    @voddan I think @edvin would be a better resource for that (I don't really understand what you're asking)

    Simply speaking, is there a 
    ObservableList.withIndex()
    so that the result is also observable?

    @voddan can you show a code snippet - it's not clear why you need an index in order for 
    cellFormat
    to work

    how do you show inline snippets in red?

    @gtnarg Just surround it with single backticks

    Copy code
    cellFormat {
    graphic = hbox {
        label(index)  // <--???
        label(it.fmtHex())
    }
}

    @voddan You could try 
    list.indexOf(it)
    , but that looks it would be better suited in a 
    TableView
    or something.

    The items in the list are not unique 😞

    @voddan It looks like you have the item in the it.fmtHex() line...Are you using the index to key into some other data structure?

    11/03/2016, 6:30 PM
    @carlw no, I just display the 
    index
    alongside with the value

    @voddan You were just getting a Kotlin error on the label(String) because of the label(Int) call?

    @voddan - is the index in the 
    ListView
    the same in the 
    ObservableList
    ?

    11/03/2016, 6:37 PM
    @carlw you are right it should be 
    label(index.toString)
    , but that does not change the matter. @gtnarg yes, absolutely

    @carlw You could use 
    "$index "

    @Ruckus I think i would if I keep the extra " "

    @voddan I added a whole program to my example. That numbers the items 0, 1, and 2 along with the values.

    if you can get a reference to the 
    ListCell
    you can call 
    getIndex()

    come from?

    index
    , nether 
    ListCell

    @voddan Press the + button and add in the whole snippet to make sure that cellFormat is in the right place

    I somehow guessed that 
    index
    is available without knowing it

    Just to be clear, the 
    cellFormat
    closure operates on the 
    ListCell
    and since 
    ListCell
    extends 
    IndexedCell
    it has access to 
    IndexedCell.getIndex()
    .
