Using gestures

The Gesture API allows a MIDlet to receive notifications when the user interacts with Canvas or CustomItem components. The API registers touch interaction as a series of gesture events.

The Gesture API is supported since Series 40 6th Edition, Feature Pack 1. The Gesture API is packaged as part of the Nokia UI API and consists of the following classes:

  • GestureEvent

  • GestureListener

  • GestureInteractiveZone

  • GestureRegistrationManager

You can combine the Gesture API with the Frame Animator API to create linear drag and kinetic scroll animations. You can also use gesture events together with pointer events to implement touch functionality.

Implementing touch functionality

To implement touch functionality in your MIDlet:

  1. Set the MIDlet to receive gesture events

  2. Define the handling of gesture events in the MIDlet

For more information about the Gesture API classes and methods, see the Gesture API reference.
