<hr><a name="_details"></a><h2>Detailed Description</h2>
A class which controls a value within an interval.
<p>
<p>
This class is useful as a base class or a member for sliders. It represents an interval of type double within which a value can be moved. The value can be either an arbitrary point inside the interval (see <a class="el" href="class_qwtdblrange.html#a7">QwtDblRange::setValue</a>), or it can be fitted into a step raster (see <a class="el" href="class_qwtdblrange.html#a1">QwtDblRange::fitValue</a> and <a class="el" href="class_qwtdblrange.html#a2">QwtDblRange::incValue</a>).
<p>
As a special case, a QwtDblRange can be periodic, which means that a value outside the interval will be mapped to a value inside the interval when <a class="el" href="class_qwtdblrange.html#a7">setValue</a>(), <a class="el" href="class_qwtdblrange.html#a1">fitValue</a>(), <a class="el" href="class_qwtdblrange.html#a2">incValue</a>() or <a class="el" href="class_qwtdblrange.html#a3">incPages</a>() are called.
