I'm working on a qml plugin in which I register a QObject-derived type for use within qml. I've set the default property on this item to be a QQmlListProperty<(other qobject derived type)>, and I've setup a READ function for this property. For some reason the qml engine will not load my application, complaining that this default property is read-only.
I understand you typically have to define a WRITE function in order to make properties writeable from qml, but the example that comes with Qt regarding default properties does not do this, and it compiles fine: http://qt-project.org/doc/qt-5/qtqml-referenceexamples-default-example.html Here's the class definition I'm using: class DefaultContent : public QObject { Q_OBJECT Q_PROPERTY(QQmlListProperty<ShareableItem> attachments READ attachments) Q_CLASSINFO("DefaultProperty", "attachments") public: explicit DefaultContent(QObject* parent = 0); QQmlListProperty<ShareableItem> attachments(); signals: public slots: private: QList<ShareableItem*> m_attachments; }; And the qml... import QtQuick.2.2 import QtQuick.Window 2.1 import Qtino.SharingKit 1.0 //This is my plugin that registers 'DefaultContent' Window { DefaultContent { id: defaultContentItem ImageItem { source: rootScreenGrab.url } } } The error I get is "Invalid property assignment: "attachments" is a read-only property" Am I doing something obviously wrong here? If I absolutely must have a WRITE method on this property, how would that work with a QQmlListProperty type if the backing model is a QList? Would the list be owned by js or cpp? And how is that the provided Qt example can work without a WRITE method? Any help would be much appreciated, Brian
