Backlight and key listener
 

Hi,

in my application i need to control every key pressed.

Everything is ok until the blackberry change the backlight state.
If the backlight is off and i press a key, my application can't intercept it (is the end key)

Any suggestion?

Thank

Your application will only be able to get key strokes when in the foreground. When the backlight is turned off the OS takes the foreground so the first keystroke can turn the light back on.

thanks for answer!

yes, is it. But the problem is that the first key that i press when the bb is "obscured" is not consumed and bb use it.

I have my application in the top of stack when the "light turn off" and if i press the END char to "turn on the light", the system close the screen (as it must do if i don't intercept the event).
Is the only key that do it, the others doesn't do nothing (i think becouse i can intercept them)...

p.d. sorry for spanglish

You may find under certain circumstances that other keys do not get intercepted. The Start key for example when the phone is ringing.

:?

this means that there aren't any solution?

The event must be generate and a listener must be listen for it...

Any idea?

Thank!!!

Re-examine the use you want to make of the buttons. Why do you want to remap the End Key function?

In the application i have different user level.
One of them is a low privilege user, that can only use this.

To do this, i need that the application stay foreground ever (i know that is a little bit forced, but is the requirement :oops:).

So, I need to control every key, and this is the only moment that i lost it.

And i think that is not so good that if I have an open application, when i can't see the content of display and I press a key, it disappear...

p.d. thank for help

Blackberry OS does not have support for multiple users. Even if you could solve this problem (which I doubt), the security would be dubious at best.

However if you are required to go down this road, you could keep the device on, at the expense of increase battery usage. Read this article.

is different thing, the multiple user is for application.
The bb is a work device and there are many people that use the same.
One is administrator of application, others are simple users.
When the application start ask for user and psw (of itself) and only if is an administrator, he can esc.

The problem of battery is a big problem, so i think that i need another solution.

Thank for help hrbuckley!
