Using get() and setProperty() should both work. However, some bugs were fixed
in ListModel recently relating to setting properties via these methods, so it's
possible that you were seeing these issues.
The following code works fine with the latest source:
ListView {
width: 200; height: 200
model: ListModel {
id: tagColumnModel
ListElement { tagName: "apple"; tagState: "" }
ListElement { tagName: "pear"; tagState: "" }
}
delegate: Rectangle {
id: rect
width: 200; height: 80
Text { text: tagName }
state: tagState
states: State {
name: "blah"
PropertyChanges { target: rect; color: "red" }
}
}
Component.onCompleted: {
tagColumnModel.get(0).tagState = "blah";
}
}
regards,
Bea
