Set the default pen for the contour lines. 
<p>
If the spectrogram has a valid default contour pen a contour line is painted using the default contour pen. Otherwise (pen.style() == Qt::NoPen) the pen is calculated for each contour level using <a class="el" href="class_qwt_plot_spectrogram.html#9c5c16fcda0422739c5393e42be5af37">contourPen()</a>.<p>
