problem with ListView

[cosmoff]

Hello everybody,

I have in a QQmlListProperty (firstQml) an other QQmlListProperty (secondQml), so in the main.qml I have :

FirstQQml{
	ListView{
		model : firstqmlList // it is a list of name and there is the second QQmlListproperty

		delegate: persoButton{
			Text{ text: name}
		}
	}
}

SecondQQml{
	 ListView{
	 	model : firstqmlList

	 	delegate: ListView{
	 		model : secondQmlList // it is a list of number

	 		delegate: Text{
	 			text : number
	 		}
	 	}
	 }
}

It works, but when I click on my list of persoButton, it doesn't change the number bound to name. How can I do that ?

I hope you understood my problem

thanks a lot.

Is it not possible to do what I want to do ?

@cosmoff can you be more specific with what you want to happen, I can't quite follow.

[cosmoff]

for example :
I have a serie of name in the firstQQml

paul
sam
luc
jordan
mike

and in the secondQQml, I have a list of number

10
5
6

this numbers 10-5-6 are bound at the name paul. and the numbers 1-25-3 are bound at the name sam. But when I click on the name sam the numbers don't change.

When I change of name by clicking on the name sam, I would like change the display of number in the second ListView

@cosmoff
you mean, something like this ?

import QtQuick 2.12
import QtQuick.Controls 2.5

ApplicationWindow {
  visible:true
  width:500; height:500



    ListView{
        id: view1

        model: ["Paul", "Franz", "Karl"]

        anchors.left: parent.left
        anchors.right: parent.horizontalCenter
        anchors.top: parent.top
        anchors.bottom: parent.bottom

        delegate: Button{
            text: modelData
            onClicked:{
                console.log("clicked",text)
                view2.newModel(index)
            }
        }
    }

    ListView{
        id: view2

        model: [1, 2, 3]

        function newModel( index){

            switch(index){
            default:
            case 0: view2.model = [1,2,3]; break;
            case 1: view2.model = [4,5,6];break;
            case 2: view2.model = [7,8,9];break;
            }
        }

        anchors.right: parent.right
        anchors.left: parent.horizontalCenter
        anchors.top: parent.top
        anchors.bottom: parent.bottom

        delegate: Text{
            text: modelData
        }
    }
}

@J.Hilk yes exactly ! but how can I have the same result with the code in my main.qml ?

[J.Hilk]

@cosmoff
well you'll have to adapt my example.

The key is, that the model of SecondQQml is changed when you click on the button on your first ListView

[cosmoff]

I am totally lost, how can I do that, because my model is a QQmlListProperty

[cosmoff]

ok I understood thanks for your help
