Class MattePainter

java.lang.Object
  org.jdesktop.swingx.JavaBean
      org.jdesktop.swingx.painter.AbstractPainter
          org.jdesktop.swingx.painter.MattePainter

All Implemented Interfaces:

Painter

public class MattePainter
extends AbstractPainter

A Painter implementation that uses a Paint to fill the entire background area using that Paint. For example, if I wanted to paint the entire background in Color.GREEN, I would:

  MattePainter p = new MattePainter(Color.GREEN);
  panel.setBackgroundPainter(p);
 

Since it accepts a Paint, it is also possible to paint a texture or use other more exotic Paint implementations. To paint a BufferedImage texture as the background:

  TexturePaint paint = new TexturePaint(bufferedImage, 
      new Rectangle2D.Double(0, 0, bufferedImage.getWidth(), bufferedImage.getHeight()));
  MattePainter p = new MattePainter(paint);
  panel.setBackgroundPainter(p);
 

If no paint is specified, then nothing is painted

Constructor Summary

MattePainter()
Creates a new MattePainter with "null" as the paint used

MattePainter(Color color)
Create a new MattePainter that uses the given color.

MattePainter(Paint paint)
Create a new MattePainter for the given Paint.

Method Summary

Paint	getPaint()
void	paintBackground(Graphics2D g, JComponent component) Subclasses should implement this method and perform custom painting operations here.
void	setPaint(Paint p) Sets the Paint to use.

Constructor Detail

MattePainter

public MattePainter()

Creates a new MattePainter with "null" as the paint used

MattePainter

public MattePainter(Color color)

Create a new MattePainter that uses the given color. This is only a convenience constructor since Color is a Paint, and thus the other constructor is perfectly suited for specify a color as well

Parameters:

color - Color to fill with

MattePainter

public MattePainter(Paint paint)

Create a new MattePainter for the given Paint. This can be a GradientPaint (though not recommended because the gradient will not grow when the component becomes larger), TexturePaint, Color, or other Paint instance.

Parameters:

paint - Paint to fill with

Method Detail

setPaint

public void setPaint(Paint p)

Sets the Paint to use. If null, nothing is painted

Parameters:

p - the Paint to use

getPaint

public Paint getPaint()

Returns:

Gets the Paint being used. May be null

paintBackground

public void paintBackground(Graphics2D g,
                            JComponent component)

Description copied from class: AbstractPainter

Subclasses should implement this method and perform custom painting operations here. Common behavior, such as setting the clip and composite, saving and restoring state, is performed in the "paint" method automatically, and then delegated here.

Specified by:

paintBackground in class AbstractPainter

Parameters:

g - The Graphics2D object in which to paint

component - The JComponent that the Painter is delegate for.
