QDeclarativeItem not changing colors when event is fired in QML

[hkenn124]

Hi,

I defined a QML file that changes the color of a mousearea's parent when it is clicked (based off of the sample from the documentation). For some reason, the color change that is suppose to happen never happens. The application that I am creating is not a pure QML app (works in that scenario). Instead, I have a qt application with a qgraphicsscene. I am loading the qml as a QdeclarativeItem and adding it into the scene. Does anyone know what I am doing wrong?

Thanks.

QT code:

QGraphicsScene* test = new QGraphicsScene();
    QDeclarativeEngine engine;
 
    QDeclarativeComponent component(&engine, QUrl("qrc:/qml/test.qml"));
 
    QDeclarativeItem *item = qobject_cast<QDeclarativeItem *>(component.create());
 
    qDebug() << component.errors();
    test->addItem(item);
    designWidget.graphicsView->setScene(test);

QGraphicsScene* test = new QGraphicsScene();
    QDeclarativeEngine engine;

    QDeclarativeComponent component(&engine, QUrl("qrc:/qml/test.qml"));

    QDeclarativeItem *item = qobject_cast<QDeclarativeItem *>(component.create());

    qDebug() << component.errors();
    test->addItem(item);
    designWidget.graphicsView->setScene(test);

QML:

import QtQuick 1.0

Rectangle {
    id: container
    width: 600; height: 200
 
    Rectangle {
        id: rect
        width: 50; height: 50
        color: "red"
        opacity: (600.0 - rect.x) / 600
 
        MouseArea {
            anchors.fill: parent
            drag.target: rect
            drag.axis: Drag.XandYAxis
            drag.minimumX: 0
            drag.maximumX: container.width - rect.width
            drag.minimumY: 0
            drag.maximumY: container.height - rect.height
 
            acceptedButtons: Qt.LeftButton | Qt.RightButton
            onClicked: {
                parent.color = "blue"
            }
 
        }
    }
}

Rectangle {
    id: container
    width: 600; height: 200

    Rectangle {
        id: rect
        width: 50; height: 50
        color: "red"
        opacity: (600.0 - rect.x) / 600

        MouseArea {
            anchors.fill: parent
            drag.target: rect
            drag.axis: Drag.XandYAxis
            drag.minimumX: 0
            drag.maximumX: container.width - rect.width
            drag.minimumY: 0
            drag.maximumY: container.height - rect.height

            acceptedButtons: Qt.LeftButton | Qt.RightButton
            onClicked: {
                parent.color = "blue"
            }

        }
    }
}

Doesn't the engine go out of scope when you leave the method?

Thanks. That was it. I really am a newb I guess that is what I get for cutting and pasting.

Thanks Again!
