title: Vertical QLabel, or the equivalent?
body: <p>I want axis labels for a plot I'm making, and naturally the y-axis label should be oriented vertically.  I'm pretty sure <code>QwtPlot</code> does this, but I'm trying to keep things light so I'm just using a simple <code>QWidget</code> + <code>QPainter</code> for now.  I didn't see any way to change <code>QLabel</code> orientation in the documentation.  Some solutions are given in <a href="http://lists.trolltech.com/qt-interest/2002-09/msg00357.html" rel="noreferrer">this 2002 thread</a> but I'd like something that doesn't seem like such a hack.  I'm using Qt 4.8 now, is there really no way to do this aside from <code>QPainter::drawText()</code>?</p>
