you don't care about the equals() in a mathematical sense? ex {1,2} = {1,2} if the second list has a listener attached to it and the first doesn't

In this specific case, I do not

ok. you could also override ObservableList if you didn't want to create the extra observable() object

...provide your hashCode-oriented equals()

class CustomListProperty<T> : SimpleListProperty<T>() { override fun equals(other: Any?): Boolean { if( other == null ) return false return super.hashCode().equals(other!!.hashCode()) } }

@aimozg uploaded a file: Propertiy&lt;ObservableList&gt;

I got interesting output

SimpleListProperty not only fires onChange after setValue() of equivalent list, but also fires onChange when the stored list is changed

SimpleListProperty is an ObservableList in addition to being an ObservableValue

Right - as an observable, it's going to register new data any time something changes, including the stored list.

Do you only want it to fire after you setValue() of the equivalent?

No; this behaviour actually saves me from manual rebinding to the stored list

@aimozg have you seen any of @thomasnield’s recent post on tracking the state of the lists?

@carlw no

looking for his project...he had some wrapper classes that might be where you're headed

thanks; I've almost started writing these myself

He's usually on here if you have any questions just loop him in

Does anyone know of an easy way to create a bidirectional binding with conversion? (Specifically between two properties where neither is a

<String>

)

Say I have this:

val picker = ColorPicker()
val property = SimpleObjectProperty<MyColor>()

fun Color.convert(): MyColor { ... }
fun MyColor.convert(): Color { ... }

How do I bind

picker.valueProperty()

to

property

?

Have you looked at Bindings.createObjectBinding()

Bindings.select might be a possibility too

I'm not aware of either of those being bidirectional. Am I missing something?

checking Bindings.bindBidirectional with some object property examples

That one only allows ether two properties of the same type, or two of different types provided one of them is a String.

I don't see anything for two arbitrary types.

Looks like I'll just have to dig into

StringConversionBidirectionalBinding

and see how hard it is to make my own.

use the String conversion as a middle step?

No, just seeing how it works and creating my own class with similar functionality.

It's just 800 lines long, so I was hoping there was an existing solution.
