@pike You can do

val listOfStrings = jsonArray.map { it as JsonString }.map { it.string }

@carlw Yeah, I guess it depends on the use case, but it would be nice to be able to detect issues and show them before the UI is shut down. Not quite sure what would be the best way to do that. Would be easier with an actual use case.

@thomasnield for the second time I failed to choose suitable braces ...

selectedProperty().toObservable().subscribe{signalController.filterSwitchSubject}

instead of

selectedProperty().toObservable().subscribe(signalController.filterSwitchSubject)

. Which is syntactically close but crucial with regard to emitting events or not.

@kastork You mean you want to shut down the JVM and immediately start a new with the same parameters? I think you'd need to inspect the environment to figure out what parameters was passed, where the java binary is located etc and start a new process before you do System.exit. Maybe there is a library out there for that?

wow. quick hour…install time just went to 1 minute

file:/img/MetroTileHomepage.png doesn't freak out but does not return an image, I guess I'll have to keep playing around with it. I'll let you know what the solution was!

great....the code that reads in the byte[] should be in a Task too with a progress bar (when you get around to it)

@amanda.hinchman-dominguez Do you mean "convert" a TornadoFX Type Safe stylesheet to a text based css file or the other way around? You can get the resulting css text from a type safe stylesheet by calling

render()

on the stylesheet.

Hey guys, I'm having a lot of trouble trying to generate a DMG from a TornadoFX project on OS X. Does anyone know what arguments to supply to javapackager to get it to work properly? (I don't know what the put for all the "-outdir/-outfile" arguments and the documentation I've found on Oracle's website hasn't been so great)

@edvin @amanda.hinchman-dominguez If you want to handle the pagination outside of the datagrid, you can do something simple like this. WARNING: Oscilloscope Content https://courses.bekwam.net/public_tutorials/bkcourse_tornadofx_slideshow.html

@amanda.hinchman-dominguez Will this be OK for your use case? I've committed it now. It still needs some more features to work in every situation but I think it's a good start.

Anyone have recommendations on managing lifecycle of background services inside a JavaFX/tornadofx app? I see that I can override

start

and

stop

methods of

App

to potentially run initialization code there Looking for a clean way to hook into application start/stop for stateful services like database connections without causing any issues for JavaFX

Worked right away, the problem is that the context menu won't show up and click events don't work ;/

@Greg Stepniewski when you tried my example w. anchorpane, did you have anything set on imageview like fitHeight/width?

I just released the new version of the IDEA plugin. It should be available within the hour 🙂

@Marcin Wisniowski Are you not using Maven or Gradle to build your app?

I want to style my entire app, but not a website I'm loading inside a WebView.

And we would have an awesome opportunity to end this Electron nonsense.

@wakingrufus The framework tests contains a few, but no established patterns or best practices I'm afraid. We do need them though!

Which way is preferred to use custom component in DSL? Operator

+=

or create custom builder function?

@snrostov I tend to favor

add

, but if you add the same type of component often, creating a small builder is even better. It takes no time at all 🙂

guys, does anybody know what happened with jpro.io? the site is down last 2 days

What do you mean by "Why can I not reference a mutable variable in type-safe language, but I can change the value of it?"? You can indeed reference a mutable variable and even assign a new value to it.

I think

item?.observable(PersonKotlin::name)

returns

Property<String?>?

for your Kotlin sample. I think the type should be

Property<String?>

instead?

Naive question: what is the value of adding views/fragments to a view using find() dependency injection and params VS calling a constructor and passing args into it? I can see that allowed views to be reused, but if the views are cheap to create, are there any other benefits?

Anyone know how to make a Spinner with the editable property set commit for reasons other than hitting "Enter"? Like if the user tabs out of the control

BTW, I'm working on crossplatform UI framework. Native rendering pipeline is quite different from javaFX. Main rendering/painting/composite concepts: - corutine based parallel rendering pipeline (like https://servo.org/) with ability to postpone rendering of slow components to next frame (like in react fiber) - layouting algorithm works only in simple one pass. Based on simple min/max box constraints (NOT like complex constraints solver in MacOS/iOS and web/css). Size constraints passed down to the tree, layout passed back to up. - benefit from ability of fast performance of compositor (modern hardware very fast on it) - vulkan for windows/linux/android, metal for osx/ios Widgets framework: - react/flutter-like widgets framework: Widget acts as react props and is immutable. State stored in Widget Holder which is hidden for user code. - Mutable listenable editor model used only for editing objects, not widgets (like in javafx) - Code based on common widgets works on web
