[Solved]Any example of StackView?

Qt5.2

Studying StackView but have no idea how to use it.

@
import QtQuick 2.2
import QtQuick.Controls 1.1

Rectangle {
id: root

width: 360
height: 360

Column{

    Button{
        width: root.width
        height: root.height / 10

        onClicked: {
            stackView.push({item:Rectangle, properties: {width: root.width, height: root.height}})
        }
    }

    StackView {
        id: stackView
        delegate: StackViewDelegate {
            function transitionFinished(properties)
            {
                properties.exitItem.opacity = 1
            }

            property Component pushTransition: StackViewTransition {
                PropertyAnimation {
                    target: enterItem
                    property: "opacity"
                    from: 0
                    to: 1
                }
                PropertyAnimation {
                    target: exitItem
                    property: "opacity"
                    from: 1
                    to: 0
                }
            }
        }
    }
}

}

Apparently, this wouldn't work
After I click the button, it pop out the error message

Error:Could not load: file///someaddress/[object Object]:-1 File not found

How could I push the component into the StackView properly?

I find an example by myself

If you know more examples of StackView, please show me, thanks.
