Methods

addGestureListener(listener)

Registers a gesture event listener on this controller. Registering event listeners using this function enables applications to prevent the controller's default behavior. Listeners must implement an onGestureEvent method to receive event notifications. The onGestureEvent method will receive one parameter containing the information about the gesture event. Returning true from onGestureEvent indicates that the event was processed and will prevent any further handling of the event. When an event occurs, application event listeners are called before WorldWindowController event listeners.
Parameters:
Name Type Description
listener The function to call when the event occurs.

Throws:
If any argument is null or undefined.

applyLimits()

Overrides:

removeGestureListener(listener)
