looks good so far! I want to create a grid to drag-and-drop rectangles in the elements. I thought about using a datagrid, but a gridpane might serve me better to customize how large a cell can be and where it can go

@amanda.hinchman-dominguez uploaded a file:

once such a grid is rendered, I will be trying out how a modelview can be manipulated with a model

I smell a dashboard in the making

that's what it is 😄 currently, dashboards are made manually, and I'm exploring ways to automate the process with a GUI

it's especially fun for me, since tornadofx has a simple boilerplate and is compatible with other languages (convenient for legacy functionality). Saving myself from verbose language on the UI itself will not only make it easy to maintain, but will likely keep the code for others relatively bug-free

A native desktop version of similar tools in web-land. Nice idea.

Can anyone on Linux try to run this app and see if it fails when you bring up the LayoutDebugger? https://github.com/edvin/tornadofx/issues/521#issuecomment-342192471

@amanda.hinchman-dominguez You might want to create your own layout instead. It's not very hard, and it will give you greater insight into the inner workings on the layout engine in JavaFX 🙂

@amanda.hinchman-dominguez I recommend this book: https://www.amazon.com/Mastering-JavaFX-Controls-Oracle-Press/dp/0071833773

@edvin On my Ubuntu 16.04 with Java 1.8.0_155/TornadoFX 1.7.12-SNAPSHOT, I do not get any exception.

@abhinay Thanks for checking :)) I don't even understand how that exception can be thrown, since the scene is always assigned before the debugger is docked. Mystery 🙂

@edvin Could the layout debugger issue be network related? Maybe you can’t get to the JVM and the program never properly initializes the scene?

Hi, I'm still gathering around TornadoFX. I'm currently playing with ViewModels and bindings. One thing I noticed, is that depending on the origin of the object binding doesn't work as I expect. If this is normal, please tell me, I'll be glad to know how it really works. I got a POJO that I try to bind with an ItemViewModel

public class PersonJava {
        private String name;
        private String title;
        // and so on...
    }
    class PersonJavaModel : ItemViewModel<PersonJava>() {
        val name = bind { item?.observable(PersonJava::getName, PersonJava::setName) }
        val title = bind { item?.observable(PersonJava::getTitle, PersonJava::setTitle) }
    }

This works pretty well. Now, I tried to do the same with a data class

data class PersonKotlin(var name: String? = null, var title: String? = null)

    class PersonKotlinModel : ItemViewModel<PersonKotlin>() {
        val name = bind { item?.observable(PersonKotlin::name) }
        val title = bind { item?.observable(PersonKotlin::title) }
    }

Here the bind function doesn't agree because my props are nullable. But why does this work with POJOs ? they nullable too. + I tried to put the annotation @nullable on my POJO's props and this end with a compile exepction like with my data class, because my getters retrieve String? instead of String!, the type inference does its job here. With my POJO I still can manipulate instances with null values in my UI and this works fine. So why I cannot use nullable values with data classes and ItemViewModel ?

I don't understand the problem exactly. But when calling the Java setters the type is inferred to be "String!". Which is a backward compatible way of saying, there might be a null but we don't know for sure. It is a Kotlin thing to avoid too many false positives (which would happen if the inferred type would be String?

@edvin thanks for the book suggestion; sorry, I've been dealing with a particularly difficult client all day today - in any case, I will be using datagrid for the time being (so as not to worry about custom layouts) and will continue on with the general discussion of ViewModels and bindings later today!

Hey guys, I'm still having trouble bundling my TornadoFX app as a dmg on my macbook, anyone have any idea why this command is failing?

I already double checked and there is a jar in the directory listed in the -srcdir argument

by inject will instantiate it

by only classes that inherit from Controller, Model, View, Fragment can be instantiated by inject

there is a way to use DI from for example spring or guice

@edvin could it be that there is a problem when you get a error dialog?

clone my imdbfx thingy, run it and press "search" without filling anything in you will get a error dialog

@ron uploaded a file:

now the program itself will not quit when you press the famous X

if you dont force the error dialog, the program stops without issue when you press X

anyone using coroutines in tornado fx? I want to have an api status to check endpoints, and I reckon coroutines would be the way to go to run multiple at once and update the UI

@pike not yet. edvin's waiting for them to move out of experimental. is it possible to do what you're doing as a straight-up Task with iteration? how will coroutines help this?

Oh, I’m sure I can do a straight up task with iterations, but I was studying & using coroutines for android and was just curious

i think coroutines will help some scenarios a lot
