All Implemented Interfaces:

MouseBehaviorCallback

public class PickTranslateBehavior
extends PickMouseBehavior
implements MouseBehaviorCallback

A mouse behavior that allows user to pick and translate scene graph objects. Common usage: 1. Create your scene graph. 2. Create this behavior with the root and canvas. See PickRotateBehavior for more details.

Constructor Detail

PickTranslateBehavior

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

Creates a pick/translate behavior that waits for user mouse events for the scene graph.

Parameters:

root - Root of your scene graph.

canvas - Java 3D drawing canvas.

bounds - Bounds of your scene.

PickTranslateBehavior

public PickTranslateBehavior(BranchGroup root,
                             Canvas3D canvas,
                             Bounds bounds,
                             int pickMode)

Creates a pick/translate behavior that waits for user mouse events for the scene graph.

Parameters:

root - Root of your scene graph.

canvas - Java 3D drawing canvas.

bounds - Bounds of your scene.

pickMode - specifys PickTool.PICK_BOUNDS or PickTool.PICK_GEOMETRY.

PickTool.setMode(int)

Method Detail

updateScene

public void updateScene(int xpos,
                        int ypos)

Update the scene to manipulate any nodes. This is not meant to be called by users. Behavior automatically calls this. You can call this only if you know what you are doing.

Specified by:

updateScene in class PickMouseBehavior

Parameters:

xpos - Current mouse X pos.

ypos - Current mouse Y pos.

transformChanged

public void transformChanged(int type,
                             Transform3D transform)

Callback method from MouseTranslate This is used when the Picking callback is enabled

Specified by:

transformChanged in interface MouseBehaviorCallback

Parameters:

type - will be one of ROTATE, TRANSLATE or ZOOM

setupCallback

public void setupCallback(PickingCallback callback)

Register the class @param callback to be called each time the picked object moves
