title: signal qt from a non-qt thread, QueuedConnection
body: <p>I am signaling my Qt GUI thread from a boost::thread, and I am using a Qt::QueuedConnection,</p>
  
  <pre><code> connect(src, SIGNAL(signal-signature), dest, SLOT(slot-signature), Qt::QueuedConnection);
  </code></pre>
  
  <p>and still, when I emit the signal my slot does not get called.</p>
  
  <p>edit: I found the problem, it seems that I was connecting the signal later then my call, but I was sure of the otherwise since breakpoints stopped first on the GUI thread at the connect call and then on the dispatch thread that does the emit</p>
  
  <p>ty everybody for the help and ideas :D</p>
