Unable to call another qml class

[houmingc]

I am a self learn QML newbie.
Below is my code
currently i got 2 error i do not know how to resolve:
-Type Marquee unavailable
-module "QtQuick" version 1.0 is not installed.

My understanding is qml filename is like a C++ class.
When i call it in another qml file, it is instantiated.
Why error Marquee unavailable?

Another issue is i got problem importing QtQuick Particles 2.0 or any other modules. why?

--------------main.qml-----------------------

import QtQuick 2.2
import QtQuick.Controls 1.1

ApplicationWindow {
visible: true
width: 640
height: 480
title: qsTr("Hello World")

Marquee{               //error1
width: 640
padding: 2
anchors.bottom: parent.bottom
text: "i love you!"
color: "black"
textColor: "white"
}

}
--------------Marquee.qml-----------------------

import QtQuick 1.0 //error2

Rectangle {
width: parent.width
height: marqueeText.height + padding
clip: true

// text to be displayed by the Marquee
property string text

// top/bottom text padding
property int padding : 10

// the font size used by the Marquee
property int fontSize : 20

// the scrolling animation interval
property int interval : 100

// the text color
property color textColor: "black"

Text {

anchors.verticalCenter: parent.verticalCenter
id: marqueeText
font.pointSize: fontSize
color: textColor
text: parent.text
x: parent.width
}

Timer {

interval: parent.interval
onTriggered: moveMarquee()
running: true
repeat: true
}

function moveMarquee()
{

if(marqueeText.x + marqueeText.width < 0)
{
marqueeText.x = marqueeText.parent.width;
}
marqueeText.x -= 10;
}

}

Type Marquee is not available, because it contains an error - so the the engine cannot use it. Fix the error, and the component will work.

And the error is that you are mixing QtQuick 1 and 2, which are not compatible. Change the import in Marquee.qml to import QtQuick 2.2

Sorry, but you are not the original poster. Is that another account of yours?

[melghawi]

No, but it seems like it is solved so I was just simply asking the author to mark it as solved. I am sorry if I assumed incorrectly.

Ah, ok then, thank you. Let's wait for OP response, then.

-I might be wrong but shouldn't he also import Marquee.qml(or the folder which contains the file)?-

Nevermind, tested it out, it's not necessary in some circumstances.

[sierdzio]

Current folder is imported by default in QML.
