It would be better to emit the whole pointer event (by pointer because it's non-copyable, or make it copyable and emit by value), but we can't. So we just add the button being tapped; more information is available from the eventpoint argument and TapHandler's point property. To avoid name clashes with anything that's already called "button" in anyone's QML (which is quite likely, actually), the new signal argument is unnamed, so that users will be required to write a function signature that gives it a name rather than relying on context injection. [ChangeLog][QtQuick][Event Handlers] TapHandler's tapped(), singleTapped() and doubleTapped() signals now have two arguments: the QEventPoint instance, and the button being tapped. If you need it, you should write an explicit function for the signal handler: onTapped: function(point, button) { ... } or onDoubleTapped: (point, button)=> ...
