How to get list of all items in QML StackView that pushed into stack?

[bogong]

Hello!
I am trying to find something about getting list of all items in QML StackView that pushed into stack. Is there any option to get it?

@bogong hi use methodes https://doc.qt.io/qt-5/qml-qtquick-controls2-stackview.html#methods

You can use this function to list all items.

function listItems(){

            for(var i=0; i<stackView.children.length;i++)
            {
                var item = stackView.get(i);
                console.log(item.title);
            }
    }

@CKurdu Thx a lot ... Maybe you know how to avoid correctly creating duplicated object in stack? Is there in-box solution? For example if the page "settings" already existed and I don't want to create it again in stack but showing already existed. Is there kind of "singleton" for elements in the stack? Or killing existed in stack when leaving it?

I don't know in-box solution but you can solve your problem with the javascript file. First implement a javascript file like below

var dict = {};
var sv;
function setStackView(item)
{
    sv = item;
}
function push(id,item) {
    if(!dict.hasOwnProperty(id))
    {
        dict[id] = item;
        sv.push(item);
    }else{
        console.debug("dublicate!");
    }
}
function get(id)
{
    return dict[id];
}

function list()
{
    console.debug("list");
    var keys = Object.keys(dict);
    for(var i=0; i<keys.length; i++)
    {
        console.debug(keys[i]+ " : " + dict[keys[i]]);
    }
}

then you can import and use

import "StackController.js" as StackController
...
...
   Component.onCompleted: {
                    StackController.setStackView(stackView);
                    StackController.push("page2",page2)
                    StackController.push("page1",page2)
                    StackController.push("page1",page1)
                    StackController.list();
    }

But this code only works for item base not for the URL base.

@CKurdu Thx for reply. I am doing similar usually. I've been seeking something that in-box from pure QT without additional storing info about what in stack. Looks like nothing in it yet. First time I've been questioning about it about 4-5 years ago ...
