public class MouseZoom

extends MouseBehavior

MouseZoom is a Java3D behavior object that lets users control the Z axis translation of an object via a mouse drag motion with the second mouse button. See MouseRotate for similar usage info.

Constructor Summary

MouseZoom()
Creates a default mouse zoom behavior.

MouseZoom(int flags)
Creates a zoom behavior.

MouseZoom(TransformGroup transformGroup)
Creates a zoom behavior given the transform group.

Method Summary

double	getFactor() Return the y-axis movement multipler.
void	initialize() Initializes the behavior.
void	processStimulus(java.util.Enumeration criteria) All mouse manipulators must implement this.
void	setFactor(double factor) Set the y-axis movement multipler with factor.
void	setupCallback(MouseBehaviorCallback callback) The transformChanged method in the callback class will be called every time the transform is updated
void	transformChanged(Transform3D transform) Users can overload this method which is called every time the Behavior updates the transform Default implementation does nothing

Constructor Detail

MouseZoom

public MouseZoom(TransformGroup transformGroup)

Creates a zoom behavior given the transform group.

Parameters:

transformGroup - The transformGroup to operate on.

MouseZoom

public MouseZoom()

Creates a default mouse zoom behavior.

MouseZoom

public MouseZoom(int flags)

Creates a zoom 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 -

Method Detail

initialize

public void initialize()

Description copied from class: MouseBehavior

Initializes the behavior.

Overrides:

initialize in class MouseBehavior

getFactor

public double getFactor()

Return the y-axis movement multipler.

setFactor

public void setFactor(double factor)

Set the y-axis movement multipler with factor.

processStimulus

public void processStimulus(java.util.Enumeration criteria)

Description copied from class: MouseBehavior

All mouse manipulators must implement this.

Overrides:

processStimulus in class MouseBehavior

Tags copied from class: Behavior

Parameters:

criteria - an enumeration of triggered wakeup criteria for this behavior

transformChanged

public void transformChanged(Transform3D transform)

Users can overload this method which is called every time the Behavior updates the transform Default implementation does nothing

setupCallback

public void setupCallback(MouseBehaviorCallback callback)

The transformChanged method in the callback class will be called every time the transform is updated
