Field Detail

MANUAL_WAKEUP

public static final int MANUAL_WAKEUP

Set this flag if you want to manually wakeup the behavior.

Constant Field Values

INVERT_INPUT

public static final int INVERT_INPUT

Set this flag if you want to invert the inputs. This is useful when the transform for the view platform is being changed instead of the transform for the object.

Constant Field Values

Constructor Detail

MouseBehavior

public MouseBehavior(javax.media.j3d.TransformGroup transformGroup)

Creates a mouse behavior object with a given transform group.

Parameters:

transformGroup - The transform group to be manipulated.

MouseBehavior

public MouseBehavior(int format)

Initializes standard fields. Note that this behavior still needs a transform group to work on (use setTransformGroup(tg)) and the transform group must add this behavior.

Parameters:

format - flags

MouseBehavior

public MouseBehavior(java.awt.Component c,
                     javax.media.j3d.TransformGroup transformGroup)

Creates a mouse behavior that uses AWT listeners and behavior posts rather than WakeupOnAWTEvent. The behaviors is added to the specified Component and works on the given TransformGroup. A null component can be passed to specify the behaviors should use listeners. Components can then be added to the behavior with the addListener(Component c) method.

Parameters:

c - The Component to add the MouseListener and MouseMotionListener to.

transformGroup - The TransformGroup to operate on.

Since:

Java 3D 1.2.1

MouseBehavior

public MouseBehavior(java.awt.Component c,
                     int format)

Creates a mouse behavior that uses AWT listeners and behavior posts rather than WakeupOnAWTEvent. The behavior is added to the specified Component. A null component can be passed to specify the behavior should use listeners. Components can then be added to the behavior with the addListener(Component c) method. Note that this behavior still needs a transform group to work on (use setTransformGroup(tg)) and the transform group must add this behavior.

Parameters:

format - interesting flags (wakeup conditions).

Since:

Java 3D 1.2.1

Method Detail

setTransformGroup

public void setTransformGroup(javax.media.j3d.TransformGroup transformGroup)

Swap a new transformGroup replacing the old one. This allows manipulators to operate on different nodes.

Parameters:

transformGroup - The *new* transform group to be manipulated.

getTransformGroup

public javax.media.j3d.TransformGroup getTransformGroup()

Return the transformGroup on which this node is operating

initialize

public void initialize()

Initializes the behavior.

Specified by:

initialize in class javax.media.j3d.Behavior

wakeup

public void wakeup()

Manually wake up the behavior. If MANUAL_WAKEUP flag was set upon creation, you must wake up this behavior each time it is handled.

processMouseEvent

public void processMouseEvent(java.awt.event.MouseEvent evt)

Handles mouse events

processStimulus

public abstract void processStimulus(java.util.Enumeration criteria)

All mouse manipulators must implement this.

Specified by:

processStimulus in class javax.media.j3d.Behavior

addListener

public void addListener(java.awt.Component c)

Adds this behavior as a MouseListener, mouseWheelListener and MouseMotionListener to the specified component. This method can only be called if the behavior was created with one of the constructors that takes a Component as a parameter.

Parameters:

c - The component to add the MouseListener, MouseWheelListener and MouseMotionListener to.

Throws:

java.lang.IllegalStateException - if the behavior was not created as a listener

Since:

Java 3D 1.2.1
