Accessing a child/item's property in Repeater

kwisatz

How do I access the text property of xText for various children/items (a,b,c)?

I'm able to initialize the property using the model, but what if I want to modify it after initialization or bind to it in C++?

@

property string a: "A"
property string b: "B"
property string c: "C"

Row {
id: xRow
anchors.centerIn: parent
visible: true
spacing: 5

        Repeater {
            id:xRepeater
            model: [a, b, c]

            Image {
                id:xImage
                width: 78; height: 70
                fillMode: Image.Stretch
                source: "imgs/x.png"
                smooth: true

                Text {
                    id: xText
                    anchors {centerIn: parent}
                    text: modelData
                    font {pixelSize: 36}
                    color: "black"
                }

            }//end of image

        }//end of repeater block

    }//end of of row block@

Hi,
For this you will need a dynamic model like ListModel or if you want to access from C++ a child class of QAbstractItemModel or a QList<QObject*>. I would recommend using QAbstractItemModel. With this kind of model, changes to the model will cause the repeater to update its content.

Thanks, I was thinking something along this lines. But was hoping to uses the qml model as is and just bind to property value by finding the object through the object tree.

Hi,
You can try something like this:
@
property list<QtObject> myModel: [
QtObject{text: "A"},
QtObject{text: "B"},
QtObject{text: "C"}
]

Row {
id: xRow
anchors.centerIn: parent
visible: true
spacing: 5

        Repeater {
            id:xRepeater
            model: myModel

            Image {
                id:xImage
                width: 78; height: 70
                fillMode: Image.Stretch
                source: "imgs/x.png"
                smooth: true

                Text {
                    id: xText
                    anchors {centerIn: parent}
                    text: modelData.text
                    font {pixelSize: 36}
                    color: "black"
                }

            }//end of image

        }//end of repeater block

    }//end of of row block

This way, changes in your object properties should cause binding reevaluation. However, I don't know how this would be mapped into C++. Probably a QList<QObject*> or a QVariantList but you will have to test this to be sure.
