Title: how to lock/unlock the device from Qt/QtQuick via native C++
Post by: huellif on August 21, 2013, 12:52:34 am

1. add

Code: [Select]

LIBS += -lavkon
to your .pro file in Symbian {}

2. include

Code: [Select]

#include "aknkeylock.h"
to your class/header/main.cpp

3. Now put this code into your function:

Code: [Select]

RAknKeyLock aKeyLock;   
CleanupClosePushL(aKeyLock);
User::LeaveIfError(aKeyLock.Connect());
aKeyLock.EnableWithoutNote();
//aKeyLock.DisableWithoutNote();
CleanupStack::PopAndDestroy(&aKeyLock);

really easy ;)

Can I lock the screen but leave it on just like SMS message does?

Ok. When you get a SMS message with phone locked, screen is turned on for a while and showing lockscreen with notification (at least on Belle Refresh). I'd like to replicate such behavior.

first of all it's not possible to add a notification to lockscreen :(
and I don't know how to stop screensaver and show lockscreen
