Qt6 QML QQmlApplicationEngine failed to load component error

Habib123

I want to use component in QtQuick, i have two qml files one is main.qml and the second button.qml, and iam using this example for their documentation, but when i run my code it is giving me error that QQmlApplicationEngine failed to load component qrc:/bbb/main.qml:13:5: Button is not a type. also iam seeing some red error in the imported Button in main.qml. even i have removed the signal functionalities and i have just used the simple button, but again the same error, and also the same example with same structure works in qt5, but in qt6 it is not working.

main.qml

import QtQuick

    Window {
        id:root
         width: 640
         height: 480
         visible: true
         title: qsTr("Hello World")
    
    
        Button { // our Button component
            id: button
            x: 12; y: 12
            text: "Start"
            onClicked: {
                status.text = "Button clicked!"
            }
        }
    
        Text { // text changes when button was clicked
            id: status
            x: 12; y: 76
            width: 116; height: 26
            text: "waiting ..."
            horizontalAlignment: Text.AlignHCenter
        }
    
    }

Button.qml

import QtQuick 2.0

Item {
    Rectangle {
        id: root
        // export button properties
        property alias text: label.text
        signal clicked

        width: 116; height: 26
        color: "lightsteelblue"
        border.color: "slategrey"

        Text {
            id: label
            anchors.centerIn: parent
            text: "Start"
        }
        MouseArea {
            anchors.fill: parent
            onClicked: {
                root.clicked()
            }
        }
    }

}

main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>


int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    const QUrl url(u"qrc:/bbb/main.qml"_qs);
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                     &app, [url](QObject *obj, const QUrl &objUrl) {
        if (!obj && url == objUrl)
            QCoreApplication::exit(-1);
    }, Qt::QueuedConnection);
    engine.load(url);

    return app.exec();
}
