Hai,

How to detect ALT key pressed in Os7...

Can I use the below source for os 7 also? ,

protected boolean keyStatus(final int keycode, final int time) {

if (Keypad.key(keycode) == Keypad.KEY_ALT) {

...

return true;

} else

return super.keyStatus(keycode, time);

}

and also I want to know which is the return of this method? In Detail
How to detect other key press also?
what are the updations or modifications in code, os7 over os6?

the keycode is a bit pattern, if you use '==' to compare it you won't get accurate results, you have to use the '&' operator.

Hai, Which JDE version used for BlackBerry os7 development?
Can I use JDE5 to develop os7 source?

[peter_strange · Accepted solution]

OS development is mostly forward compatible, in that something you develop in OS 5.0 should work in OS 7.0.  However if you are developing only for OS 7.0 and above devices, I would recommend that you establish an OS 7.0 development environment and use that.  This will mean you get full access to the new facilities in OS 7.0, like the new Ui Fields and control mechanism. 

To answer your questions directly:

Q: Which JDE version used for BlackBerry os7 development?

A: Any JDE up to and including JDE 7, but I personally would not recommend anything earlier than 5.0
Q: Can I use JDE5 to develop os7 source?

A: Yes.
