public abstract class PickMouseBehavior

extends Behavior

Base class that allows users to adding picking and mouse manipulation to his scene graph (see PickDragBehavior for an example of how to extend this base class). This class is useful for interactive apps.

Constructor Detail

PickMouseBehavior

public PickMouseBehavior(Canvas3D canvas,
                         BranchGroup root,
                         Bounds bounds)

Creates a PickMouseBehavior given current canvas, root of the tree to operate on, and the bounds.

Method Detail

initialize

public void initialize()

Description copied from class: Behavior

Initialize this behavior. Classes that extend Behavior must provide their own initialize method.
NOTE: Applications should not call this method. It is called by the Java 3D behavior scheduler.

Overrides:

initialize in class Behavior

processStimulus

public void processStimulus(java.util.Enumeration criteria)

Description copied from class: Behavior

Process a stimulus meant for this behavior. This method is invoked if the Behavior's wakeup criteria are satisfied and the ViewPlatform's activation region intersect with the Behavior's scheduling region. Classes that extend Behavior must provide their own processStimulus method.
NOTE: Applications should not call this method. It is called by the Java 3D behavior scheduler.

Overrides:

processStimulus in class Behavior

Tags copied from class: Behavior

Parameters:

criteria - an enumeration of triggered wakeup criteria for this behavior

updateScene

public abstract void updateScene(int xpos,
                                 int ypos)

Subclasses shall implement this update function
