<p>Creates a new horizontal scale widget that lets the user input a
number between <em class="parameter"><code>min</code></em>
 and <em class="parameter"><code>max</code></em>
 (including <em class="parameter"><code>min</code></em>
 and <em class="parameter"><code>max</code></em>
) with the
increment <em class="parameter"><code>step</code></em>
.  <em class="parameter"><code>step</code></em>
 must be nonzero; it's the distance the
slider moves when using the arrow keys to adjust the scale value.</p>
<p>Note that the way in which the precision is derived works best if <em class="parameter"><code>step</code></em>

is a power of ten. If the resulting precision is not suitable for your
needs, use <a class="link" href="GtkScale.html#gtk-scale-set-digits" title="gtk_scale_set_digits ()"><code class="function">gtk_scale_set_digits()</code></a> to correct it.</p>
