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 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 printf
-style format string, like "%1.2f
units"
), is meant to label the widget's progress value. Label, icon and unit strings/objects are optional for progress bars.
A progress bar may be 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 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().
This widget inherits from the Layout one, so that all the functions acting on it also work for progress bar objects.
This widget emits the following signals, besides the ones sent from Layout:
"changed"
- when the value is changed (since 1.7)"focused"
- When the progressbar has received focus. (since 1.8)"unfocused"
- When the progressbar has lost focus. (since 1.8)"language,changed"
- the program's language changed (since 1.9)
This widget has the following styles:
"default"
"wheel"
(simple style, no text, no progression, only "pulse" effect is available)
Default content parts of the progressbar widget that you can use for are:
- "icon" - An icon of the progressbar
Default text parts of the progressbar widget that you can use for are:
- "default" - A label of the progressbar

Eina_Bool elm_progressbar_pulse_get | ( | const Evas_Object * | obj | ) |
Control whether a given progress bar widget is at "pulsing mode" or not.
By default, progress bars will display values from the low to high value boundaries. There are, though, contexts in which the progress of a given task is unknown. For such cases, one can set a progress bar widget to a "pulsing state", to give the user an idea that some computation is being held, but without exact progress values. In the default theme, it will animate its bar with the contents filling in constantly and back to non-filled, in a loop. To start and stop this pulsing animation, one has to explicitly call elm_progressbar_pulse().
- Returns:
true
to putobj
in pulsing mode,false
to put it back to its default one
- Since :
- 2.3

void elm_progressbar_value_set | ( | Evas_Object * | obj, |
double | val | ||
) |
Control the progress value (in percentage) on a given progress bar widget.
