Custom QML Properties

Question

I am having trouble defining a custom property in a QML element:

Item {
    property MovieTileItem data
    Text {
        text: "Some text"
    }
}

MovieTitleItem is an element defined in a separate QML file:

import Qt 4.7

Item {
    property string title
    property string posterSource
}

The error I get is "Unable to assign property" by specifying a property declaration. Any ideas?

Answer 1

“Unable to assign object to property” because a property such as “data” already exists (and it is read-only):

Answer 2

, , qmlRegisterType(). , , , , .

Item {
    data:Custom{}
    Text {
        text: "Some text"
    }
}
