Accessing element in a separated Listmodel file

Allon

Hi,
I do not manage to access a given element from a Listmodel located in a separated file.

What works is having the Listmodel inside the main file:

main.qml:

ListModel {
    id: taskData

    ListElement { name : "name1" }
    ListElement { name : "name2" }
}

Column {
    id: column
    Repeater {
        model: taskData
        Text { text: "I'm item " + taskData.get(1).name }
    }
}

It gives the following output:

I'm item name2
I'm item name2

What I do not manage to access an element if the Listmodel in an external file.

TaskData.qml

import QtQuick 2.0

ListModel {
    id: taskData

    property alias taskData: taskData

    ListElement { name : "name1" }
    ListElement { name : "name2" }
}

main.qml

Window {
    visible: true
    width: 200
    height: 300
 
    Column {
        id: column
        Repeater {
            model: TaskData {}
            Text { text: "I'm item " + taskData.get(1).name }
        }
    }
}

When running the second example I get
qrc:/main.qml:20: ReferenceError: taskData is not defined
qrc:/main.qml:20: ReferenceError: taskData is not defined

What should I do to be able to read taskData if it is present in an external file ?

Thanks in advance,
Emmanuel

@Allon just create TaskData item from your TaskData component :
in main.qml

Window {
    visible: true
    width: 200
    height: 300
 
    TaskData{
        id:taskData
    }

    Column {
        id: column
        Repeater {
            model: taskData
            Text { text: "I'm item " + name }
        }
    }
}

@Allon said in Accessing element in a separated Listmodel file:

Text { text: "I'm item " + taskData.get(1).name }

You don't need to provide an id and to to create a property for your listModel component,
try instead to access the listmodel data directly with its role :

Text { text: "I'm item " + name }

you can disambiguate a role name using modelData (i.e modelData.name).

@Charby Hi,
Is it not only the case when I am in the repeater?

In my example I skimmed a large project where I am getting an index from a mousearea drag and drop and I want to access the element pointed by this index.

Here is the original line of my program:

taskData.get(taskColumnRectangleIndex).tasks.insert(taskData.get(taskColumnRectangleIndex).tasks.count, {"description": "task number: " + taskData.get(taskColumnRectangleIndex).tasks.count, /"taskHovered": true/ color:"red"})

However in order to make the code a little bit more readable I wanted to move my Listmodel taskData out of the file I al coding in.

Do you have an idea how I could then access taskData if it is located in a separated file?

Thanks in advance,

Emmanuel

@Charby It works like a charm!
Thanks you very much, I have been trying to solve this problem since hours!
I would not have found it myself.
Thanks again,
Emmanuel
