Touch event injection

On BlackBerry® devices with touch screens, you can inject a touch event, such as the slide or tap of a finger on the screen, by

using the EventInjector.TouchEvent class available in the net.rim.device.api.system package. For example,

you can use touch event injection to automate the testing of your application or to allow interaction between a peripheral and

a BlackBerry device.

To download a sample application that demonstrates how to use touch event injection, visit www.blackberry.com/go/

toucheventinjectorsampleapp. For more information about the sample application, visit www.blackberry.com/go/devguides to

read the Touch Event Injector Sample Application Overview. For more information about touch event injection, see the BlackBerry

Java Application UI and Navigation Development Guide and the API reference for the BlackBerry® Java® Development

Environment.
