* @note By default all positions are set as enabled.

* Signals that you can add callbacks for are:
* This widget inherits from the @ref Layout one, so that all the
* functions acting on it also work for actionslider objects.
*
* "selected" - when user selects an enabled position (the label is passed as
* event info)".
* "pos_changed" - when the indicator reaches any of the positions("left",
* "right" or "center").
* This widget emits the following signals, besides the ones sent from
* @ref Layout:
* @li @c "selected" - when user selects an enabled position (the
* label is passed as event info)".
* @li @c "pos_changed" - when the indicator reaches any of the

* Default text parts of the actionslider widget that you can use for are:
* @li "indicator" - An indicator label of the actionslider
