I have Foo class which is derived from QAbstractListModel. And Bar class which I register and create in qml. Bar class holds Foo object exposed as property.
class Foo : public QAbstractListModel { Q_OBJECT public: explicit Foo(QObject *parent = nullptr) : QAbstractListModel(parent) { mList.append("test1"); mList.append("test2"); mList.append("test3"); } virtual int rowCount(const QModelIndex &parent) const Q_DECL_OVERRIDE { return mList.count(); } virtual QVariant data(const QModelIndex &index, int role) const Q_DECL_OVERRIDE { return mList.at(index.row()); } private: QStringList mList; }; class Bar : public QQuickItem { Q_OBJECT Q_PROPERTY(Foo* foo READ foo NOTIFY fooChanged) public: explicit Bar(QQuickItem *parent = nullptr) : QQuickItem(parent) { mFoo = new Foo(this); } Foo *foo() const { return mFoo; } signals: void fooChanged(Foo *foo); private: Foo *mFoo; }; Register Bar type:
qmlRegisterType<Bar>("Custom", 1, 0, "Bar"); qml:
import QtQuick 2.6 import QtQuick.Window 2.2 import QtQuick.Controls 2.0 import Custom 1.0 Window { visible: true width: 640 height: 480 title: qsTr("Hello World") ListView { id: someList model: bar.foo delegate: Text { text: modelData } } Bar { id: bar } } I create ListView and assign model Foo. Expected result is to see delegate text filled with "test1", "test2", "test3" but I get this:
ReferenceError: modelData is not defined ReferenceError: modelData is not defined ReferenceError: modelData is not defined
