title: Register a Meta Type in Qt
body: <p>I have a class and I want to use it in a Qvariant, therefore I need to Declare and Register the Meta type. This is what I've done:</p>
  
  <pre><code>class blabla: public QThread
  {
     Q_OBJECT
   .
   .
   .
   };
   Q_DECLARE_METATYPE(blabla)
  </code></pre>
  
  <p>But this code is giving me Error:</p>
  
  <pre><code>In copy constructor ‘QThread::QThread(const QThread&amp;)’:
  instantiated from ‘void* qMetaTypeConstructHelper(const T*) [with T = blabla]’
  instantiated from ‘int qRegisterMetaType(const char*, T*) [with T = blabla]’
  instantiated from here
  ‘QObject::QObject(const QObject&amp;)’ is private
   within this context

  </code></pre>
  
  <p>I guess I need to register my met-type, but I am not sure where to have <code>qRegisterMetaType&lt;MyClass&gt;("MyClass");</code>. I tried having it after the meta type declaration macro, but resulted in error. Appriciate any comment or hint which directs me to the right path.</p>
