kotlinlang #tornadofx

There is a a registered primary stage call here and the only component here is a form. I suppose this makes sense, but it makes me curious, does this mean that when you call

FxToolkit.registerPrimaryStage( )

, do we do this to basically have a listener for the existence of components on the stage? I suppose using the

FxToolkit

is the JavaFX way of testing - does this mean that when you initialize TornadoFX `View`/`Fragment`, it is implied that there is a stage?

As I am a professional .NET developer, I'm wondering if JavaFX is still actively used in the industry? It seems nice (especially TornadoFX with Kotlin), but Java in general is not my main thing

@elifarley you can add to your table

onUserSelect(1) { *action* }

where the parameter is how many times a row is clicked

Copy code

class Test: ApplicationTest() {

    override fun start(stage: Stage?) {
        setInScope(CatScheduleModel(), CatScheduleScope())
        val sceneRoot = Editor().root
        addAllIdsToDescendents(sceneRoot)
        stage?.scene = Scene(sceneRoot, 100.0, 100.0)
        stage?.show()
    }
    .....
    @Test fun testTextfield() {
        val textfield = lookup("#beep") as TextField
        verifyThat("#beep", hasText(textfield.text))
    }
}

@Carlton Whitehead update: I added

primaryStage.show()

after adding the ids to the view!! Forgot this necessary step. I'm now getting a new error message:

Copy code

IllegalStateException: Not on FX application thread; currentThread = main

@Czar welcome to the TornadoFX community! As a general rule I gave myself, if I think we could learn together on the channel I keep it to the main thread. I totally agree that threads and their lack of features make it hard to segment conversations on here. I'm not as familiar with

by di()

- can you provide an example?

by inject

is how we easily do dependency injection with models/views/controllers in TornadoFX

amanda.hinchman-dominguez

01/22/2019, 9:27 PM

both are for dependency injection.

inject()

is for singleton components (

Models()

Views()

Controllers()

) which is TornadoFX specific. For

di()

, you can inject third party resources by creating an

FX.dicontainer

Hello, a question. Does anyone know a way after a button was clicked to automatically reset the view to its initial state? Thanks for answers

Hello, does anyone have any examples with TornadoFX, Hibernate and ViewModel?

I add a CSS class "note" to only some Labels in a TreeTableCell. CSS

cell { note { backgroundColor += Color.RED } }

works as expected (only coloring those labels).

cell { and(selected) { backgroundColor += Color.RED } }

works as expected (coloring everything in the selected row).

cell { and(selected) { note { backgroundColor += Color.RED } } }

has no effect. I expected it to color only the labels with the "note" class in the selected row.

I need to open the default web browser from a context menu action, so I call

hostServices.showDocument("<https://google.com/>")

, but it always gives me this error:

Has anyone used Cucumber and TestFX with their TornadoFX app? I have it working when the app is rendered on-screen during testing, but it breaks if I try to run the tests headless with Monocle.

It's having a type inference failure on the

item

from what I can gather from the error because menu items extend Object not Node, I believe.

@bjonnh That depends if you need to manipulate different data types etc. That approach is very generic and is mainly for displaying data. If you have a set of different column layouts I still recommend hard coding them, or at least add some data to the datasets so you can configure the correct type of column/editor if needed.

maybe elsewhere because it is not tornado related

1. Excellent 🙂 Good to know for this evening when I start working on having multiple views with switching. 2. That is ok, just thought I'd check, trying to keep the code as clean as possible as I go, so I don't have to circle back as much.

@alex Most DI takes place at object instantiation time. When you instantiate an object with dependencies, those dependencies are instantiated (and so on). This is called wiring up an app in Spring and Guice parlance. This means forgoing the new operator and using the container in the entry point for your program. There's also the option of delaying the dependency injection. This can be done by interacting with the container as the program is running. You might delay injection because of performance via lazy loading. You might also do this to break cycles whereby two objects reference each other. One object can use the normal means of DI where as the other object (up to you which is which) must call though the container at a later date. As a user, this should all be taken care of behind the scenes and your program starts with each component able to execute in the proper context. For something like an EJB, this means with all the datasources and JMS queue connections to do its work. On a UI, this might mean a shared EventBus. So, besides a few annotations (-at-Inject) and a little interaction with the container (getBean(), injector.get()), you shouldn't have to do any clean up or worry about byte code generation.

@edvin a resizable squeezebox would be great. How hard would that be to implement that?

Shan

02/01/2019, 6:20 AM

I need to get the width of the

LabeledText

inside of the TitledPane somehow

Shan

02/01/2019, 6:38 AM

I actually just came up with a solution to my issue from yesterday that wasn't suggested anywhere and works great! I made a separate

BorderPane

that contains a

label

with my TitledPane's title, and a separate

hbox

for the icon and the menu. I then bound its prefWidthProperty like this:

prefWidthProperty().bind(this@apply.widthProperty().subtract(Styles.smallishPadding.value*2))

which binds its width to the SqueezeBox's width minus the padding I have added. Then I simply set

contentDisplay = ContentDisplay.GRAPHIC_ONLY

within the fold. It appears to work fine, the buttons are aligned and stick to the right side as intended.

Ah, yeah I was aware that you can't use transitions in JavaFX's css implementation I was just wondering more if TornadoFX had done anything for animating in a stylesheet that I missed somewhere

Shan

Does anyone have any idea how to set the Stage background color of a ModalWindow to semi-transparent? I can set the opacity to .8 or so but that makes everything within the window itself transparent, not just the background. I'm opening a fragment like this:

RenameFragment().openModal(stageStyle = StageStyle.UTILITY, escapeClosesWindow = true)

and setting the stage options from the returned stage to:

newStage.scene.fill = Color.TRANSPARENT

and in my Styles.css I'm setting the vbox root of the

RenameFragment

style to

backgroundColor += Color.TRANSPARENT

and also the

root

class of the Fragment to transparent, but to no effect. 😞

02/02/2019, 12:52 PM

The part with "im a test fragment" should be dark gray but let most of the background come through?

02/04/2019, 8:41 PM

yes, but I also need to find how to make a custom sorter

Shan

02/05/2019, 12:16 PM

says it has a JavaFX implementation

sbyrne

02/05/2019, 4:55 PM

It that how you are trying to launch your TornadoFX component from Swing, or is this after you already have some TornadoFX components visible?

Shan

02/05/2019, 5:12 PM

Not sure I'm understanding exactly what you're trying to achieve, but the issue with the spacing is because the original theme doesn't have a borderColor set I believe. If you set a borderColor on the original theme, the squishing doesn't occur
