B4J Question Do not understand the layout handling

[Midimaster]

I try to learn something from Erels CLVExpandable . But I already have heavy problems in understanding the scope of the variables

code reduced to minimum for poiting to the problem

Sub Process_Globals
...
    Private xui As XUI
    Private lblTitle As B4XView
End Sub

Sub AppStart...
    For i = 1 To 20
        Dim p As B4XView = CreateItem( "Item #" & i)
        clv1.Add(p,...)
    Next
End Sub

Sub CreateItem( Title As String) As B4XView
    Dim p As B4XView = xui.CreatePanel("")
    p.LoadLayout("Item")
    lblTitle.Text = Title
    Return p
End Sub

The Layout "Item" contains a Label named "lblTitle"

How is it possible, that this lblTitle.Text becomes a (different) part of the 20 differend ps? lblTitle is only one global variable. Until now I thought 20 labels also need 20 corresponding variables.

How does p (inside the CreateItem() ) know that the code line with lblTitle.Text is it's lblTitle.Text?

I would have understood something like p.lblTitle.Text. But where is the relation between the loaded Layout and the global variable? And what happens with lblTitle after the 20 asignments?

Would this also work with 20 buttons?

Terms are important. I hope that you are using CLVExpandable. If not then quickly move to the correct one.

The global variable will point to the last loaded view named lblTitle.
