Does anyone know how to get the user-selected values from a GtkMultiSelection in Gtk4.jl? I am trying the example code found [here](https://juliagtk.github.io/Gtk4.jl/dev/manual/listtreeview/) and shown below. I can’t seem to find any documentation on how to do it.

```julia-auto
using Gtk4

model = GtkStringList(string.(names(Gtk4)))
selmodel = GtkSelectionModel(GtkMultiSelection(GListModel(model)))

function setup_cb(f, list_item) # here `f` is the item factory
    set_child(list_item, GtkLabel(""))
end

function bind_cb(f, list_item)
    text = list_item[].string
    label = get_child(list_item)
    label.label = text
end

factory = GtkSignalListItemFactory(setup_cb, bind_cb)
list = GtkListView(selmodel, factory)

win = GtkWindow("Listview demo", 250, 800)
sw = GtkScrolledWindow()
win[] = sw
sw[] = list

```

I was able to figure out that the `GtkSelectionModel` emits a “selection-changed” signal so I can detect when a change is made, but I don’t know how to extract the selected values. I’m trying to do something like this (which is not working):

```julia-auto
function ss(w, x, y)
    for child in selmodel.is_selected
        println("$child")
    end
end
signal_connect(ss, selmodel, "selection-changed")

```

I just registered a new version of Gtk4.jl that supports getting the selection from `GtkMultiSelection`. This relies on `GtkBitset`, which previously wasn’t wrapped. There is a new example “listview\_multi.jl”. Eventually I will try to come up with a unified interface for getting the selection from `GtkSingleSelection` and `GtkMultiSelection`.
