    Private xui As XUI
    Private BBScrollingLabel1 As BBScrollingLabel
    Private TextEngine As BCTextEngine
End Sub

Public Sub Initialize

End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("1")
    TextEngine.Initialize(Root)
    BBScrollingLabel1.TextEngine = TextEngine
    BBScrollingLabel1.Text = $"[b][u]BBScrollingLabel[/u][/b]: [color=red]Red[/color] [color=0xFF08B31F]Green[/color] [color=blue]Blue[/color]. More information: [url]https://www.b4x.com[/url]..............."$

Private Sub B4XPage_Appear
