title: scalability of pythonqt for millions of objects
body: <p>I was thinking about adding pythonqt to my application for writing plugins.  My application is in C++ and already uses the Qt framework.  The pythonqt option seems like a natural fit for adding GUI components, but I'm concerned about how well the program will scale if I expose an class with millions of instances.  It will not be uncommon to have something like a million of a certain type of object in memory and I wanted to make sure pythonqt would be able to expose these objects without making them QObjects.  It may be fine, I guess, but before I started, I was wondering if exposing such a large number of classes would be practical using pythonqt and if anyone had any experience with scaling it this much.  </p>
  
  <p>From this link (http://pythonqt.sourceforge.net/Developer.html), it seems the decorators actually only load them into python/Qt on request.  I just don't want an even bigger memory footprint of Qt trying to keep track of these millions of objects for no reason.  </p>
