integer value within a
range.</p>
<p>The class is designed as a common super class for widgets like
<a href="qscrollbar.html">QScrollBar</a>, <a href="qslider.html">QSlider</a> and <a href="qdial.html">QDial</a>.</p>
<p>Here are the main properties of the class:</p>
<ol class="1">
<li><a href="qabstractslider.html#value-prop">value</a>: The
bounded integer that QAbstractSlider maintains.</li>
<li><a href="qabstractslider.html#minimum-prop">minimum</a>: The
lowest possible value.</li>
<li><a href="qabstractslider.html#maximum-prop">maximum</a>: The
highest possible value.</li>
<li><a href="qabstractslider.html#singleStep-prop">singleStep</a>:
The smaller of two natural steps that an abstract sliders provides
and typically corresponds to the user pressing an arrow key.</li>
<li><a href="qabstractslider.html#pageStep-prop">pageStep</a>: The
larger of two natural steps that an abstract slider provides and
typically corresponds to the user pressing PageUp or PageDown.</li>
<li><a href="qabstractslider.html#tracking-prop">tracking</a>:
Whether slider tracking is enabled.</li>
<li><a href="qabstractslider.html#sliderPosition-prop">sliderPosition</a>: The
current position of the slider. If <a href="qabstractslider.html#tracking-prop">tracking</a> is enabled (the
default), this is identical to <a href="qabstractslider.html#value-prop">value</a>.</li>
</ol>
<p>Unity (1) may be viewed as a third step size. <a href="qabstractslider.html#value-prop">setValue</a>() lets you set the
current value to any integer in the allowed range, not just
<a href="qabstractslider.html#minimum-prop">minimum</a>() +
<i>n</i> * <a href="qabstractslider.html#singleStep-prop">singleStep</a>() for integer
values of <i>n</i>. Some widgets may allow the user to set any
value at all; others may just provide multiples of <a href="qabstractslider.html#singleStep-prop">singleStep</a>() or <a href="qabstractslider.html#pageStep-prop">pageStep</a>().</p>
<p>QAbstractSlider emits a comprehensive set of signals:</p>
<table class="generic">
<thead>
<tr class="qt-style">
<th>Signal</th>
<th>Emitted when</th>
</tr>
</thead>
<tr class="odd" valign="top">
<td><a href="qabstractslider.html#valueChanged">valueChanged</a>()</td>
<td>the value has changed. The <a href="qabstractslider.html#tracking-prop">tracking</a> determines
whether this signal is emitted during user interaction.</td>
</tr>
<tr class="even" valign="top">
<td><a href="qabstractslider.html#sliderPressed">sliderPressed</a>()</td>
<td>the user starts to drag the slider.</td>
</tr>
<tr class="odd" valign="top">
<td><a href="qabstractslider.html#sliderMoved">sliderMoved</a>()</td>
<td>the user drags the slider.</td>
</tr>
<tr class="even" valign="top">
<td><a href="qabstractslider.html#sliderReleased">sliderReleased</a>()</td>
<td>the user releases the slider.</td>
</tr>
<tr class="odd" valign="top">
<td><a href="qabstractslider.html#actionTriggered">actionTriggered</a>()</td>
<td>a slider action was triggerd.</td>
</tr>
<tr class="even" valign="top">
<td><a href="qabstractslider.html#rangeChanged">rangeChanged</a>()</td>
<td>a the range has changed.</td>
</tr>
</table>
<p>QAbstractSlider provides a virtual <a href="qabstractslider.html#sliderChange">sliderChange</a>() function
that is well suited for updating the on-screen representation of
sliders. By calling <a href="qabstractslider.html#triggerAction">triggerAction</a>(),
subclasses trigger slider actions. Two helper functions <a href="qstyle.html#sliderPositionFromValue">QStyle.sliderPositionFromValue</a>()
and <a href="qstyle.html#sliderValueFromPosition">QStyle.sliderValueFromPosition</a>()
help subclasses and styles to map screen coordinates to logical
range values.</p>
