B4J Question How to get some information from multiple selected object in tableview?

[prhymery]

I made a tableview and I stored numbers in each cells as object

when I clicked some cell, I got number(object info) of each cells by using below method

Sub TableView1_SelectedCellChanged (RowIndex As Int, ColIndex As Int, Cell As Object)
    Log(Cell)
End Sub

Then, I am trying to get numbers (objects info) during the multiple selection

is there any way to get information from multiple selected cells?

I used below code from table example

Dim jotable As JavaObject=TableView1
   
    Dim joSelMode As JavaObject
    joSelMode.InitializeStatic("javafx.scene.control.SelectionMode")
   
    Dim tvSelModel As JavaObject = jotable.RunMethodJO("getSelectionModel", Null)
   
    tvSelModel.RunMethod("setSelectionMode",Array(joSelMode.GetField("MULTIPLE")))

Maybe can be useful

Another option is to add nodes to the table cells and then you can do more sophisticated things. You can for example add a CheckBox near each item.

Thank you for your quick response
Actually, I already made a node like below code

    For rowIndex = 1 To 16
        Dim row(TableView1.ColumnsCount) As Object
        Dim num As Int
        If rowIndex = 1 Then
        num=rowIndex
        Else If rowIndex <> 1 Then
            num = (32*(rowIndex-1))+1
        End If
            For c = 0 To TableView1.ColumnsCount - 1
                row(c) = num + c
            Next
        TableView1.Items.Add(row)
    Next

you mean, should I add labels?

You are not creating nodes / controls / views. See the tutorial. Instead of creating labels you can create panes with many other views.

Attached the example of you need.

Sorry Erel, I'll watch the tutorial and try this again.
I appreciate your help, Thanks.
