      import Qt 4.7

Rectangle {
    width: 200
    height: 200

    MouseArea {
        anchors.fill: parent
        onPressed: console.log("pressed")
        onMousePositionChanged: console.log("move")
        onReleased: console.log("released")
        onDoubleClicked: console.log("double clicked")
    }
}

      The above QML code generates this sequence of events 

      pressed
move
released
double clicked

      As you can can clearly see that sequence is missing a "released" event.

      For example, with Qt/C++ the following code

      class DoubleClickMe : public QWidget
{
    virtual void mouseDoubleClickEvent(QMouseEvent *) { qDebug() << "double click"; }
    virtual void mousePressEvent(QMouseEvent *) { qDebug() << "pressed"; }
    virtual void mouseMoveEvent(QMouseEvent *) { qDebug() << "moved"; }
    virtual void mouseReleaseEvent(QMouseEvent *) { qDebug() << "released"; }
};

      generates

      pressed 
released 
double click 
released
