2 * @defgroup Progressbar Progress bar
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
16 * A progress bar may be @b inverted, in which state it gets its
17 * values inverted, with high values being on the left or top and
18 * low values on the right or bottom, as opposed to normally have
19 * the low values on the former and high values on the latter,
20 * respectively, for horizontal and vertical modes.
22 * The @b span of the progress, as set by
23 * elm_progressbar_span_size_set(), is its length (horizontally or
24 * vertically), unless one puts size hints on the widget to expand
25 * on desired directions, by any container. That length will be
26 * scaled by the object or applications scaling factor. At any
27 * point code can query the progress bar for its value with
28 * elm_progressbar_value_get().
30 * Available widget styles for progress bars:
32 * - @c "wheel" (simple style, no text, no progression, only
33 * "pulse" effect is available)
35 * Default contents parts of the progressbar widget that you can use for are:
36 * @li "icon" - An icon of the progressbar
38 * Here is an example on its usage:
39 * @li @ref progressbar_example
43 * Add a new progress bar widget to the given parent Elementary
46 * @param parent The parent object
47 * @return a new progress bar widget handle or @c NULL, on errors
49 * This function inserts a new progress bar widget on the canvas.

56 * Set whether a given progress bar widget is at "pulsing mode" or
59 * @param obj The progress bar object
60 * @param pulse @c EINA_TRUE to put @p obj in pulsing mode,
61 * @c EINA_FALSE to put it back to its default one
63 * By default, progress bars will display values from the low to
64 * high value boundaries. There are, though, contexts in which the
65 * state of progression of a given task is @b unknown. For those,
66 * one can set a progress bar widget to a "pulsing state", to give
67 * the user an idea that some computation is being held, but
68 * without exact progress values. In the default theme it will
69 * animate its bar with the contents filling in constantly and back
70 * to non-filled, in a loop. To start and stop this pulsing
71 * animation, one has to explicitly call elm_progressbar_pulse().
