Impossible Qt quick application from Ray Rischpater's book

Hi all. At first no quick application possible. You told me to install qtdeclarative5-dev and qml-module-qtqick2. I did that. I have now Qtquick but I have a problem with my first code. Look please at line 9. Here is the code:

Code:

---

import QtQuick 2.5
import QtQuick.Window 2.2
 
Window {
    visible: true
    width: 360
    height: 360
 
    MouseArea {
        anchors.fill: parent
        onCliqued: {//Cannot assign to non-existent property "onCliqued"
            Qt.quit();
        }
    }
 
    Text {
        id: text
        text: qsTr("Hello World")
        anchors.centerIn: parent
    }
 
    Rectangle {
        id: rectangle1
        x: 135
        y: 50
        width: 100
        height: 100
        color: "#ffff22"
 
        MouseArea {
            id: mouseArea1
            anchors.fill: parent
            onClicked: text.text = qsTr("Hi there ! ")
        }
    }
}

I dont find how to tag the above code. Sorry. Look please at the commented line. Thanks

MouseArea has no signal named "cliqued" so there is no signal handler "onCliqued"

I would have assumed that you wanted to handle the "clicked" signal, but you do that later on so I am not sure which signal you are looking for here.

Cheers,

I deleted all about first MouseArea, and now everything is OK. Thank you very much. But how is it possible there is such a big error in the book ?? The error is on page 19 of the book "Application Development with Qt Creator. Second Edition".
