B4X:
Sub CLV1_VisibleRangeChanged (FirstIndex As Int, LastIndex As Int)
Dim ExtraSize As Int = 20
For i = Max(0, FirstIndex - ExtraSize) To Min(LastIndex + ExtraSize, clv1.Size - 1)
Dim p As B4XView = clv1.GetPanel(i)
If p.NumberOfViews = 0 Then
'**************** this code is similar to the code in CreateItem from the original example
p.LoadLayout("f2")
p.GetView(0).Color = Colors.RGB(Rnd(1,255),Rnd(1,255),255)
p.GetView(1).Tag = i
End If
Next
End SubIn this code,what is ExtraSize? why 20 value for it?
