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.

The Qt Quick module provides the basic elements to specify and implement your user interface declaratively, using the Qt Meta-Object Language (QML). The Qt QML module provides the engine and language infrastructure for QML itself. This language is very expressive and human readable, and can be used by designers to actually implement their UI vision. QML UIs can integrate with C++ code in many ways, including being loaded as a part of a C++ UI and loading data models from C++ and interacting with them. Mostof these examples can be viewed directly with the QML viewer utility, without requiring compilation. Documentation for these examples can be found via the Examples link in the main Qt documentation.
