Swipe gestures with trackpads
Similar to BlackBerry® devices with a touch screen, devices with a trackpad support swipe gestures that BlackBerry device users make on the trackpad.
A TouchEvent object with the event type TouchGesture.NAVIGATION_SWIPE is generated when the user swipes across the trackpad. You can retrieve information about the trackpad swipe by using the following methods:
Code sample: Retrieving information about a trackpad swipe
This sample demonstrates how to handle a trackpad swipe in a screen's touchEvent() method.
protected boolean touchEvent(TouchEvent message)
{
switch(message.getEvent())
{
case TouchEvent.GESTURE:
TouchGesture gesture = message.getGesture();
switch(gesture.getEvent())
{
case TouchGesture.NAVIGATION_SWIPE:
Dialog.alert("Swipe direction: " + gesture.getSwipeDirection()
+ ", "
+ "\nMagnitude: " + gesture.getSwipeMagnitude());
return true;
}
}
return false;
}
