You can set the time for the long-tap animation to start after the stylus has been set down on a control. Use the method SetTimeDelayBeforeAnimation for changing the time setting.
If not set, then default value (0.15 seconds) will be used. The time is set in microseconds.
TInt time ( 500000 ); // 0.5 seconds iLongTapDetector->SetTimeDelayBeforeAnimation ( time );
