ListView: using external model?

[mzimmers]

Hi all -

I've created a component (most stuff deleted):

Rectangle {
    ListModel {
        id: activityModel
        ListElement { parameter: "Capacity" }
        ListElement { parameter: "Speed" }
        ListElement { parameter: "Speed limits" }
    }

    Component {
        id: activityDelegate
        Text {
            id: paramName
            text: model.parameter
        }
    }

    ListView {
        id: activityView
        model: activityModel
        delegate: activityDelegate
    }
}

I'd like to remove the model from this component, and furnish from the instantiator. I assume this is possible; how best to go about it?

Thanks...

Rectangle {
    property alias model: activityView.model

    Component {
        id: activityDelegate
        Text {
            id: paramName
            text: model.parameter
        }
    }

    ListView {
        id: activityView
        delegate: activityDelegate
    }
}

@fcarney that's pretty slick. Alias properties are fairly powerful, aren't they?

Thanks for the help...

@mzimmers Happy New Year!

OK, I feel really silly asking this, because I'm the one who introduced it into this topic, but...where can I find documentation on what this line does:

text: model.parameter

Thanks...

Note that you can now use required properties instead. Be careful that having a delegate with any required property will prevent you from using implicit context properties (like the model.parameter here) like before, you can't mix and match.
