<hr><a name="_details"></a><h2>Detailed Description</h2>
The Knob Widget.
<p>
The <a class="el" href="class_qwt_knob.html" title="The Knob Widget.">QwtKnob</a> widget imitates look and behaviour of a volume knob on a radio. It contains a scale around the knob which is set up automatically or can be configured manually (see <a class="el" href="class_qwt_abstract_scale.html" title="An abstract base class for classes containing a scale.">QwtAbstractScale</a>). Automatic scrolling is enabled when the user presses a mouse button on the scale. For a description of signals, slots and other members, see <a class="el" href="class_qwt_abstract_slider.html" title="An abstract base class for slider widgets.">QwtAbstractSlider</a>.<p>
