\class QSlider
\brief The QSlider widget provides a vertical or horizontal slider.
\ingroup basicwidgets
\inmodule QtWidgets
\image windows-slider.png
The slider is the classic widget for controlling a bounded value.
It lets the user move a slider handle along a horizontal or vertical
groove and translates the handle's position into an integer value
within the legal range.
QSlider has very few of its own functions; most of the functionality is in
QAbstractSlider. The most useful functions are setValue() to set
the slider directly to some value; triggerAction() to simulate
the effects of clicking (useful for shortcut keys);
setSingleStep(), setPageStep() to set the steps; and setMinimum()
and setMaximum() to define the range of the scroll bar.
QSlider provides methods for controlling tickmarks. You can use
setTickPosition() to indicate where you want the tickmarks to be,
setTickInterval() to indicate how many of them you want. the
currently set tick position and interval can be queried using the
tickPosition() and tickInterval() functions, respectively.
QSlider inherits a comprehensive set of signals:
\table
\header \li Signal \li Description
\row \li \l valueChanged()
\li Emitted when the slider's value has changed. The tracking()
determines whether this signal is emitted during user
interaction.
\row \li \l sliderPressed()
\li Emitted when the user starts to drag the slider.
\row \li \l sliderMoved()
\li Emitted when the user drags the slider.
\row \li \l sliderReleased()
\li Emitted when the user releases the slider.
\endtable
QSlider only provides integer ranges. Note that although
QSlider handles very large numbers, it becomes difficult for users
to use a slider accurately for very large ranges.
A slider accepts focus on Tab and provides both a mouse wheel and a
keyboard interface. The keyboard interface is the following:
\list
\li Left/Right move a horizontal slider by one single step.
\li Up/Down move a vertical slider by one single step.
\li PageUp moves up one page.
\li PageDown moves down one page.
\li Home moves to the start (minimum).
\li End moves to the end (maximum).
\endlist

/*!
\enum QSlider::TickPosition
