[Qt-qml] aliasing property of a delegate in a listview

[michael.brasser at nokia.com]

Hi,

The ListView's delegate is really just a template for the list items that will be shown in the view (as Girish pointed out in an earlier thread, delegate: aCustomDelegate {} is really just shorthand for delegate: Component { aCustomDelegate {} }), which is why you cannot create an alias to it (it will be instantiated many times). Are you looking for access to the data of the currently selected item in the view (i.e. the ListView's currentItem)? You could try something like the following if you don't need true aliasing:

 ListView {
    id: listview
    property string text: listview.currentItem ? listview.currentItem.text : ""
    delegate: Text {
            id: myDelegate
            text: sometext
    }
}

Regards,
Michael

I would like to export the properties of the delegate of a listview to make it more reusable. In other words, I would like to do something like this


ListView {

    id: listview

    property alias text: myDelegate.text


    delegate: aCustomDelegate {

            id:myDelegate

            text: sometext

    }

}


Is it possible?


Thanks,
