8 * @defgroup Slider Slider
11 * The slider adds a dragable “slider” widget for selecting the value of
12 * something within a range.
14 * Signals that you can add callbacks for are:
16 * changed - Whenever the slider value is changed by the user.
18 * delay,changed - A short time after the value is changed by the user.
19 * This will be called only when the user stops dragging for a very short
20 * period or when they release their finger/mouse, so it avoids possibly
21 * expensive reactions to the value change.
23 * slider,drag,start - dragging the slider indicator around has started
25 * slider,drag,stop - dragging the slider indicator around has stopped
27 * A slider can be horizontal or vertical. It can contain an Icon and has a
28 * primary label as well as a units label (that is formatted with floating
29 * point values and thus accepts a printf-style format string, like
30 * “%1.2f units”. There is also an indicator string that may be somewhere
31 * else (like on the slider itself) that also accepts a format string like
32 * units. Label, Icon Unit and Indicator strings/objects are optional.
34 * A slider may be inverted which means values invert, with high vales being
35 * on the left or top and low values on the right or bottom (as opposed to
36 * normally being low on the left or top and high on the bottom and right).
38 * The slider should have its minimum and maximum values set by the
39 * application with elm_slider_min_max_set() and value should also be set by
40 * the application before use with elm_slider_value_set(). The span of the
41 * slider is its length (horizontally or vertically). This will be scaled by
42 * the object or applications scaling factor. At any point code can query the
43 * slider for its value with elm_slider_value_get().
