+The QSlider widget provides a vertical or horizontal slider. +<p> + +<p> The slider is the classic widget for controlling a bounded value. +It lets the user move a slider along a horizontal or vertical +groove and translates the slider's position into an integer value +within the legal range. +<p> QSlider inherits <a href="qrangecontrol.html">QRangeControl</a>, which provides the "integer" side +of the slider. <a href="qrangecontrol.html#setRange">setRange</a>() and <a href="#value">value</a>() are likely to be used by +practically all slider users; see the <a href="qrangecontrol.html">QRangeControl</a> +documentation for information about the many other functions that +class provides. +<p> The main functions offered by the slider itself are tickmark and +orientation control; you can use <a href="#setTickmarks">setTickmarks</a>() to indicate where +you want the tickmarks to be, <a href="#setTickInterval">setTickInterval</a>() to indicate how +many of them you want and <a href="#setOrientation">setOrientation</a>() to indicate whether the +slider is to be horizontal or vertical. +<p> A slider accepts focus on Tab and uses the mouse wheel and a +suitable keyboard interface. +<p> <img src=qslider-m.png> <img src=qslider-w.png> +<p> +<p> <p>See also <a href="qscrollbar.html">QScrollBar</a>, <a href="qspinbox.html">QSpinBox</a>, <a

name="TickSetting-enum"></a>QSlider::TickSetting</h3> + +<p> This enum specifies where the tickmarks are to be drawn relative +to the slider's groove and the handle the user moves. +<ul> +<li><tt>QSlider::NoMarks</tt> - do not draw any tickmarks. +<li><tt>QSlider::Both</tt> - draw tickmarks on both sides of the groove. +<li><tt>QSlider::Above</tt> - draw tickmarks above the (horizontal) slider +<li><tt>QSlider::Below</tt> - draw tickmarks below the (horizontal) slider +<li><tt>QSlider::Left</tt> - draw tickmarks to the left of the (vertical) slider
