Problem Accessing Views and Models from Delegates

[ariacorrente]

Hi all,
i have a problem when in a delegate i try to access data from the model or the view. I read the documentation at:

http://qt-project.org/doc/qt-4.8/qdeclarativemodels.html#accessing-views-and-models-from-delegates

I copied the following code in a new QML project and run in QtCreatore 2.4.1 with Qt 4.8:
@import QtQuick 1.1

Rectangle {
width: 200; height: 200

ListModel {
    id: fruitModel
    property string language: "en"
    ListElement {
        name: "Apple"
        cost: 2.45
    }
    ListElement {
        name: "Orange"
        cost: 3.25
    }
    ListElement {
        name: "Banana"
        cost: 1.95
    }
}

Component {
    id: fruitDelegate
    Row {
            Text { text: " Fruit: " + name; color: ListView.view.fruit_color }
            Text { text: " Cost: $" + cost }
            Text { text: " Language: " + ListView.view.model.language }
    }
}

ListView {
    property color fruit_color: "green"
    model: fruitModel
    delegate: fruitDelegate
    anchors.fill: parent
}

}@

The qml viewer displays the list but i get the following error:

bq. file:///[...].qml:28: TypeError: Result of expression 'ListView.view' [null] is not an object.
file:///[...].qml:26: TypeError: Result of expression 'ListView.view' [null] is not an object.

So, what i'm doing wrong?

Thanks for you time

Not sure why, but I think you cannot access ListView directly from within the Text element, you have to give the Row an id, e.g. delegate, and access ListView as delegate.ListView. Or just use parent.ListView.

Yes, you can. You just have to let it know where the view is. Try this!
@
Component {
id: fruitDelegate
Row {
id: wrapper
Text {
text: " Fruit: " + name
color: wrapper.ListView.view.fruit_color
}
// ... etc
}
}
