well, the problem is that createTree() does not registered in your
QObject-derived class. its a part of instantiated object ant metasystem
have no clue about it
I think you need to register it 1st in header somehow

Yes, that's what I'm doing, but I 'm typing the code in the mail -
sorry for the typo.
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();
}

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 ?
Thanks,
