<!-- $$$QAbstractSpinBox-description -->
<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qabstractspinbox.html">QAbstractSpinBox</a> class provides a spinbox and a line edit to display values.</p>
<p>The class is designed as a common super class for widgets like <a href="qspinbox.html">QSpinBox</a>, <a href="qdoublespinbox.html">QDoubleSpinBox</a> and <a href="qdatetimeedit.html">QDateTimeEdit</a></p>
<p>Here are the main properties of the class:</p>
<ol class="1" type="1"><li><a href="qabstractspinbox.html#text-prop">text</a>: The text that is displayed in the <a href="qabstractspinbox.html">QAbstractSpinBox</a>.</li>
<li><a href="stylesheet-reference.html#alignment">alignment</a>: The alignment of the text in the <a href="qabstractspinbox.html">QAbstractSpinBox</a>.</li>
<li><a href="qabstractspinbox.html#wrapping-prop">wrapping</a>: Whether the <a href="qabstractspinbox.html">QAbstractSpinBox</a> wraps from the minimum value to the maximum value and vice versa.</li>
</ol>
<p><a href="qabstractspinbox.html">QAbstractSpinBox</a> provides a virtual <a href="qabstractspinbox.html#stepBy">stepBy</a>() function that is called whenever the user triggers a step. This function takes an integer value to signify how many steps were taken. E.g. Pressing <a href="../qtcore/qt.html#Key-enum">Qt::Key_Down</a> will trigger a call to <a href="qabstractspinbox.html#stepBy">stepBy</a>(-1).</p>
<p>When the user triggers a step whilst holding the <a href="../qtcore/qt.html#KeyboardModifier-enum">Qt::ControlModifier</a>, <a href="qabstractspinbox.html">QAbstractSpinBox</a> steps by 10 instead of making a single step. This step modifier affects wheel events, key events and interaction with the spinbox buttons. Note that on macOS, Control corresponds to the Command key.</p>
<p>Since Qt 5.12, <a href="qstyle.html#StyleHint-enum">QStyle::SH_SpinBox_StepModifier</a> can be used to select which <a href="../qtcore/qt.html#KeyboardModifier-enum">Qt::KeyboardModifier</a> increases the step rate. <a href="../qtcore/qt.html#KeyboardModifier-enum">Qt::NoModifier</a> disables this feature.</p>
<p><a href="qabstractspinbox.html">QAbstractSpinBox</a> also provide a virtual function <a href="qabstractspinbox.html#stepEnabled">stepEnabled</a>() to determine whether stepping up/down is allowed at any point. This function returns a bitset of <a href="qabstractspinbox.html#StepEnabledFlag-enum">StepEnabled</a>.</p>

<h3 class="fn" id="specialValueText-prop"><a name="specialValueText-prop"></a><span class="name">specialValueText</span> : <span class="type"><a href="../qtcore/qstring.html">QString</a></span></h3>
<p>This property holds the special-value text</p>
<p>If set, the spin box will display this text instead of a numeric value whenever the current value is equal to minimum(). Typical use is to indicate that this choice has a special (default) meaning.</p>
<p>For example, if your spin box allows the user to choose a scale factor (or zoom level) for displaying an image, and your application is able to automatically choose one that will enable the image to fit completely within the display window, you can set up the spin box like this:</p>
<pre class="cpp">
<span class="type"><a href="qspinbox.html">QSpinBox</a></span> <span class="operator">*</span>zoomSpinBox <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qspinbox.html">QSpinBox</a></span>;
zoomSpinBox<span class="operator">-</span><span class="operator">></span>setRange(<span class="number">0</span><span class="operator">,</span> <span class="number">1000</span>);
zoomSpinBox<span class="operator">-</span><span class="operator">></span>setSingleStep(<span class="number">10</span>);
zoomSpinBox<span class="operator">-</span><span class="operator">></span>setSuffix(<span class="string">"%"</span>);
zoomSpinBox<span class="operator">-</span><span class="operator">></span>setSpecialValueText(tr(<span class="string">"Automatic"</span>));
zoomSpinBox<span class="operator">-</span><span class="operator">></span>setValue(<span class="number">100</span>);
</pre>
<p>The user will then be able to choose a scale from 1% to 1000% or select "Auto" to leave it up to the application to choose. Your code must then interpret the spin box value of 0 as a request from the user to scale the image to fit inside the window.</p>
<p>All values are displayed with the prefix and suffix (if set), <i>except</i> for the special value, which only shows the special value text. This special text is passed in the <a href="qspinbox.html#valueChanged">QSpinBox::valueChanged</a>() signal that passes a <a href="../qtcore/qstring.html">QString</a>.</p>
<p>To turn off the special-value text display, call this function with an empty string. The default is no special-value text, i.e. the numeric value is shown as usual.</p>
<p>If no special-value text is set, specialValueText() returns an empty string.</p>

<p>Virtual function that is called whenever the user triggers a step. The <i>steps</i> parameter indicates how many steps were taken. For example, pressing <code>Qt::Key_Down</code> will trigger a call to <code>stepBy(-1)</code>, whereas pressing <code>Qt::Key_PageUp</code> will trigger a call to <code>stepBy(10)</code>.</p>
<p>If you subclass <code>QAbstractSpinBox</code> you must reimplement this function. Note that this function is called even if the resulting value will be outside the bounds of minimum and maximum. It's this function's job to handle these situations.</p>
