<p>A spin button is a text field that accepts a range of values, with buttons that allow the value to be increased or decreased by a fixed amount.</p>

|
<p>Only use a spin button when the exact numeric value is meaningful or useful. If this isn’t the case, a <a class="reference internal" href="sliders.html"><span class="doc">slider</span></a> might be a better choice.</p>
