Enable swipe gestures that users make on the trackpad
By default, swipe
gestures that
BlackBerry® device users make on the trackpad are not enabled on a screen. You must set a navigation property to
enable the generation of trackpad swipe gestures on a screen.
-
Import the required classes and interfaces.
import net.rim.device.api.ui.*;
import net.rim.device.api.ui.container.*;
import net.rim.device.api.ui.input.*;
-
In your screen object, create an
InputSettings object to populate with navigation
properties.
InputSettings nd = NavigationDeviceSettings.createEmptySet();
-
Set the
NavigationDeviceSettings.DETECT_SWIPE property to
1.
nd.set(NavigationDeviceSettings.DETECT_SWIPE, 1);
-
Invoke Screen.addInputSettings() to add the input settings to the screen.
addInputSettings(nd);
You can change the
value of the
NavigationDeviceSettings.DETECT_SWIPE property at any time, not just
when you create the screen.
Code sample
This sample demonstrates how to enable trackpad swipe gestures in a screen's constructor.
public MyScreen()
{
setTitle("Sample Screen");
InputSettings nd = NavigationDeviceSettings.createEmptySet();
nd.set(NavigationDeviceSettings.DETECT_SWIPE, 1);
addInputSettings(nd);
...
}
