* @brief The check widget allows for toggling a value between true

*
* Check objects are a lot like radio objects in layout and functionality
* except they do not work as a group, but independently and only toggle the
* value of a boolean from false to true (0 or 1). elm_check_state_set() sets
* the boolean state (1 for true, 0 for false), and elm_check_state_get()
* returns the current state. For convenience, like the radio objects, you
* can set a pointer to a boolean directly with elm_check_state_pointer_set()
* for it to modify.

* Signals that you can add callbacks for are:
* "changed" - This is called whenever the user changes the state of the check
* objects(event_info is NULL).
* This widget inherits from the @ref Layout one, so that all the
* functions acting on it also work for check objects.
*
* This widget emits the following signals, besides the ones sent from
* @ref Layout:
* - @c "changed" - This is called whenever the user changes the state of
* the check objects (@c event_info is always @c NULL).
*
* Default content parts of the check widget that you can use for are:
* @li "icon" - An icon of the check
