so .. we want to use tornadofx as a viewer for a non fx based core, what is the best way to make lists observable?
atm i have mostly MutableList and MutableMaps, exposed as List and Maps mostly
is there a way for tornadofx to register a callback that the core can call on change that triggers a update for the observable properties

or would it be a better idea to use coroutines in the core and send updated values via channlels?
can tfx listen to those and convert them into observables ?

Not sure if I'm understanding the issue correctly, but for "what is the best way to make lists observable" can you not just use an ObservableList? https://docs.oracle.com/javase/8/javafx/api/javafx/collections/ObservableList.html

[Shan]

They have an ObservableMap as well

[Shan]

TornadoFX has a wrapper that is obseravbleListOf() that will return a FXCollections ObserableList

[Shan]

then I can call myObservableList.onChange { do stuff }

[Nikky]

yes i can but my core code would be best to not depend on javafx, because its not available on openjdk without openfx

[Nikky]

unless ofc i shadow it in which will break other things..

[Nikky]

so waht i am doing now is making fake observable sollections.. that trigger callbacks, which i can catch on the tfx side and update a actual observablelist

[Shan]

That's the only way I can think to do it, even though it's messy. 😞 I haven't messed around with coroutines within TornadoFX yet so I can't really offer any suggestions. Sorry!

[Nikky]

i could do it another way.. use vars and replace MutableLists with ObservableLists
the core could would nto even notice the swap

[Nikky]

but it would make the code really ugly

[Nikky]

is there any methods on ObservableLists that can replace all contents in one operation? not clear and add all
