How do I prevent the screen backlight to be switched off? I'm working on a video player and want the backlight kept on during playback.

Thanks,

infidel

This might be impossible
I think there's a function in the HAL (hardware abstraction layer) which allows you to turn the backlight on or off.

However, I'm not sure if the HAL is a public API (probably) and I'm not sure how you would go about disabling the automatic timer switch off. But you may be able to get somewhere by tinkering with the HAL.

Also, of course, this particular HAL function may not be wired up for a given phone. But I think it normally is.

Screen backlight
Hi,

one way to prevent back light from switching off is to call User::ResetInactivityTime() periodically. I don't think there is a public API to do this any other way.

User::ResetInactivityTime only works on Series60 phones.

On P800/P900, use this instead:

Code:
TRawEvent event;
event.Set(TRawEvent::EActive);
UserSvr::AddEvent(event);

Re: Screen backlight
Hi,

is there a possibility to turn on the backlight on a Motorola A925/A1000?

Unfortunately neither User::ResetInactivityTime nor event.Set(TRawEvent::EActive); work Sad

Thank You for Your help
and kind regards

Hi sDegen,

Have you got the SDK manual? Which Symbian 0S is in Motorola A925?

Hi Shagor,

it's Symbian 7.0 SDK for UIQ like in the P900.
The functions work fine in the P900, but not in the A925?!?

Thanks
Steve

Re: Screen backlight
There seems to be a entry in hal_data.h called EBacklightState
