Interface SensorStatusListener

All Known Implementing Classes:

CursorManager, OGLBrowserCanvas, VRMLBrowserCanvas

public interface SensorStatusListener

A listener to notify that a sensor's status has changed in relation to an input device. Any VRML/X3D node that interacts with a tracker will issue these events. TODO: This interface does not allow you to seperate events when the user has multiple picking devices like two gloves. In the future we will add parameters to determine which device was used.

Method Detail

deviceOver

public void deviceOver(int type,
                       java.lang.String desc)

Invoked when a sensor/anchor is in contact with a tracker capable of picking.

Parameters:

type - The sensor type

desc - The sensor's description string

deviceNotOver

public void deviceNotOver(int type)

Invoked when a tracker leaves contact with a sensor.

Parameters:

type - The sensor type

deviceActivated

public void deviceActivated(int type)

Invoked when a tracker activates the sensor. Anchors will not receive this event, they get a linkActivated call.

Parameters:

type - The sensor type

linkActivated

public void linkActivated(java.lang.String[] url)

Invoked when a tracker follows a link.

Parameters:

url - The url to load.
