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 case it gets its
17 * values inverted, i.e., high values being on the left or top and
18 * low values on the right or bottom, for horizontal and vertical modes
21 * The @b span of the progress, as set by
22 * elm_progressbar_span_size_set(), is its length (horizontally or
23 * vertically), unless one puts size hints on the widget to expand
24 * on desired directions, by any container. That length will be
25 * scaled by the object or applications scaling factor.
26 * Applications can query the progress bar for its value with
27 * elm_progressbar_value_get().
29 * Available widget styles for progress bars:
31 * - @c "wheel" (simple style, no text, no progression, only
32 * "pulse" effect is available)
34 * Default text parts of the progressbar widget that you can use for are:
35 * @li "default" - Label of the progressbar
37 * Default content parts of the progressbar widget that you can use for are:
38 * @li "icon" - An icon of the progressbar
40 * Supported elm_object common APIs.
41 * @li elm_object_part_text_set
42 * @li elm_object_part_text_get
43 * @li elm_object_part_content_set

52 * Add a new progress bar widget to the given parent Elementary
55 * @param parent The parent object
56 * @return a new progress bar widget handle or @c NULL, on errors
58 * This function inserts a new progress bar widget on the canvas.

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