<p>A dial contains a scale and a needle indicating the current value of the dial. Depending on Mode one of them is fixed and the other is rotating. If not <a class="el" href="class_qwt_abstract_slider.html#a040fd1fd03592c524314bf4b5539608d">isReadOnly()</a> the dial can be rotated by dragging the mouse or using keyboard inputs (see <a class="el" href="class_qwt_dial.html#a61a2341a76abc20ea5bd72a0485be136">keyPressEvent()</a>). A dial might be wrapping, what means a rotation below/above one limit continues on the other limit (f.e compass). The scale might cover any arc of the dial, its values are related to the <a class="el" href="class_qwt_dial.html#a5d7a8b9094bcc3fb82b31c3ac9ad706d">origin()</a> of the dial.</p>
<p>Qwt is missing a set of good looking needles (<a class="el" href="class_qwt_dial_needle.html" title="Base class for needles that can be used in a QwtDial.">QwtDialNeedle</a>). Contributions are very welcome.</p>
