Overview

MScreensaverPluginHost::GetIndicatorPayload(TScreensaverIndicatorIndex aIndex, TIndicatorPayload & aResult); with EScreensaverIndicatorIndexKeyGuardState as the first parameter always returns a non-zero value irrespective of the keypad status.

Detailed description

To create a customized screensaver, MScreensaverPluginHost::GetIndicatorPayload() needs to be used to query the status of Keypad, missed calls, new messages, active profile, etc. Using this API for querying the keypad status does not work in any of the S60 2nd Edition, S60 3rd Edition, and S60 3rd Edition, FP1 devices.

How to reproduce

TIndicatorPayload result;
 TInt status = MScreensaverPluginHost::GetIndicatorPayload (
                     EScreensaverIndicatorIndexKeyGuardState, result );
 // If result is other than '0', keylock is activated
 if (status == KErrNone && result.iInteger != 0)
      {
      // Draw key symbol
      }

Solution

A workaround is to query the keylock status with the RAknKeyLock method.

RAknKeyLock keyLock;
 if (keyLock.Connect() == KErrNone)
     {
     TBool locked = keyLock.IsKeyLockEnabled();
     if (locked)
         {
         // Draw key symbol
         }
     keyLock.Close();
     }
