B4J Question Find Form that contain a Node

[Teech]

I have a Layout used in lots of forms and pane, loaded with [container].LoadLayout. In my class i have a Sub like this:

Public Sub LoadLayout(parent As Object,caller As Object)
    mCaller=caller
    If parent Is TabPane Then
        Dim t As TabPane=parent
        t.LoadLayout("EmployeesList","Employees")
    End If
    If parent Is Form Then
        Dim f As Form= parent
        f.RootPane.LoadLayout("EmployeesList")
    End If
    FillEmployeesView
End Sub

This Layout (EmployeesList) has a button that show a DirectoryChooser.
Unfotunatelly i can't find which form is in use to pass as argument in DirectoryChooser.Show.

Sub btCSV_Click
    Dim d As DirectoryChooser
    d.Initialize
    d.InitialDirectory=File.DirTemp
    Dim dir As String   
    dir=d.Show(???) '<--- PROBLEM
   
    If dir<>"" Then
      'Do Something
    End If
End Sub

Could someone help me?
Many thanks

does it work with?

d.Show(MainForm)
d.Show(Main.MainForm)

Sub Process_Globals

    Public MainForm As Form

End Sub

You could just create a form to use

Sub btCSV_Click
    Dim d As DirectoryChooser
    d.Initialize
    d.InitialDirectory=File.DirTemp
    Dim dir As String
    Dim f As Form   ' doesn't even need to be initialized <--- Solution
    dir=d.Show(f) '<--- PROBLEM
   
    If dir<>"" Then
      'Do Something
    End If
End Sub
