maybe this
https://docs.oracle.com/javase/8/javafx/api/javafx/collections/ModifiableObservableListBase.html
can help you?
you can implement your swap onto a delegate and then just wrap
ModifiableObservableListBase around.

I think the only really effecient way is to have the methods on the interface
of observablelist because the algorithm has to have access to the internal
datastructure.

Hi Peter,
didn't know about that one. It basically does what Tom suggested: makes a copy,
sorts that one, then uses ObservableList.setAll to get one change event. So it
is what I am doing already but still removes/adds children ;-) The remove/add
approach also does work for now, it just could be a little more efficent...

You can also try using FXCollections.sort() directly on the children and
see if that helps since you were wondering about a sort operation. This is
intended specifically for use with ObservableList objects. This has worked
well for me. I don't know how many events this will end up firing, since it
wasn't important to me, but it is worth investigating.
