<h1 align="center">Implicitly and Explicitly Shared Classes</h1><br clear="all">
<p>
These classes are normally-heavy classes which in Qt have been
optimized by the use of reference counter and common data so they can
be passed around.
<p>
The only important effect is that the classes listed here <em>can</em>
be passed around as arguments, even though they may seem heavyweight.
<p>Classes:<ul plain>
