          javax.swing.JComponent
              javax.swing.JPanel
                  visad.java2d.VisADCanvasJ2D

All Implemented Interfaces:

Accessible, ImageObserver, MenuContainer, Runnable, Serializable

public class VisADCanvasJ2D

extends JPanel

implements Runnable

VisADCanvasJ2D is the VisAD "Canvas" for Java2D. But not really a Canvas, since Canvas is heavyweight.

renderer -

w -

h -

Method Detail

getBackgroundColor

public float[] getBackgroundColor()

Return the background color.

Returns:

A 3 element array of float values in the range [0.0f - 1.0f] in the order (Red, Green, Blue).

setBackgroundColor

public void setBackgroundColor(float r,
                               float g,
                               float b)

Set the background color. All values should be in the range [0.0f - 1.0f].

Parameters:

r - Red value.

g - Green value.

b - Blue value.

setDirect

void setDirect(VisADGroup d,
               VisADGroup nd)

setClip

void setClip(float xlow,
             float xhi,
             float ylow,
             float yhi)

unsetClip

void unsetClip()

addMouseBehavior

public void addMouseBehavior(MouseBehaviorJ2D mouse)

Add a MouseBehavior for mouse control of translation and zoom. This adds MouseListeners to the VisADCanvasJ2D to handle the behaviors for the mouse events. Do not use this in conjunction with other MouseListeners that handle events for the default VisAD mouse controls.

Parameters:

mouse - mouse behavior to add

addKeyboardBehavior

public void addKeyboardBehavior(KeyboardBehaviorJ2D behavior)

Add a KeyboardBehavior for keyboard control of translation and zoom. This adds a KeyListener to the VisADCanvasJ2D to handle the behaviors for the arrow keys. Do not use this in conjunction with other KeyListeners that handle events for the arrow keys.

Parameters:

behavior - keyboard behavior to add

createImages

public void createImages(int len)

scratchImages

public void scratchImages()

renderTrigger

public void renderTrigger()

trigger render to screen

stop

public void stop()

run

public void run()

Specified by:

run in interface Runnable

paintComponent

public void paintComponent(Graphics g)

drawAppearance

public static void drawAppearance(Graphics graphics,
                                  VisADAppearance appearance,
                                  AffineTransform t,
                                  Rectangle2D.Float clip)

This assumes only VisADPointArray or VisADLineArray.

Parameters:

public AffineTransform getTransform()

getPreferredSize

public Dimension getPreferredSize()

setPreferredSize

public void setPreferredSize(Dimension size)

getAutoAspect

public boolean getAutoAspect()

setAutoAspect

public void setAutoAspect(boolean auto)
