- * @defgroup Slider Slider
- * @ingroup Elementary
- *
- * The slider adds a dragable “slider” widget for selecting the value of
- * something within a range.
- *
- *
- * A slider can be horizontal or vertical. It can contain an Icon and has a
- * primary label as well as a units label (that is formatted with floating
- * point values and thus accepts a printf-style format string, like
- * “%1.2f units”. There is also an indicator string that may be somewhere
- * else (like on the slider itself) that also accepts a format string like
- * units. Label, Icon Unit and Indicator strings/objects are optional.
- *
- * A slider may be inverted which means values invert, with high vales being
- * on the left or top and low values on the right or bottom (as opposed to
- * normally being low on the left or top and high on the bottom and right).
- *
- * The slider should have its minimum and maximum values set by the
- * application with elm_slider_min_max_set() and value should also be set by
- * the application before use with elm_slider_value_set(). The span of the
- * slider is its length (horizontally or vertically). This will be scaled by
- * the object or applications scaling factor. At any point code can query the
- * slider for its value with elm_slider_value_get().
- *
- * Signals that you can add callbacks for are:
- *
- * "changed" - Whenever the slider value is changed by the user.
- * "slider,drag,start" - dragging the slider indicator around has started
- * "slider,drag,stop" - dragging the slider indicator around has stopped
- * "delay,changed" - A short time after the value is changed by the user.
- * This will be called only when the user stops dragging for
- * a very short period or when they release their
- * finger/mouse, so it avoids possibly expensive reactions to
- * the value change.
