Hi,
Instead of accessing the delegate directly, it's better to change it
through Model/View mechanism, using property bindings like below:
Item {
width: 400
height: 400
ListModel {
id: model
ListElement { color: "red" }
ListElement { color: "green" }
ListElement { color: "blue" }
}
Column {
Repeater {
model: model
Rectangle {
id: item
width: 50
height: 50
color: model.color
}
}
}
MouseArea {
anchors.fill: parent
onClicked: model.setProperty(1, "color", "gray");
}
}
Does it solve your problem?
Br,
Adriano
