

Hello everyone, I have a controller which stores the data of some workers types. At some point i need this controller to calculate the hourlyRate and I would like to inject this controller. This seems not to be possible because my class is not a tfx component so i used

val workers = find(WorkerDatabase::class)

which works fine if i use it in a function, but not if i declare it as a field in the class (Getting NPE if i use

workers

). Maybe somebody could tell me whether i'm doing something wrong ...

Hey guys, quick layout question -- I have a

TableView

inside an

HBox

with some siblings, inside a

VBox

with some siblings. Can I get the table to both

vgrow

and

hgrow

to fill all available space when the window is resized?

Hi all, I have a simple application that is for walking down a list of Cards. Each card has an image, and I use the "n" shortcut to move to the next card in the view by invoking a method on the controller. The main view only shows the card's main graphic, there's no lists, or other components. I have a controller loading all the cards, and holding a model for the card. When I initialise the controller, i set the model to the first card in the list, and the view is bound to the model. This all works, and I see the image for the first card when it loads. When I press "n" I can see the logging for the controller's function invocation, and it updating the model as follows:

class CardAlignController : Controller() {
    val cards = FXCollections.observableArrayList<CardData>()
    val model = CardDataModel()
    var currentIndex = 0

    init {
        cards.addAll(...) // some loader code here
        model.item = cards[0]
    }

    fun nextCard() {
        model.item = cards[++currentIndex]
        println("Next invoked, index: $currentIndex, currentCard: ${model.card.value.name}")
    }

but the main view doesn't update. How can I tie moving through the list to the main view? I don't have anything to do a bindSelected() on, so I'm not sure how to proceed. Thanks!

Another question on my card rendering application. I have the image updating as per previous thread, but I'm now looking how to scale an imageview based on an observable value. I currently have:

imageview(model.cardUrl) {
                        x = 0.0
                        y = 0.0
                    }.also {
                        // ensure we scale from 0,0
                        val scaleBy = model.scale.value
                        val scale = Scale(scaleBy, scaleBy, 0.0, 0.0)
                        it.transforms.setAll(scale)
                    }

but this is only changing on

model.cardUrl

, and doesn't update when I change the scale value. How can I use the model's scale value so it affects the scale of the drawn image? When I update it, the image doesn't change size. Note: I found I had to use an

also

to scale, as the

scaleX/Y

values in the imageview closure scale from the middle of the image and I couldn't work out how to do it from 0,0

I have a project in mind, and I started using tornadofx - because of kotlin. I have 2 issues. 1. for my App, (stage view or main window) - I am using Borderpane. Initially, it has menubar and logo at the center view. so when I select menu item login/connect, I would like to be able to open a fragment in the center of the border pane and it to be centered. I am not sure how to do that, because when I assign the find(AppView::class).root.center = (fragment::class).root, fragment occupies the whole screen. The plan is that after login, I would fill the left side with table view - data retrieved from DB/Rest 2. Second issue has to do with form button is not leaving space between itself and last textfield in the form. I am attaching images for help. Thank you in advance.

When I run this minimized example code and click the button I get

java.lang.RuntimeException: A bound value cannot be set.

because

x2p

in ThingModel is two-way bound. Is there any way to change the

val x2p = bind(Thing::x2Property)

call to be just a one-way binding? I'm only using it for display purposes -- there's nothing that needs to be written back.

@Douglas KN Have you seen this link? Look for "readonly = true". Unlike in plain JavaFX, bind() is a bi-directional bind by default. (In plain JavaFX you use an explicit bindBidirectionl() for two-way binding) https://github.com/edvin/tornadofx/wiki/Binding
