Looking at your example, the ABMShared.BuildParagraph call is how the ABMLabel was added to R2C3 on your page.

This could be looking like this.

B4X:

public Sub BuildParagraph(page As ABMPage, id As String, Text As String) As ABMLabel
    Dim lbl As ABMLabel
    lbl.Initialize(page, id, Text , ABM.SIZE_PARAGRAPH, False, "justify")
    Return lbl
End Sub

This method creates an ABMLabel component in memory and then thats gets added to R2C3. In this particular instance you can do two things, 1 declare an ABMLabel in Class_Globals and reference it or simply in btn_clicked add

B4X:

Dim lbl as ABMLabel = page.Components("id2")
lbl.Text = "Gianni Maione"

What the AddComponent did was to call the BuildParagraph method, which created an ABMLabel component and then added it to the page. All components that get added to a page will sit in a "Components" object that you can then get using the ID of the component you created, thus page.Components(xxx) call.

All the best...
