Access Listview currentIndex from Delegate

Question

I have a QML ListView where the delegate loads it\'s component from another file. When clicking on an delegate item, I want to update ListView. C

Answer 1

There are two problems here:

• You need to qualify ListView's attached properties with the name of the item from which they're accessed.
• The currentIndex property is a property of the ListView item type, not the attached property object.

To fix them both, first change this:

ListView.currentIndex = index;

to this:

delegate.ListView.view.currentIndex = index;

And then give your delegate an id:

Component {
    id: contact

    Rectangle {
        id: delegate
    // ...
}

This is demonstrated (in part) by the Example Usage section of the documentation:

ListView attaches a number of properties to the root item of the delegate, for example ListView:isCurrentItem. In the following example, the root delegate item can access this attached property directly as ListView.isCurrentItem, while the child contactInfo object must refer to this property as wrapper.ListView.isCurrentItem.
