that may be due to the fact that I use a tiling WM…

Hi all, is this the best approach to "center crop" an image into imageView??

imageview(productViewModel.image) {
                    imageProperty().addListener { _, _, image ->
                        val newMeasure = image.width
                        val x = (image.width - newMeasure) / 2
                        val y = (image.height - newMeasure) / 2

                        val croppedPortion = Rectangle2D(x, y, newMeasure, newMeasure)
                        viewport = croppedPortion
                        fitWidth = 300.0
                        fitHeight = 300.0
                        isSmooth = true
                    }
                }

@Ruckus in the other kotlin groups, have you seen anyone using Optional to provide an object shell around an empty values?

How could I get a converter for the selectionModelProperty() of a combobox? the same way textfield does it?

Yay, making some progress on porting my collection of kubed demos over to a TornadoFX-based "showcase" application rather than a bunch of standalone apps!

@Carlton Whitehead so controlsfx adds autocompletion to textentries too?

i'll look at ktor when i write a tornadoFX client for the above post

I have an issue with a ViewModel. I have this in it:

var journal = bind(forceObjectProperty = true) { citation?.observable(Citation::journal_id) as Property<Int>? }
    var journalEntry = bind {
            legacyController.journalList?.getElement(journal.value).toProperty()
    }

It is used to feed a combobox, but the problem is even before that I can see it when I do:

model.journalEntry.onChange { println("Changed the journal to $it") }

The model is defined as a

class CitationModel(var citation: Citation?) : ViewModel() { … }

The model is by default a

val model = CitationModel(null)

Once the user loads something, I do a

citationView.model.rebind {
                                citation = newCitation
                            }

where newCitation is coming from some database query. I get the right call to rebind, and the object bound is the good one.

Anyone know of a

Parent

impl that will scale it's content to fit?

I tried to consolidate my classes into an example to post here. Could anyone explain to me how to use a ViewModel & bindings to update the value of

changeableName

in this example when I hit the "save" button in

RenameFragmentTest

? I must learn!

I think "A Master/Detail example" in the "Scopes" section of the Guide shows you how to do this.

If the view is blank, try downloading it

It'd be a neat feature to allow other it to point at other people's accounts and pull in their gists too but then for sure I'd have to start dealing with SecurityManager and all that, bleh

Since your audience is developers, you can ask them to run $ javaws http://www.example.com/mydemo.jnlp

Hi everyone, I'm unable to fix a compilation problem on the TableSelectView article (https://edvin.town/leveraging-tornadofx-to-the-fullest/) All calls to

column(...)

below cause this error:

None of the following functions can be called with the arguments supplied.

override val root = vbox(10.0) {
        tableview(items) {
            column("SKU", Item::sku) 
            column("Item", Item::descr)
            column("Price", Item::price)
            column("Taxable", Item::taxable)
            bindSelected(mySelectedItem)
            setPrefSize(667.0, 376.0)
            columnResizePolicy = CONSTRAINED_RESIZE_POLICY
            vgrow = Priority.ALWAYS
        }

@hudsonb you're right. the wrap() isn't needed. I updated my gist accordingly (and pulled it out of the client's code too)

if its a single file.. with multiples you may have to include multiples.. which is currently only possible using kotlin-dev

How do I get the application name in the MacOS menu bar to be something other than "java"?

hey guys, quick question! so i'm creating a card that looks like the image attached. I'm having problems trying to add the white blur/background effect that the text

chapter 01

sits on top of. i've tried using box-shadow's and blooms but not to the desired result yet. any idea how I would be able to achieve this? I'd appreciate a nudge in the right direction. thanks

Hi, how can a view access command-line arguments? I know the application can via

parameters.unnamed.firstOrNull()

for instance, but how can a view access its enclosing Application ?

@elifarley take a look at the end of this article https://courses.bekwam.net/public_tutorials/bkcourse_tornadofx_mdi.html

I'm using https://github.com/beryx-gist/badass-jlink-example-kotlin-tornadofx to create a TornadoFX app with an embedded JVM so that users don't have to have one installed on their systems. My app needs a web view, and even though the example project compiles fine as is, once I add the

javafx.web

module to

module-info.java

, I get an error:

gradle jlinkZip

> Task :discoverMainScriptsExtensions
e: Module javafx.web cannot be found in the module graph

hi newbie here, this most simplest of code snippets doesn’t work:

import tornadofx.View
import tornadofx.button
import tornadofx.label

/**
 * Created by charles  on 2019-01-18.
 */
class MyView: View() {

    override val root: vbox {
        button("Press me")
        label("Waiting")
    }

}

IDEA claims it can’t find vbox I’m on jdk1.8.0_131 here’s my gradle build

plugins {
    id "org.jetbrains.kotlin.jvm" version "1.3.11"
}

group 'polyglotric'
version '1.0-SNAPSHOT'

apply plugin: 'kotlin'
apply plugin: 'application'

mainClassName = 'com.polyglotric.MyApp'

dependencies {
    compile 'org.jetbrains.kotlin:kotlin-stdlib'
    compile 'org.jetbrains.kotlin:kotlin-stdlib-jdk8'
    compile group: 'no.tornado', name: 'tornadofx', version: '1.7.18'
}
repositories {
    mavenCentral()
}

task wrapper(type: Wrapper) {
    gradleVersion = '4.2.1'
}

compileKotlin {
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

thanks for the help

try compile "no.tornado:tornadofx:1.7.18"

I also just upgraded to the latest version of IDEA , just in case that was of any impact , still same issues

Hey guys, I am struggling with some Problems with css in FX. I use the rowExtender on a table view and give it a whitish background. When selecting the entry in the table and opening the expander I did not find a way to change the text color of the label (see following GIF). Any Idea? Thanks!
