5 * @defgroup Progressbar Progressbar
7 * The progressbar adds a widget for representing current progress
10 * A progressbar can be horizontal or vertical. It can contain an Icon and has a
11 * primary label as well as a units label (that is formatted with floating
12 * point values and thus accepts a printf-style format string, like
15 * Label, Icon and Unit strings/objects are optional.
17 * A progressbar may be inverted which means values invert, with high vales being
18 * on the left or top and low values on the right or bottom (as opposed to
19 * normally being low on the left or top and high on the bottom and right).
21 * The span of the progressbar is its length (horizontally or vertically).
22 * This will be scaled by the object or applications scaling factor. At any point
23 * code can query the progressbar for its value with elm_progressbar_value_get().
