weird. it would be nice to see whole code snippet if possible

It also works if I remove Q_OBJECT from my C++ type: namespace lib { class MyObject : public QObject { }; } qmlRegisterType<lib::MyObject>("MyLib", 1, 0, "MyObject"); works as expected, but if I add Q_OBJECT in class MyObject : public QObject { }; then it does not work anymore ------- Jean-Michaël Celerier http://www.jcelerier.nameOn Sun, Oct 7, 2018 at 11:07 PM Jean-Michaël Celerier <jeanmichael.celer...@gmail.com <mailto:jeanmichael.celer...@gmail.com>> wrote:> well, the problem is that createTree() does not registered in your QObject-derived class. but why does it work in the following case then ?

Here's something even more fundamental : the following prints all the functions if my type is a QtObject descendant, but it does not if my type is a MyLib.MyObject descendant for(int i = 0; i < obj->metaObject()->methodCount(); i++) { qDebug() << obj->metaObject()->method(i).name(); } ------- Jean-Michaël Celerier http://www.jcelerier.name On Sun, Oct 7, 2018 at 12:39 PM Vlad Stelmahovsky <vladstelmahov...@gmail.com <mailto:vladstelmahov...@gmail.com>> wrote: QMetaMethod::invokeMethod(obj, "createTree"); On 10/7/18 12:34 PM, Jean-Michaël Celerier wrote:Hello, I have the following code : Foo.qml : MyLib.MyObject { function createTree() { /* stuff */ } property string host: "ws://whatever.com <http://whatever.com>" } cpp : namespace lib { class MyObject : public QObject { Q_OBJECT }; } ... QQmlComponent c(engine); c.setData("content of Foo.qml", QUrl()); auto obj = c.createObject(); QString host = QQmlProperty(obj, "host").read(); QMetaMethod::invokeMethod("createTree"); Reading the "host" property works fine so the QML object is correctly instantiated. But the invokeMethod call gives me a warning : QMetaObject::invokeMethod: No such method 'lib::MyObject::createTree()' The weird thing being: it works fine if I replace MyLib.MyObject with QtObject on the QML side. Of course I want to use some additional methods present in MyObject so this is not a solution. Anyone knows what is going on here ?
