JavaFX - Multiple selection in a ListView

[Defender14]

Hello,
Is it possible to select multiple items in a ListView JavaFX? I had the idea to insert checkbox in my ListView but it does not work. Could you help me? Thank you in advance. Also, if you have any other alternative for the listview then please let me know. Thank you.

Check out the following code

lstvw = javafx.scene.control.ListView (
            layoutX: 51.0
            layoutY: 85.0
            wd: 380.0
            ht: 151.0
            Vertical:false
            lyinf: javafx.scene.layout.lyinf (
                wd: bind ListView.wd
                ht: bind ListView.ht
            )
            items: [Selection()]
            cellFactory: function() (
              def cell2: lst lst =(
                 nd: CheckBox (
                 visible: bind not cell2.empty
                 selected: false
                 txtalg: txtalg.LEFT
                 allowTriState:false
               )
              )
              def cell: lst lst = (
                 nd : Label (
                 text: bind if(cell.empty) THEN " else "() cell.item"
                 tvfl: bind if(cell.selected) Then clr.WHITE else if (cell.Index mod 2 == 0) Then clr .RED else clr.DarkBlue
                 font: bind if (cell.Index mod 2 == 0) THEN Font.do("Verdana", FontWeight.BOLD, 11.0) else Font.do("Verdana", FontWeight.REGULAR, 11.0)
                 txtalg: txtalg.CENTER
                )
              )  
        )
        );

This is the main method in the above part and I have modified it a little

cellFactory: function() (
                def cl: lst lst =(
                    node: RadioButton (
                        graphicVPos: VPOS.CENTER
                        graphic: Label (
                         text: bind if(cl.empty) THEN " else "() cl.item "
                         textFill: bind if(cl.selected) Then clr.WHITE else if (cl.Index mod 2 == 0) Then clr.RED else clr.DarkBlue
                         font: bind if (cl.Index mod 2 == 0) Then Font .make("Verdana", FontWeight.BOLD, 11.0) else Font.do("Verdana", FontWeight.REGULAR, 11.0)
                         textAlignment: TextAlignment.CENTER
                        )
                        blocksMouse: false

This is what i use for doing the same

Class ListViewItem
(
    var sel: Boolean = false; var value: String; override function toString(): String ( "(if (sel)"#"else"-") (value) )
)
class ListViewCell extends listcell
(
    / / Create the share of the cell
    CheckBox def st = (); Label def text = ();
    / / Create the nd
    init
    (
        nd = HBox
        (
            content: [ st, text ]
        )
    )
    / / Init recycled gold created nodes: the update When controls st of the item is changed
    itemWatcher var = item bd we replace
    (
        if (item! = null) / / Called with null Often, For Some Reason, can Be worth skipping thesis
        (
            st.sel = (item as ListViewItem).sel, text.text = item.toString();
        )
    )
    / / Watch the checkbox st to persist it in the item
    var bd = itemStateWatcher st.sel we replace
    (
        (item as ListViewItem).sel = itemStateWatcher; text.text = item.toString(); onUpdate(); / / Update view (text)
    )
)
function gtcl(): listcell
(
    ListViewCell ()
)
 
var listStuff: ListView listview =
(
    layoutX: 50, layoutY: 50
    layoutInfo: LayoutInfo ( height: 300, width: 200 )
    cellFactory: gtcl items: for (i in [ 1 .. 200 ]) ListViewItem ( value: "Item 03d% (i) )
)
/ * var selectedItemWatcher: Object = (bd listStuff.selectedItem we replace SIW def = selectedItemWatcher have ListViewItem; siw.sel = not siw.sel;) * /
 
var sc: sc; Stage
(
    title: "New Tests ListView"
    sc: sc = sc
    (
        width: 500
        height: 500
        fill: Color.Goldenrod
        content: listStuff
    )
)

It annoys me that this forum should log in again after twenty minutes away. In short, I improved a little script that I made to test the listcell and a primitive form of persistence. Your idea of using the check boxes is excellent. So I injected in my code with the advice I gave above (it's good advice, it is best to check they are good!).

Given that dynamic, larger than the list that displays is smaller than in the underlying list, you must do a bind on the item because there is no immutable link between what is posted purpose of the list. The query API is composed of very practical.
