Hello guys, I'm getting an error when I try to execute the app. I have two modules, one for network, and one for views, the behaviour is the follow: 1. If I use `application`plugin, everything works fine 2. If I use

TornadoFX App

run configurations, I get ->

Caused by: java.lang.NoClassDefFoundError: com/sergiocasero/network/ApiService

3. If I use FxLauncer -> Same than 2

@gtnarg I've committed something that might solve the onEdit issue. Let me know 🙂

Is that what you're looking for?

I usually go to get custom fonts from Google https://fonts.google.com/

np!

Hi all, you have not seen me for a while but after a long time I’m back, I’m still in hospital but try to start with tornadofx again

I would like to start with a question, say we have 2 scrollable views side by side and I would like to sync the scrollbar, so when I scroll one view, the other one beside the view shall be scrolled to the same position. How would I realize this?

@carldea Nice! In your stylesheet you have declared pixel values like this:

strokeWidth = Dimension(2.0, Dimension.LinearUnits.px)

. We have extension functions for those, so you should just write

strokeWidth = 2.px

@carldea Also in the CSS, where you use

property = multi(value)

You can just use

property += value

Off topic: Here's one of the new decorations for this year

Just noticed something very problematic. It seems the JavaFX

ComboBox

does not like null values at all. Try selecting

null

in the dropdown and it will throw an error.

But I'll see if this is resolved in the OpenJFX possibly.

@carlw sigh alright, although that can be Kotlin's job with the null-type system.

A funny curiousity - adding

null

as an item is totally valid for

choicebox

🙂

Hello all. Back to working on my project after a break and have been thinking about TornadoFX's type safe css. Coming from a web dev background, I've always done my CSS in this way:

menu, menuButton, otherThing { some styles }

where I would apply a specific set of styles to multiple css classes just by adding them to the list before the style declaration. As far as I can tell, the only way to achieve something like this in Kotlin would be to make a function that would loop through every css element argument and apply the styles to each one. Is there a reason TornadoFX's type safe css doesn't allow this sort of functionality (Kotlin coding conventions I would assume, but maybe there is a different reason? For safety, or something), or are there plans to add something like this in the future? I would be interested in hearing any sort of arguments against this sort of thing, as well! God knows there are thousands of code safety hazards in web development.

i was trying to look that up yesterday after reading the original question. I think select() could use a nice little blurb in the documentation. the shortened s() is used in an example but doesn't have much explaining what it is or how its used.

Hey all! Wondering if there is an easy way to bind something with some kind of offset in place, like binding something to the stage's widthProperty but always subtracting a certain amount? Do I need to bind to a different property I make which is

= widthProperty() - customSubtractValue)

, or is there a way to do this without having to create a custom property (if this is even possible 😬)? This is what I'm trying to do, but obviously it will not work as I cannot subtract a

.px

val from an observable property.

prefWidthProperty().bind(primaryStage.widthProperty() - sideBarWidth)

not always as cleanly and nice as when making things from scratch with tornadofx, but still quite compatible and nice to work with. I'm using JFoenix's Drawer, Hamburger Button, and Switch in my TornadoFX based app.

I am setting the "alignment" to Pos.BASELINE_LEFT for the class "label-container".

Hey there! Maybe someone can help me figure this out:

class MyApp : App(Workspace::class, Styles::class) {
    init {
        with (workspace) {
            // This does NOT remove the forwardButton
            forwardButton.removeFromParent()
            // This does
            header.items.remove(forwardButton)
            // And so does this
            header.getChildList()?.remove(forwardButton)
        }
    }
}

However, the implementation of

removeFromParent()

says

when (this) {
        […]
        is Node -> {
            (parent?.parent as? ToolBar)?.items?.remove(this) ?: parent?.getChildList()?.remove(this)
        }
        […]
    }

The

forwardButton

is a

Node

and is created within a

toolbar

builder, so its parent should be set to that toolbar. Therefore, I’m a bit confused by the

parent?.parent

part on the left of the Elvis operator. I then tried printing the

forwardButton

(which is a

Button

), its parent (which is

null

) and its parent’s parent (which in that case obviously doesn’t exist). So, at which point in the

Workspace

does the

forwardButton

become an orphan?

https://edvin.gitbooks.io/tornadofx-guide/part2/Workspaces.html says you can remove it workspace.backButton.removeFromParent()

@FRQDO try that code in an onBeforeShow() rather than an init block in the App subclass

@ianbrandt you need to specify a finite cyclecount. your loop will never finish (it's indefinite)

Hi all, I am having difficulties in performing validation. I will like the validation error to appear once I click on the submit button.

I'm writing a small .NET/WFP app today and I already miss JavaFX/TornadoFX 🙂 Do those guys still use INotifyPropertyChanged for observable properties? Reminds me of good 'ol PropertyChangeEvent.. but it's 2018, they must have some kind of observable properties you don't have to write manually, right? Confused..

JFXtras has agenda and icalendar modules that might be a fit http://jfxtras.org/
