34
 
A class which controls a value within an interval. 
35
 
<p>
36
 
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_qwt_double_range.html#f6a3aa74c970a2bef29f0c1af99720e8">QwtDoubleRange::setValue</a>), or it can be fitted into a step raster (see <a class="el" href="class_qwt_double_range.html#63bc8ea5e7ecd776b7d32d21db1ea668">QwtDoubleRange::fitValue</a> and <a class="el" href="class_qwt_double_range.html#299c35c72e9b69f5a0e3dcd2b7da775b">QwtDoubleRange::incValue</a>).<p>
37
 
As a special case, a <a class="el" href="class_qwt_double_range.html">QwtDoubleRange</a> 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_qwt_double_range.html#f6a3aa74c970a2bef29f0c1af99720e8">QwtDoubleRange::setValue()</a>, <a class="el" href="class_qwt_double_range.html#63bc8ea5e7ecd776b7d32d21db1ea668">QwtDoubleRange::fitValue()</a>, <a class="el" href="class_qwt_double_range.html#299c35c72e9b69f5a0e3dcd2b7da775b">QwtDoubleRange::incValue()</a> or <a class="el" href="class_qwt_double_range.html#19b85337d4ab0b5f0579b02e4fb29a8f">QwtDoubleRange::incPages()</a> are called.
