Class ViewPlatformAWTBehavior

All Implemented Interfaces:
KeyListener, MouseListener, MouseMotionListener, MouseWheelListener, EventListener
Direct Known Subclasses:
OrbitBehavior

public abstract class ViewPlatformAWTBehavior extends ViewPlatformBehavior implements MouseListener, MouseMotionListener, KeyListener, MouseWheelListener
Abstract class which implements much of the event tracking and state updating in a thread safe manner. AWT Events are captured and placed in a queue. While there are pending events or motion the behavior will wake up every frame, call processAWTEvents and integrateTransforms.

Java 3D 1.2.1

    • ViewPlatformAWTBehavior

      protected ViewPlatformAWTBehavior()
      Parameterless constructor for this behavior, intended for use by subclasses instantiated through ConfiguredUniverse. Such a constructor is required for configurable behaviors.

      Java 3D 1.3
    • ViewPlatformAWTBehavior

      protected ViewPlatformAWTBehavior(int listenerFlags)
      Construct a behavior which listens for events specified by the given flags, intended for use by subclasses instantiated through ConfiguredUniverse.
      Parameters:
      listenerFlags - Indicates which listener should be registered, one or more of MOUSE_LISTENER, MOUSE_MOTION_LISTENER, KEY_LISTENER, MOUSE_WHEEL_LISTENER
      Since:
      Java 3D 1.3
    • ViewPlatformAWTBehavior

      public ViewPlatformAWTBehavior(Canvas3D c, int listenerFlags)
      Constructs a new ViewPlatformAWTBehavior.
      Parameters:
      c - The Canvas3D on which to listen for events. If this is null a NullPointerException will be thrown.
      listenerFlags - Indicates which listener should be registered, one or more of MOUSE_LISTENER, MOUSE_MOTION_LISTENER, KEY_LISTENER, MOUSE_WHEEL_LISTENER

    • setListenerFlags

      protected void setListenerFlags(int listenerFlags)
      Sets listener flags for this behavior.

    • initialize

      public void initialize()
      Initializes the behavior. NOTE: Applications should not call this method. It is called by the Java 3D behavior scheduler.
      Specified by:
      initialize in class Behavior
    • processStimulus

      public void processStimulus(Enumeration behEnum)
      Process a stimulus meant for this behavior. NOTE: Applications should not call this method. It is called by the Java 3D behavior scheduler.
      Specified by:
      processStimulus in class Behavior
      Parameters:
      behEnum - an enumeration of triggered wakeup criteria for this behavior
    • setEnable

      public void setEnable(boolean state)
      Overload setEnable from Behavior. Adds/Removes the AWT listeners depending on the requested state.
      Overrides:
      setEnable in class Behavior
      Parameters:
      state - true or false to enable or disable this Behavior
    • setViewingPlatform

      public void setViewingPlatform(ViewingPlatform vp)
      Sets the ViewingPlatform for this behavior. This method is called by the ViewingPlatform. If a sub-calls overrides this method, it must call super.setViewingPlatform(vp). NOTE: Applications should not call this method.
      Overrides:
      setViewingPlatform in class ViewPlatformBehavior
      Parameters:
      vp - the target ViewingPlatform for this behavior
    • processAWTEvents

      protected abstract void processAWTEvents(AWTEvent[] events)
      This is called once per frame if there are any AWT events to process. The motion variable will be true when the method is called. If it is true when the method returns integrateTransforms will be called immediately. The AWTEvents are presented in the array in the order in which they arrived from AWT.
    • integrateTransforms

      protected abstract void integrateTransforms()
      Called once per frame (if the view is moving) to calculate the new view platform transform
    • queueAWTEvent

      protected void queueAWTEvent(AWTEvent e)
      Queue AWTEvents in a thread safe manner. If subclasses override this method they must call super.queueAWTEvent(e)
