Ok Thanks From: Keith Gardner [mailto:kreios4...@gmail.com] Sent: 14 February 2014 15:21 To: Jason H Cc: Graham Labdon; interest@qt-project.org Subject: Re: [Interest] metaObject from class name
If you register the class with QMetaType with Q_DECLARE_METATYPE(Class*), you can then call QMetaType::type("Class"). With the returned int, you can then call QMetaType::metaObjectForType(integer). I think this is what you are looking for. class Foo : public QObject { ... }; Q_DECLARE_METATYPE(Foo*) const char *string = "Foo"; const QMetaObject* metaObject = QMetaType::metaObjectForType(QMetaType::type(string)); I haven't tried compiling this but I believe this is how it will work based off of the docs for QMetaType.

You can create any QObject through QMetaObject by the class name, then get the meta object for the created object. Look at QMetaObject::newInstance(..) You need a "class factory" design pattern.
