All Implemented Interfaces:

FocusListener, ImageObserver, MenuContainer, Serializable, EventListener, Accessible

public class Canvas3D
extends Canvas3D
implements FocusListener

A Canvas3D with these special features:

• Does not receive keyboard focus, so that the Return key activates the default button of a keyboard focus chain instead of being consumed by the canvas.

  Caution: Do not use if the canvas is the only component in a focus chain.

• Upon painting the canvas the very first time a listener is notified.

Method Detail

addPaintListener

public void addPaintListener(Canvas3D.IPaintListener listener)

Adds a listener for notification.

This implementation only supports one listener at any one time.

Parameters:

listener - the listener

focusGained

public void focusGained(FocusEvent e)

Invoked when a component gains the keyboard focus. Move focus to the next component that can accept focus. CAUTION: This causes a loop if the canvas is the only component in a focus chain.

Specified by:

focusGained in interface FocusListener

Parameters:

e - a focus event

focusLost

public void focusLost(FocusEvent e)

Invoked when a component loses the keyboard focus. No action needed.

Specified by:

focusLost in interface FocusListener

Parameters:

e - a focus event

isFocusable

public boolean isFocusable()

Overrides:

isFocusable in class Component

See Also:

Component.isFocusable()

paint

public void paint(Graphics g)

After painting the canvas, notifies any registered listener if this is the very first time that this method was invoked.

Overrides:

paint in class Canvas3D

See Also:

Component.paint(java.awt.Graphics)

removePaintListener

public void removePaintListener(Canvas3D.IPaintListener listener)

Removes the listener for notification.

Parameters:

listener - the listener
