Description
Its public methods use QQmlV4Function and QJSValue as parameters or return values, which makes them uncompilable. Example at https://github.com/qt/qtdeclarative/blob/v6.5.2/src/qmlmodels/qqmllistmodel_p.h#L68-L72 :
Q_INVOKABLE void remove(QQmlV4Function *args); Q_INVOKABLE void append(QQmlV4Function *args); Q_INVOKABLE void insert(QQmlV4Function *args); Q_INVOKABLE QJSValue get(int index) const; Q_INVOKABLE void set(int index, const QJSValue &value);
Code
Adapted from https://doc.qt.io/qt-6/qml-qtquick-controls-combobox.html#accepted-signal
ComboBox {
model: ListModel {
id: model
ListElement { text: "Apple" }
ListElement { text: "Banana" }
ListElement { text: "Coconut" }
}
Component.onCompleted: console.log("First fruit is", model.get(0).text)
}
qmlsc output
Warning: Main.qml:16:69: Could not compile binding for onCompleted: Cannot generate efficient code for lookup in QJSValue [compiler]
Component.onCompleted: console.log("First fruit is", model.get(0).text)
