in particular, none of this is a javafx aware model. I assume i'll want to sort of make similar replica using javafx properties to use as the view model and have that all hook up? I think probably know where to go with it, I was just wondering if anyone had any good examples where the structure and data changed somewhat often

I've tried to to something like that, I used MutableMap<String, ObservableList<String>> as a structure for TreeView nodes, but it was 2-level hierarchy (category/section)

When populate function returns ObservableList, nodes, such as sections are added automatically

thanks, i'll take a look. I'm still new to all of kotlin, javafx and tornadofx. I'm a long time Java/Swing developer. I'm loving tornadofx just still wrapping my head around some of it.

There mutableMap.keys returns set of strings, thus it does not update category nodes. I think that problem is solvable, but I had not much time to solve it in a better way. Perhaps, if have well-known model like company -> department -> person, you can make your own classes like data class Department(val persons: ObservableList<Person>) and Company(val departments: ObservableList<Department>, val persons: ObservableList<Person>), then feed listOf(company1, company2).observable() to populate function

[ValV]

And cellFormat function will extract node names from those Company, Department, and Person classes (when they are passed as nodes)

yeah i think that is what I'm envisioning. Think I'm going to take a break for a bit and come back to it. Thanks a lot!

It seems that reactive elements (observable properties) of JavaFX -- are the huge improvement over Swing

I have some cleaning up to do, and expanding of my model, but I think i have the general concept working. Thanks a lot for your help!
