currentTimestamp()

qint64 KisInputManager::Private::TabletLatencyTracker::currentTimestamp ( ) const

Returns

The timestamp of "right now" in a frame that is comparable to those timestamps given to push().

Implements KisLatencyTracker.

{
    // on OS X, we need to compute the timestamp that compares correctly against the native event timestamp,
    // which seems to be the msecs since system startup. On Linux with WinTab, we produce the timestamp that
    // we compare against ourselves in QWindowSystemInterface.
 
    QElapsedTimer elapsed;
    elapsed.start();
    return elapsed.msecsSinceReference();
}
