@carlw I try to avoid singleAssign. In this case I would have used an event, or just used a local val instead, like this:

local var looks nice...you'd only use the event if you were going for a parent and not a distant ancestor right? no event.source.parent.parent.parent

@carlw For events the hierarchy doesn't matter anymore. But I wouldn't use lookup to traverse up and down to find something I think.

yeah stuff like event.source.parent.children[0] looks like a certain other language

Yes, that's no good. This is what I mean by event approach:

We might need better support for scoping events. I will place it on my ever growing list of things to do after Java One 🙂

Should be easy though.

i like the val fp / fp.clear() version the best out of these three. Scratch, that MIT site for kids, is big into message passing so i'll keep an open mind

The EventBus comes into play when sending messages to multiple views?

I was using the Event Bus to support MVVM and an asynchronous design. The ViewModel calls for a Model update or data retrieval. When the Model is finished, it posts an event which is a prompt for everyone to get updated data if they want to.

@zealous Yes, they are global by default.

You can however scope them.

This would fire only in the current scope:

But for this to work, you'd need to use scopes to segregate the different parts of your UI. That's a good idea though.

Hey! New to TornadoFX, and I'm working to create my own GUI for xml creation. I started with a provided open-source sample (thanks edvin), but for some reason, Kotlin is having a hard time importing other Kotlin files in the project. Any suggestions?

Seems like an issue with your project configuration and Kotlin runtime.

@edvin. I'm not by my computer. Do you think Amanda's problem could be with the jvm setting being set to 1.6?

@carlw That usually presents itself as inlining failures, doesn't it?

I think so. Wasn't sure if the type inference error was related.

Could be. @amanda.hinchman-dominguez It doesn't look like you're using a build tool. Are you using the

-jvm-target 1.8

command line option?

@carlw @amanda.hinchman-dominguez Yeah, like @Ruckus mentioned, check the JVM Target, but also make sure that Kotlin API is 1.1 and that you're on Java 8.

@amanda.hinchman-dominguez Maybe you could start with a template project that the IDEA plugin can generate for you? I suggest the Maven based one, it has less quirks in IDEA 🙂

In this example I override default settings with specific configuration for the project. I've set it up without a build tool, just tornadofx.jar on the class path.

While this works, you're much better off with a build tool for several reasons, so you really should check out the project template @amanda.hinchman-dominguez
