The panel contains several elements.
To change their properties I do:
B4X:
For i = 0 To pn.NumberOfViews - 1
    Dim v As View=pn.GetView(i)
    If pn.GetView(i) Is EditText Then
        Dim et As EditText=v
        et.TextSize=Starter.TextSize
    Else If pn.GetView(i) Is Spinner Then
        Dim sp As Spinner=v
        sp.TextSize=Starter.TextSize
    End
Next
I decided to replace Spinner with B4XComboBox
How can I add B4XComboBox to this function?

For B4x customviews, the actual object is stored in the base panel's Tag property. So you can test for it in the views Tag.

Edit: See Erel's link

The B4xCombobox also exposes the underlying combobox as cmbBox, so you can directly change it's properties.

B4X:
    For i = 0 To Pn.NumberOfViews - 1
        Dim v As B4XView = Pn.GetView(i)
        If V Is EditText Then
            V.TextSize=TextSize
        Else If V Is Spinner Then
            Dim Sp As Spinner = V
            Sp.TextSize = TextSize
        Else If v.Tag Is B4XComboBox Then
            Dim cb As B4XComboBox = v.Tag
            cb.cmbBox.TextSize = TextSize
        End If
    Next

stevel05, this code was what I needed:
B4X:
Dim v As B4XView = Pn.GetView(i)
It was not clear how to define B4XView and View elements in the panel.
Thanks!
