  - ### uis

    protected Vector<ComponentUI> uis
    The vector containing the real UIs. This is populated in the call to `createUI`, and can be obtained by calling the `getUIs` method. The first element is guaranteed to be the real UI obtained from the default look and feel.

- ## Constructor Details

  - ### MultiViewportUI

    public MultiViewportUI()
    Constructs a `MultiViewportUI`.

- ## Method Details
