[QML] Binding with dynamic type not compilable

XMLWordPrintable

    • All

      When using a Loader component combined with a bound property, the compiler claims that this is not compilable, spitting a couple of warnings/errors. So

      Loader {
    id: loader
    readonly property int foo: loader.item && loader.hasOwnProperty("bar") ? loader.item.bar : 0
}

      results in

      Warning: main.qml:12:94: Property "bar" not found on type "QObject"
        readonly property int foo: loader.item && loader.hasOwnProperty("bar") ? loader.item.bar : 0
                                                                                             ^^^
Error: main.qml:12:94: Could not compile binding for foo: Cannot load property bar from QObject of QQuickLoader::item with type QObject.
        readonly property int foo: loader.item && loader.hasOwnProperty("bar") ? loader.item.bar : 0
                                                                                             ^^^

      .

      Is there a cleaner way to do it? If there's none, how to get rid of the warning/error?
