A QSensorGesture object will take a list of one or more + recognizer ids in it's constructor. + + \snippet sensorgestures/mainwindow.cpp 1 + + and later stop the detection process. + + \snippet sensorgestures/mainwindow.cpp 2 + + The QSensorGesture object will contain all the signals of the valid requested recognizers found on the system. + + You can discover which of the requested recognizer ID's that were not found by using QSensorGesture::invalidIds(); + + By using QSensorGesture::gestureSignals(), you can get a QStringList of usable signals. + + +*/ |
