Join a client-defined menu item into an existing application (blackberry,model:7520)

model| Menu | program
A few days ago, I was thinking about a problem that extends the BlackBerry System application's menu,

I intend to divide it into several steps:

1 Whether it is really possible to do so, after all, the BlackBerry is another operating system

2 then you can join and how to join

3 after joining, how to achieve their own functions

This problem has been bothering me for a long time, today I looked at the BlackBerry SDK, I found a few classes about menu, and I was thinking that we should be able to start with these. A few days ago, I looked for several open source tools, and unfortunately did not provide the source code, but this shows that the first step is feasible, The next class study is how to implement step 2nd, looking at these classes and their documentation:

The following code was obtained:

Import Net.rim.device.api.ui.*;import Net.rim.device.api.system.*;import Net.rim.device.api.ui.component.Dialog; Import Net.rim.blackberry.api.menuitem.*;import Net.rim.device.api.ui.component.*;import net.rim.device.api.ui.container.*;

public class Bbinit extends application{private static long ID = 0xe1e5ac072dc45f40l;

public static void Main (string[] args) {bbinit Theapp = new Bbinit (); Theapp.entereventdispatcher ();}

Public Bbinit () {applicationmenuitemrepository.getinstance (). AddMenuItem (applicationmenuitemrepository.menuitem_ BROWSER, New Bbmenuitem ()); }

}

Class Bbmenuitem extends Applicationmenuitem {Bbmenuitem () {super ("Print ...", 10);}    Bbmenuitem (int order) {super (order); }

Public String toString () {return "Print ...";}

The public object is run (object context) {System.out.println,//do WHAT you WANT to Doreturn context;}}

This 2nd step has been achieved

The next 3rd step, I believe it is not difficult.
