    Description

      With the following code:

      Rectangle {
    id: rectangle

    implicitWidth: 200
    implicitHeight: 200
    color: "#FFE082"

    Text {
        anchors.centerIn: parent
        text: "Pressed: %1, Time held: %2".arg(tapHandler.pressed).arg(tapHandler.timeHeld)
    }

    TapHandler {
        id: tapHandler

        onTapped: console.debug("onTapped")
        onSingleTapped: console.debug("onSingleTapped")
        onDoubleTapped: console.debug("onDoubleTapped")
        onLongPressed: console.debug("onLongPressed")
        onCanceled: console.debug("onCanceled")
    }
}

      after 3 light fast taps (without really pressing of the touchpad) signal longPressed will be emitted. TapHandler stays in this state for some time and does not respond to clicks with mouse, touchpad or touch with touch screen
