        This attribute specifies whether updates of a widget (for example, a textEdit, slider, progress bar, zoom navigator, LCD number or thumb wheel) have been enabled.
      - "verticalScrollBarPolicy" / "vScrollBarMode"
        The attribute "verticalScrollBarPolicy" sets the vertical scroll bar mode of an object e.g. of a textEdit, a tree widget or a table. (Until Version 3.10 "vScrollBarMode")
