Class ViewPlatformAWTBehavior

  • All Implemented Interfaces:
    java.awt.event.KeyListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.MouseWheelListener, java.util.EventListener
    Direct Known Subclasses:
    OrbitBehavior
    public abstract class ViewPlatformAWTBehavior
extends ViewPlatformBehavior
implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.KeyListener, java.awt.event.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.
    Since:
    Java 3D 1.2.1

      • 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​(java.util.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
