i've been putting Kotlin classes into Java in my spare time

Aha 🙂

seeing how feasible this would be to bring into project i work on

Here is a very simplistic implementation of `MyItemFragment`:

@User uploaded a file: Untitled

Not really useful at all here, and it's not easy to support editing inside that fragment, so I don't know if there is any point in this really.

We could ofcourse support a ListCellFragment instead, that has access to the cell also.

speaking in kotlin terms...is there duck typing? could you pass an object with Cell method signatures around that isn't a javafx.scene.control.Cell?

No duck typing, but you can pass functions.

speaking of existing clients...have you worked with the Swing bridging components in TornadoFX?

I have embedded TornadoFX components inside Swing using the JFXPanel if that's what you mean?

yep

SwingNode?

Never had the need to go that way 🙂

Something feels off with my little ListView experiment. Need to think about this a little more

This might give you some inspiration https://developer.gnome.org/gtk3/stable/TreeWidget.html

totally different toolkit, but one of the lestard projects had a Global Actions design that reminded me of GTK

Thanks. I think I know what the problem is, but not if it should be "solved".

This small ItemFragment thing is incredibly handy, but it might come up short for advanced use cases. We might just say that for those you need to subclass

ListCell

or even better

SmartListCell

, and there is no problem though.

For your use case @carlw you could now change the TodoItem to:

@User uploaded a file: Untitled

That might be good if you would add editing support right inside the ListCell. If not, you can just skip the whole TodoItemListCell and do:

@User uploaded a file: Untitled

(ItemFragment should probably be renamed if we keep this ItemFragment in TornadoFX)

maybe you should call it "cellPrototype"? That's the term used in XCode / Interface Builder

ex, listview { cellPrototype(...

Maybe 🙂

fragment seems like something is incomplete

And it is, it is actually abstract 🙂

Hehe, but you meant the name of the function that you call?
