All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible

Enclosing class:

Box

public static class Box.Filler
extends JComponent
implements Accessible

An implementation of a lightweight component that participates in layout but has no view.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

Constructor Detail

Filler

@ConstructorProperties({"minimumSize","preferredSize","maximumSize"})
public Filler(Dimension min,
              Dimension pref,
              Dimension max)

Constructor to create shape with the given size ranges.

Parameters:

min - Minimum size

pref - Preferred size

max - Maximum size

Method Detail

changeShape

public void changeShape(Dimension min,
                        Dimension pref,
                        Dimension max)

Change the size requests for this shape. An invalidate() is propagated upward as a result so that layout will eventually happen with using the new sizes.

Parameters:

min - Value to return for getMinimumSize

pref - Value to return for getPreferredSize

max - Value to return for getMaximumSize

paintComponent

protected void paintComponent(Graphics g)

Paints this Filler. If this Filler has a UI this method invokes super's implementation, otherwise if this Filler is opaque the Graphics is filled using the background.

Overrides:

paintComponent in class JComponent

Parameters:

g - the Graphics to paint to

Throws:

NullPointerException - if g is null

Since:

1.6

JComponent.paint(java.awt.Graphics), ComponentUI

getAccessibleContext

public AccessibleContext getAccessibleContext()

Gets the AccessibleContext associated with this Box.Filler. For box fillers, the AccessibleContext takes the form of an AccessibleBoxFiller. A new AccessibleAWTBoxFiller instance is created if necessary.

Specified by:

getAccessibleContext in interface Accessible

Overrides:

getAccessibleContext in class Component

Returns:

an AccessibleBoxFiller that serves as the AccessibleContext of this Box.Filler.
