visibility
Defines the visibility of the Component. The value can be Visibility.Visible or Visibility.Invisible; the default is Visibility.Visible.
Visibility.Invisible is the same as View.INVISIBLE: the Component is not drawn, but still occupies space in the layout.
Note: Using this API will not change how Visibility Events are dispatched; onVisible and/or onInvisible will work as if this property was not in use.
