title: os.path.join() in Qt?
body: <p>I'm looking for an easy, cross platform way to join path, directory and file names into a complete path in C++. I know python has <code>os.path.join()</code> and matlab has <code>fullfile()</code>. Does Qt has something similar? <code>QFileInfo</code> doesn't seem to be able to do this.</p>
