public class MouseRotate

extends MouseBehavior

MouseRotate is a Java3D behavior object that lets users control the rotation of an object via a mouse.

To use this utility, first create a transform group that this rotate behavior will operate on. Then,

 
   MouseRotate behavior = new MouseRotate();
   behavior.setTransformGroup(objTrans);
   objTrans.addChild(behavior);
   behavior.setSchedulingBounds(bounds);

The above code will add the rotate behavior to the transform group. The user can rotate any object attached to the objTrans.

Constructor Detail

MouseRotate

public MouseRotate(TransformGroup transformGroup)

Creates a rotate behavior given the transform group.

Parameters:

transformGroup - The transformGroup to operate on.

MouseRotate

public MouseRotate()

Creates a default mouse rotate behavior.

MouseRotate

public MouseRotate(int flags)

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

Parameters:

flags - interesting flags (wakeup conditions).

MouseRotate

public MouseRotate(java.awt.Component c)

Creates a rotate 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.

Parameters:

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

Since:

Java 3D 1.2.1

MouseRotate

public MouseRotate(java.awt.Component c,
                   TransformGroup transformGroup)

Creates a rotate 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 behavior 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

MouseRotate

public MouseRotate(java.awt.Component c,
                   int flags)

Creates a rotate 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:

flags - interesting flags (wakeup conditions).

Since:

Java 3D 1.2.1

Method Detail

processStimulus

public void processStimulus(java.util.Enumeration criteria)
