<div class="textblock"><p>The Knob Widget. </p>
<p>The <a class="el" href="class_qwt_knob.html" title="The Knob Widget.">QwtKnob</a> widget imitates look and behavior of a volume knob on a radio. It looks similar to QDial - not to <a class="el" href="class_qwt_dial.html" title="QwtDial class provides a rounded range control.">QwtDial</a>.</p>
<p>The value range of a knob might be divided into several turns.</p>
<p>The layout of the knob depends on the <a class="el" href="class_qwt_knob.html#a602b71c9be4861afdc50326b2f2a1b8b" title="Return the width of the knob.">knobWidth()</a>.</p>
<ul>
<li>width &gt; 0 The diameter of the knob is fixed and the knob is aligned according to the <a class="el" href="class_qwt_knob.html#a68a1d38442d36cd75fa6fb7b6d6249b1">alignment()</a> flags inside of the contentsRect().</li>
<li>width &lt;= 0 The knob is extended to the minimum of width/height of the contentsRect() and aligned in the other direction according to <a class="el" href="class_qwt_knob.html#a68a1d38442d36cd75fa6fb7b6d6249b1">alignment()</a>.</li>
