Default Locking the device

Please Login to Remove!

Hi all,

I'm new to the blackberry APIs (done quite a bit of J2ME in the past). I came across an interesting little application - AutoLock (sorry, can't provide a link... forum's rule for newbees), which effectively lock the device until user is unlocking it.

I spent few hours looking for source-code example that will help me understand how to intercept/ignore the app switching (alt-esc) but could not find anything helpful. I dug some more in the APIs documentation and the only theory I came up with is to use a KeyListener, but even then - I'm pretty sure that my application will not be the first app to process the keypress, and therefore will not prevent the alt-esc from switching away from it.

Any idea?
Thanks,
David.

You cannot intercept ALT-ESC.

You *can* override UiApplication.deactivated() to know that you are getting preempted by this key sequence or the "redphone" key.

Ok... however, this will only notify me without letting me do anything about it... right? When the application I mentioned (AutoLock) is foreground, alt-esc does nothing...
Thanks for your help.
