[Interest] QML objects and QMetaMethod

[Jean-Michaël Celerier]

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();
    }
