4 * The progress bar is a widget for visually representing the
5 * progress status of a given job/task.
7 * A progress bar may be horizontal or vertical. It may display an
8 * icon besides it, as well as primary and @b units labels. The
9 * former is meant to label the widget as a whole, while the
10 * latter, which is formatted with floating point values (and thus
11 * accepts a <c>printf</c>-style format string, like <c>"%1.2f
12 * units"</c>), is meant to label the widget's <b>progress
13 * value</b>. Label, icon and unit strings/objects are @b optional
17 * A progress bar may be @b inverted, in which state it gets its
18 * values inverted, with high values being on the left or top and
19 * low values on the right or bottom, as opposed to normally have
20 * the low values on the former and high values on the latter,
21 * respectively, for horizontal and vertical modes.
23 * A progress bar may be @b inverted, in which case it gets its
24 * values inverted, i.e., high values being on the left or top and
25 * low values on the right or bottom, for horizontal and vertical modes
27 >>>>>>> remotes/origin/upstream
29 * The @b span of the progress, as set by
30 * elm_progressbar_span_size_set(), is its length (horizontally or
31 * vertically), unless one puts size hints on the widget to expand
32 * on desired directions, by any container. That length will be
34 * scaled by the object or applications scaling factor. At any
35 * point code can query the progress bar for its value with
37 * scaled by the object or applications scaling factor.
38 * Applications can query the progress bar for its value with
39 >>>>>>> remotes/origin/upstream
40 * elm_progressbar_value_get().
42 * Available widget styles for progress bars:
44 * - @c "wheel" (simple style, no text, no progression, only
45 * "pulse" effect is available)
47 * Default text parts of the progressbar widget that you can use for are:
49 * @li "default" - Label of the progressabar
51 * Default contents parts of the progressbar widget that you can use for are:
53 * @li "default" - Label of the progressbar
55 * Default content parts of the progressbar widget that you can use for are:

57 * @li "icon" - An icon of the progressbar

88 * @param pulse @c EINA_TRUE to put @p obj in pulsing mode,
89 * @c EINA_FALSE to put it back to its default one
91 * By default, progress bars will display values from the low to
92 * high value boundaries. There are, though, contexts in which the
94 * state of progression of a given task is @b unknown. For those,
95 * one can set a progress bar widget to a "pulsing state", to give
96 * the user an idea that some computation is being held, but
