public class MultiScrollBarUI
extends ScrollBarUI

Fields

uis

protected Vector 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.

Constructors

MultiScrollBarUI

public MultiScrollBarUI()

Methods

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.

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

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.

getPreferredSize

public Dimension getPreferredSize(JComponent a)

Invokes the getPreferredSize method on each UI handled by this object.

Overrides:

getPreferredSize in class ComponentUI

Parameters:
