How to Identify an Item which i am going to push in stackview is already existed in stackview's stack ?

divaindie

Hi All,
assume that i have multiple "page" items and a "StackView" as shown below.
i want to achieve something like , if i have already pushed 'page1' and if i have to push it one more time i have to search weather this particular 'page' already existed in the "StackView" tree ,if it is there i want to make that particular Item as top item in "StackView",if it is not there i will push that particular "page"
How i can achieve this ??

Component{
      id:page1
      Page{........}
}
Component{
      id:page2
      Page{........}
}
Component{
      id:page3
      Page{........}
}
StackView
{
id:sv
initialItem: page1

}

achieve

ApplicationWindow {
    id: window
    visible: true
    width: 600
    height: 200
    Component{
        id:page1
        Rectangle{
            color: "red"
        }
    }
    Component{
        id:page2
        Rectangle{
            color: "green"
        }
    }
    Component{
        id:page3
        Rectangle{
            color:"blue"
        }
    }
    property variant  pages : [page1,page2,page3]

    function setMenu(ind){
        sv.push(pages[ind])
    }

    RowLayout{
        id:menuLayout
        Repeater{
            model: pages.length
            Button{
                text: "menu " + index
                onClicked: {
                    setMenu(index)
                }
            }
        }
    }

    StackView
    {
        id:sv
        initialItem: page1
        anchors{
            top : menuLayout.bottom
