```
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.

```
public MultiViewportUI()
```
- Method Detail
  - getUIs
```
public ComponentUI[] getUIs()
```
    Returns the list of UIs associated with this multiplexing UI. This allows processing of the UIs by an application aware of multiplexing UIs on components.
    Returns:
    an array of the UI delegates
  - contains
```
public boolean contains(JComponent a,
                        int b,
                        int c)
```
    Invokes the contains method on each UI handled by this object.
    Overrides:
    contains in class ComponentUI
    Parameters:
    a - the component where the x,y location is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
    b - the x coordinate of the point
    c - the y coordinate of the point
    Returns:
    the value obtained from the first UI, which is the UI obtained from the default LookAndFeel
    See Also:
    JComponent.contains(int, int), Component.contains(int, int)
  - update
```
public void update(Graphics a,
                   JComponent b)
```
    Invokes the update method on each UI handled by this object.
    Overrides:
    update in class ComponentUI
    Parameters:
    a - the Graphics context in which to paint
    b - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
    See Also:
    ComponentUI.paint(java.awt.Graphics, javax.swing.JComponent), JComponent.paintComponent(java.awt.Graphics)
  - createUI
```
public static ComponentUI createUI(JComponent a)
```
    Returns a multiplexing UI instance if any of the auxiliary LookAndFeels supports this UI. Otherwise, just returns the UI object obtained from the default LookAndFeel.
    Parameters:
    a - the component to create the UI for
    Returns:
    the UI delegate created
  - installUI
```
public void installUI(JComponent a)
```
    Invokes the installUI method on each UI handled by this object.
    Overrides:
    installUI in class ComponentUI
    Parameters:
    a - the component where this UI delegate is being installed
    See Also:
    ComponentUI.uninstallUI(javax.swing.JComponent), JComponent.setUI(javax.swing.plaf.ComponentUI), JComponent.updateUI()

```
public void uninstallUI(JComponent a)
```
    Invokes the uninstallUI method on each UI handled by this object.
    Overrides:
    uninstallUI in class ComponentUI
    Parameters:
    a - the component from which this UI delegate is being removed; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
