172 \brief Enables simple pinch gesture handling. -

173 -

174 \b {The PinchArea type was added in QtQuick 1.1} -

175 -

176 A PinchArea is an invisible item that is typically used in conjunction with -

177 a visible item in order to provide pinch gesture handling for that item. -

178 -

179 The \l enabled property is used to enable and disable pinch handling for -

180 the proxied item. When disabled, the pinch area becomes transparent to -

181 mouse/touch events. -

182 -

183 PinchArea can be used in two ways: -

184 -

185 \list -

186 \li setting a \c pinch.target to provide automatic interaction with an item -

187 \li using the onPinchStarted, onPinchUpdated and onPinchFinished handlers -

188 \endlist -

189 -

190 Since Qt 5.5, PinchArea can react to native pinch gesture events from the -

191 operating system if available; otherwise it reacts only to touch events. -

192 -

193 \sa PinchEvent, QNativeGestureEvent, QTouchEvent -

194 */ -

195 -

196 /*! -

197 \qmlsignal QtQuick::PinchArea::pinchStarted() -

198 -

199 This signal is emitted when the pinch area detects that a pinch gesture has -

200 started: two touch points (fingers) have been detected, and they have moved -

201 beyond the \l {QStyleHints}{startDragDistance} threshold for the gesture to begin. -

202 -

203 The \l {PinchEvent}{pinch} parameter (not the same as the \l {PinchArea}{pinch} -

204 property) provides information about the pinch gesture, including the scale, -

205 center and angle of the pinch. At the time of the \c pinchStarted signal, -

206 these values are reset to the default values, regardless of the results -

207 from previous gestures: pinch.scale will be \c 1.0 and pinch.rotation will be \c 0.0. -

208 As the gesture progresses, \l pinchUpdated will report the deviation from those -

209 defaults. -

210 -

211 To ignore this gesture set the \c pinch.accepted property to false. The gesture -

212 will be canceled and no further events will be sent. -

213 -

214 The corresponding handler is \c onPinchStarted. -

215 */ -

216 -

217 /*! -

218 \qmlsignal QtQuick::PinchArea::pinchUpdated() -

219 -

220 This signal is emitted when the pinch area detects that a pinch gesture has changed. -

221 -

222 The \l {PinchEvent}{pinch} parameter provides information about the pinch -

223 gesture, including the scale, center and angle of the pinch. These values -

224 reflect changes only since the beginning of the current gesture, and -

225 therefore are not limited by the minimum and maximum limits in the -

226 \l {PinchArea}{pinch} property. -

227 -

228 The corresponding handler is \c onPinchUpdated. -

235 -

236 The \l {PinchEvent}{pinch} parameter (not the same as the \l {PinchArea}{pinch} -

237 property) provides information about the pinch gesture, including the -

238 scale, center and angle of the pinch. -

239 -

240 The corresponding handler is \c onPinchFinished. -

242 -

243 /*! -

244 \qmlsignal QtQuick::PinchArea::smartZoom() -

245 \since 5.5 -

246 -

247 This signal is emitted when the pinch area detects the smart zoom gesture. -

248 This gesture occurs only on certain operating systems such as \macos. -

249 -

250 The \l {PinchEvent}{pinch} parameter provides information about the pinch -

251 gesture, including the location where the gesture occurred. \c pinch.scale -

252 will be greater than zero when the gesture indicates that the user wishes to -

253 enter smart zoom, and zero when exiting (even though typically the same gesture -

254 is used to toggle between the two states). -

255 -

256 The corresponding handler is \c onSmartZoom. -
