*
* Datetime widget is used to display and input date & time values.
* This widget displays date and time as per the <b>system's locale</b> settings (Date
* includes Day, Month & Year along with the defined separators and
* Time includes Hour, Minute & AM/PM fields. Separator for AM/PM field is ignored.
*
* The corresponding Month, AM/PM strings are displayed according to the
* system’s language settings.
*
* Datetime format is a combination of LIBC standard characters like
* “%%d %%b %%Y %%I : %%M %%p” which, as a whole represents both Date as well as Time
* format.
*
* Elm_datetime supports only the following sub set of libc date format specifiers:
*
* @b %%Y : The year as a decimal number including the century (example: 2011).
*
* @b %%y : The year as a decimal number without a century (range 00 to 99)
*
* @b %%m : The month as a decimal number (range 01 to 12).
*
* @b %%b : The abbreviated month name according to the current locale.
*
* @b %%B : The full month name according to the current locale.
*
* @b %%h : The abbreviated month name according to the current locale(same as %%b).
*
* @b %%d : The day of the month as a decimal number (range 01 to 31).
*
* @b %%e : The day of the month as a decimal number (range 1 to 31). single
* digits are preceded by a blank.
*
* @b %%I : The hour as a decimal number using a 12-hour clock (range 01 to 12).
*
* @b %%H : The hour as a decimal number using a 24-hour clock (range 00 to 23).
*
* @b %%k : The hour (24-hour clock) as a decimal number (range 0 to 23). single
* digits are preceded by a blank.
*
* @b %%l : The hour (12-hour clock) as a decimal number (range 1 to 12); single
* digits are preceded by a blank.
*
* @b %%M : The minute as a decimal number (range 00 to 59).
*
* @b %%p : Either 'AM' or 'PM' according to the given time value, or the
* corresponding strings for the current locale. Noon is treated as 'PM'
* and midnight as 'AM'
*
* @b %%P : Like %p but in lower case: 'am' or 'pm' or a corresponding string for
* the current locale.
*
* @b %%c : The preferred date and time representation for the current locale.
*
* @b %%x : The preferred date representation for the current locale without the time.
*
* @b %%X : The preferred time representation for the current locale without the date.
*
* @b %%r : The complete calendar time using the AM/PM format of the current locale.
*
* @b %%R : The hour and minute in decimal numbers using the format %H:%M.
*
* @b %%T : The time of day in decimal numbers using the format %H:%M:%S.
*
* @b %%D : The date using the format %%m/%%d/%%y.
*
* @b %%F : The date using the format %%Y-%%m-%%d.
*
* (For more reference on the available <b>LIBC date format specifiers</b>, please
* visit the link:
* http://www.gnu.org/s/hello/manual/libc.html#Formatting-Calendar-Time )
*
* Datetime widget can provide Unicode @b separators in between its fields
* except for AM/PM field.
* A separator can be any <b>Unicode character</b> other than the LIBC standard
* date format specifiers.( Example: In the format %%b %%d @b , %%y %%H @b : %%M
* comma(,) is separator for date field %%d and colon(:) is separator for
* hour field %%H ).
*
* The default format is a predefined one, based on the system Locale.
*
* Hour format 12hr(1-12) or 24hr(0-23) display can be selected by setting
* the corresponding user format.
*
* Datetime supports six fields: Year, Month, Date, Hour, Minute, AM/PM.
* Depending on the Datetime module that is loaded, the user can see
* different UI to select the individual field values.
*
* The individual fields of Datetime can be arranged in any order according to the format
* set by application.
*
* There is a provision to set the visibility of a particular field as TRUE/ FALSE
* so that <b>only time/ only date / only required fields</b> will be displayed.
*
* Each field is having a default minimum and maximum values just like the daily
* calendar information. These min/max values can be modified as per the application usage.
*
* User can enter the values only in between the range of maximum and minimum.
* Apart from these APIs, there is a provision to display only a limited set of
* values out of the possible values. APIs to select the individual field limits
* are intended for this purpose.
*
* The whole widget is left aligned and its size grows horizontally depending
* on the current format and each field's visible/disabled state.
*
* Datetime individual field selection is implemented in a modular style.
* Module can be implemented as a Ctxpopup based selection or an ISE based
* selection or even a spinner like selection etc.
*
* <b>Datetime Module design:</b>
*
* The following functions are expected to be implemented in a Datetime module:
*
* <b>Field creation:</b>
* <pre>
*
* __________ __________
* | |----- obj_hook() ---------------------->>>| |
* | |<<<----------------returns Mod_data ------| |
* | Datetime |_______ | |
* | widget | |Assign module call backs | Module |
* | base |<<<____| | |
* | | | |
* | |----- field_create() ------------------>>>| |
* |__________|<<<----------------returns field_obj -----|__________|
*
* </pre>
*
* <b>Field value setting:</b>
* <pre>
*
* __________ __________
* | | | |
* | Datetime |<<<----------elm_datetime_value_set()---| |
* | widget | | Module |
* | base |----display_field_value()------------>>>| |
* |__________| |__________|
*
* </pre>
*
* <b>del_hook:</b>
* <pre>
* __________ __________
* | | | |
* | Datetime |----obj_unhook()-------------------->>>>| |
* | widget | | Module |
* | base | <<<-----frees mod_data---------| |
* |__________| |__________|
*
* </pre>
*
*
* Any module can use the following shared functions that are implemented in elm_datetime.c :
*
* <b>field_format_get()</b> - gives the field format.
*
* <b>field_limit_get()</b> - gives the field minimum, maximum limits.
*
* To enable a module, set the ELM_MODULES environment variable as shown:
*
* <b>export ELM_MODULES="datetime_input_ctxpopup>datetime/api"</b>
*
* This widget inherits from the @ref Layout one, so that all the
* functions acting on it also work for datetime objects.
*
* This widget emits the following signals, besides the ones sent from
* @ref Layout:
* @li @b "changed" - whenever Datetime field value is changed, this
* signal is sent.
* @li @b "language,changed" - whenever system locale changes, this
* signal is sent.
* @li @c "focused" - When the datetime has received focus. (since 1.8)
* @li @c "unfocused" - When the datetime has lost focus. (since 1.8)
*
* Here is an example on its usage:
* @li @ref datetime_example
