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 ^TM has been added to the java.beans package. Please see XMLEncoder .

Field Detail

accessibleContext

 
protected AccessibleContextaccessibleContext 

The currently set AccessibleContext object.

Box.Filler

public Box.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

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 getMinimumSize

protected void 
public DimensionpaintComponent getMinimumSize ( 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. Returns the minimum size of the component.

Overrides:

paintComponent getMinimumSize in class JComponent

Parameters: Returns:

g - the Graphics to paint to the size

Throws:

NullPointerException - if g is null

Since:

1.6

See Also:

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

getPreferredSize

 
public DimensiongetPreferredSize () 

Returns the preferred size of the component.

Overrides:

getPreferredSize in class JComponent

Returns:

the size

See Also:

JComponent.setPreferredSize(java.awt.Dimension) , ComponentUI

getMaximumSize

 
public DimensiongetMaximumSize () 

Returns the maximum size of the component.

Overrides:

getMaximumSize in class JComponent

Returns:

the size

See Also:

JComponent.setMaximumSize(java.awt.Dimension) , 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 JComponent

Returns:

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