ListView with ObjectModel and custom objects get index of selected object

[Aapje06]

Hello!

Is it possible to get the index of the selected item in an ObjectModel that is displayed with an ListView?

For example:

// A.qml

Item {
id: itemA
property string name;
Text {
text: "A:" + name
}
}

// B.qml

Item {
id: itemB
property string name;
Text {
text: "B:" + name
}
}


//List.qml

ListView {
property var objects;
id: listViewExample
model: objects
}


// main.qml

List {
objects: ObjectModel {
A { name: "test"}
B { name: "test"}
}
}

The reason is that i want to create multiple objects that can be displayed on one list, but each of them have a slightly different behaviour when clicked etc. This is a bit oversimplyfied here in this example.

However, the question remains. How can I get the index of the object in the components A and B in the custom implementation in files A.qml and B.qml. Note: the objects A and B should only be used in combo with the custom listview in List.qml (that is the goal at least)

Or from another perspective, how do I implement this cleanly to have a set of custom components in a list that notifies the above Listview when the custom component is clicked? The listview is displayed on a touchscreen that will scroll trough the list of items. And I want it to scroll to the selected item when selected.

I don't know why it doesn't say in the ListView docs, but you can use the "index" variable inside a delegate. I would assume you could use that in your A or B object inside an ObjectModel. I know you can use "index" inside a regular delegate.

I stumpled across this thread.
The answer is quite simple:

Item {
   id: itemA
   property string name;

   Text {
       text: "A: name:" + itemA.name + " index:" + itemA.ObjectModel.index;
   }
}
