Import net.rim.device.api.ui.container.*; public class Browserfielddemo extends UIApplication {public static void main (string[] args) {Browserfiel
        Ddemo app = new Browserfielddemo ();
    App.entereventdispatcher ();
    Public Browserfielddemo () {Pushscreen (New Browserfielddemoscreen ()); } class Browserfielddemoscreen extends Mainscreen {public browserfielddemoscreen () {BROWSERFIELDCONFI
        G Mybrowserfieldconfig = new Browserfieldconfig (); Mybrowserfieldconfig.setproperty (Browserfieldconfig.navigation_mode,browserfieldconfig.navigation_mode_pointer
