Hi. How do I bind the result of a non-observable function to a property? as I understand it, I'd need a ChangeListener for that?

can give an example of what you want to do. If you want to perform an action when a property changes, then you need

property.onChange { newValue -> } // it
// or
// property.addListener(ChangeListener { ob, old, new -> })

private val isConnectedProperty = SimpleBooleanProperty()
private val isConnectedBinding = booleanBinding(isConnectedProperty) { radioController.isStarted() }

So I need to bind various UI elements to whether radio controller has finished starting up or not

[Bogdan]

the function in isConnectedBinding will not work without changing the isConnectedProperty
