QML, dynamically adding elements to a listview

Question

I need some help with adding elements into a qml listview, i have a textarea and a button that will add the textarea text into a listview item when is pressed, here's my attempt:

Component {
    id: delegate
    Item {
        width: 200; height: 28
        Label {
            text: score
        }
    }
}

ListView {
     id: p1scores
     model: p1model
     delegate: delegate
     anchors.top: p1name.bottom
     anchors.topMargin: units.gu(1)
}

ListModel {
     id: p1model
     ListElement { score: "0" }
}

TextArea {
     id: p1input
     width: units.gu(8)
     height: units.gu(3)
     horizontalAlignment: TextEdit.AlignHCenter
     inputMethodHints: Qt.ImhDigitsOnly
     contentHeight: units.gu(60)
     anchors.topMargin: units.gu(8)
}

Button {
     id:p1button
     text: i18n.tr("Add")
     width: units.gu(8)
     onClicked: {
        p1model.append({"score": p1input.text})
        p1input.text = ""
     }
}

i tried appending it but doesn't shows up in the listview... any help?

in your p1button onClicked, you cleared the text in TextArea before adding the text to the ListModel, of course the text wouldn't show up. — Dickson

The text still doesn't shows up, i think its a problem with the delegate... (edited the question) — Hairo

I'm not sure but... change your delegate Component id to something else, because when you use delegate: delegate in your ListView, it assume is delegate: p1scores.delegate, so it bind back to itself. — Dickson

i found the problem, it was that i didn't specified a height to the listview and apparently the default is the size of a single item... — Hairo

Try without quotes around 'score', like this:

onClicked: {
    p1model.append({score: p1input.text})
    p1input.text = ""
}
