Methods
addListener()
When called, the accelerometer support implementation must begin to notify the specified nsIDeviceMotionListener by calling its nsIDeviceMotionListener.onAccelerationChange() method as appropriate to share updated acceleration data.
void addListener( in nsIDeviceMotionListener aListener );
Parameters
- aListener
- The nsIDeviceMotionListenerobject whosensIDeviceMotionListener.onAccelerationChange()method should be called with updated acceleration data.
Native code only!
addWindowListener
Sets the nsIAccelerometer as the source for MozOrientation events on the specified DOM window.
void addWindowListener( in nsIDOMWindow aWindow );
Parameters
- aWindow
- The DOM window that the accelerometer should begin sending MozOrientationevents to.
removeListener()
Tells the accelerometer to stop sending updates to the specified nsIDeviceMotionListener.
void removeListener( in nsIDeviceMotionListener aListener );
Parameters
- aListener
- The nsIDeviceMotionListenerobject to which no further updates should be sent.
Native code only!
removeWindowListener
Removes the nsIAccelerometer as the source for MozOrientation events on the specified DOM window.
void removeWindowListener( in nsIDOMWindow aWindow );
Parameters
- aWindow
- The DOM window that the accelerometer should stop sending MozOrientationevents to.
