- * CTapGestureRecogniser handles both tap and double tap recognition.
- * Doubletap needs to work even if it crosses window boundaries, so
- * CTapGestureRecogniser is a "global" recogniser. The application
- * creates only one instance of it (TODO later: how to use Singleton
- * pattern in Symbian, seems to be tricky since we would need to have
- * writable static variable to hold the one instance, so currently
- * we need well-behaving app to handle this: the application must known
- * the nature of this gesture recogniser).
- * The different windows can add their callbacks, and when recognising tap
- * the target window is stored so that proper callback can be called.
- * Doubletap is reported either to the target of second tap, or if that windows parent
- * has a doubletap listener, to that.
- * Use separate listeners for tap and doubletap.
