61 \brief Handler for pinch gestures.-
62-
63 PinchHandler is a handler that interprets a multi-finger gesture to-
64 interactively rotate, zoom, and drag an Item. Like other Pointer Handlers,-
65 by default it is fully functional, and manipulates its \l target,-
66 which is the Item within which it is declared.-
67-
68 \snippet pointerHandlers/pinchHandler.qml 0-
69-
70 It has properties to restrict the range of dragging, rotation, and zoom.-
71-
72 If it is declared within one Item but is assigned a different \l target, it-
73 handles events within the bounds of the outer Item but manipulates the-
74 \c target Item instead:-
75-
76 \snippet pointerHandlers/pinchHandlerDifferentTarget.qml 0-
77-
78 A third way to use it is to set \l target to \c null and react to property-
79 changes in some other way:-
