How to use addItem method of SplitView ?

[Tucky]

Dear All,

I want to add an Item to a splitview on some event. I took the SplitView example from the documentation and added a MouseArea which call the addItem method with a Rectangle item. The problem is that I get an error message like:
split.qml:71 Expected token `)' which correspond to the line splitview.addItem( Rectangle { Text { text: "new" } } )
I don't understand what happens. Here is my code:

import QtQuick 2.5
import QtQuick.Controls 1.4
import QtQuick.Layouts 1.1

SplitView {

    id: splitview

    width: 800
    height: 800
    orientation: Qt.Horizontal

    Rectangle {
        width: 200
        Layout.maximumWidth: 400
        color: "lightblue"
        Text {
            text: "View 1"
            anchors.centerIn: parent
        }
    }
    Rectangle {
        id: centerItem
        Layout.minimumWidth: 50
        Layout.fillWidth: true
        color: "lightgray"
        Text {
            text: "View 2"
            anchors.centerIn: parent
        }
        MouseArea {
            anchors.fill: parent
            onClicked: {
                splitview.addItem( Rectangle { Text { text: "new" } } )
            }
        }
    }
    Rectangle {
        width: 200
        color: "lightgreen"
        Text {
            text: "View 3"
            anchors.centerIn: parent
        }
    }
}

Hi and welcome to devnet,

From what I've gathered, it should be something like

Component {
   id: itemToAdd
   Rectangle {
       Text {
            text: "new"
       }
   }
}

Rectangle {
        id: centerItem
//your code
    onClicked: {
        var newItem = itemToAdd.createObject()
        splitView.addItem(newItem)
    }
}

Hope it helps

Thanks, it helps indeed.
You gave a solution, now for the explanation, if I understand correctly it’s you have to use the createObject method when you are in a javascritpt part.

It's not because of the javascript part. createObject is used to create new objects dynamically the way you want it. What you where doing is declaring a Rectangle not instantiating a new one when calling addItem.
