Add TapHandler.exclusiveSignals to enable single/double tap exclusivity
If exclusiveSignals == NotExclusive (the default), behavior remains as
it was: singleTapped() and doubleTapped() are emitted as the taps occur,
so it's not very useful to react on singleTapped() if you mean to
distinguish these two cases.
If exclusiveSignals == SingleTap, the doubleTapped signal will not be
emitted at all, and therefore singleTapped can be emitted immediately
and unambiguously.
If exclusiveSignals == DoubleTap, the singleTapped signal will not be
emitted at all, and therefore doubleTapped can be emitted immediately
and unambiguously.
If exclusiveSignals == SingleTap | DoubleTap, we must wait
qApp->styleHints()->mouseDoubleClickInterval() milliseconds after a tap
is detected before emitting either signal, so that they are distinct and
can be used to drive behavior that should not occur in other cases.
A triple-tap will not trigger either signal.
[ChangeLog][QtQuick][Event Handlers] TapHandler.exclusiveSignals now
lets you make the singleTapped and doubleTapped signals exclusive.
