some part of it is also real javascript, but that shouldn't concern so much, I build a ANTLR grammer to recognize the js subset I need

the focus is on that tree structure defined inthe js file by a literal object

i has arrays and objects, im for the most part also not concerned with that difference though - to me its just nodes in a tree and the keys are labeled with the corresponding js-strings

the leaves are values which correspond to text references that are stored in an i18n file (texts taht need to belocalized)

The structure of that i18n file should retain some of the the structure of the javascript configuration file - but be simpler

so what I have decided to do, is just kick out the tree-nodes from the original that have no siblings

You're modeling a JSON object in a TreeView?

well - im not even displaying that tree

just transforming the data

in the end, all im displaying to the user is a joined string of the paths

too bad it's not XML, you could use XSL for that

well, I'm not really deciding on the input xD

just trying to automize its freation

its not even JSON

its an ugly javascript based config file

Right now everyone is writing these js based config files by hand (i.e. copy paste) in this company

Then you have to kind of repeat that process for the i18n files that contain the localizable texts

Its so much work - hence I am writing a production app in TornadoFX that is supposed to automize this stuff.

Afternoon. Can anyone tell me how to attach an expandProperty() to a TreeItem class?

item.expandedProperty().addListener((observable, wasExpanded, isExpanded) -> // do something based upon the expansion property change );

is the suggestion in JavaFX, but can't figure out how to do this in the Kotlin/Tornadofx way

I simply want to intercept the user clicking expand icon in the TreeView. The tree is built dynamically. Which works when node is selected, However, clicking the expand doesn't select the node. So I simply need to put this hook in

@sp33dy are you using the .populate extension function of TreeView<T> ?

Untitled.js

how about this?

No, I couldn't get it to trigger the next child search

thanks, let me go back and try that

lol @ "make babies here"

I've created my on TreeItem and then do an expand when node is onselected

the populare takes two args - the first is the item factory - its default implementation just creates a TreeItem
