+ * @defgroup Progressbar Progress bar
+ * @ingroup Elementary
+ *
+ * The progress bar is a widget for visually representing the
+ * progress status of a given job/task.
+ *
+ * A progress bar may be horizontal or vertical. It may display an
+ * icon besides it, as well as primary and @b units labels. The
+ * former is meant to label the widget as a whole, while the
+ * latter, which is formatted with floating point values (and thus
+ * accepts a <c>printf</c>-style format string, like <c>"%1.2f
+ * units"</c>), is meant to label the widget's <b>progress
+ * value</b>. Label, icon and unit strings/objects are @b optional
+ * for progress bars.
+ *
+ * A progress bar may be @b inverted, in which case it gets its
+ * values inverted, i.e., high values being on the left or top and
+ * low values on the right or bottom, for horizontal and vertical modes
+ * respectively.
+ *
+ * The @b span of the progress, as set by
+ * elm_progressbar_span_size_set(), is its length (horizontally or
+ * vertically), unless one puts size hints on the widget to expand
+ * on desired directions, by any container. That length will be
+ * scaled by the object or applications scaling factor.
+ * Applications can query the progress bar for its value with
+ * elm_progressbar_value_get().
+ *
+ * Available widget styles for progress bars:
+ * - @c "default"
+ * - @c "wheel" (simple style, no text, no progression, only
+ *      "pulse" effect is available)
+ *
+ * Default text parts of the progressbar widget that you can use for are:
+ * @li "default" - Label of the progressbar
+ *
+ * Default content parts of the progressbar widget that you can use for are:
+ * @li "icon" - An icon of the progressbar
+ *
+ * Supported elm_object common APIs.
+ * @li @ref elm_object_part_text_set
