Hi and welcome to devnet,

Isn't the StackView Finding Items Chapter what you are looking for ?

Hi @mrbongdem
Also in addition to @SGaist's answer StackView too has a few attached properties and index is one of them. Check supported-attached-properties.

Thank you for your help !!!
I solved it by add property **index ** for each element in ListModel.

@mrbongdem Thats great. But how did you use ListModel with StackView ? You can directly get index using Stack.index inside the item without creating a new property.

Hi @p3c0
I use this way :

 StackView {
         id: stackView
         initialItem: ListView {
	     model: rssFeeds
		 delegate: Button{
	     onClicked: {
			// at here I take index .It is property of ListModel rssFeeds	
		 }
        }
	
      }
     }

And How do you use Stack.index .Can you give me example for it ?
Thank you for your replay.

@mrbongdem Ok so you have StackView which contains ListView in which you wanted index. I imagined something different from your original question.
Anyway ListView has index attached property. So no need of creating another index property. Eg.

ListView {
    model: ListModel {
        Component.onCompleted: {
            for(var a=10; a<15; a++)
                append( { name: "Item: " + a })
        }
    }
    delegate: Text {
        text: name + " with Index: " + index //index = attached property
    }
}
