API¶

Events¶

Change: Called when the date property is changed.

Properties¶

date DAY, MONTH, YEAR

Accepts three integers in format of "localtime". DAY can be from 1 to 31, MONTH from 0 to 11, YEAR from 0 to 199.

Default value: today's date.

day INTEGER

Selects the day in month.

firstDayOfWeek INTEGER

Selects the first day of week, an integer between 0 and 6, where 0 is Sunday is the first day, 1 is Monday etc.

Default value: 0

month

Selects the month.

useLocale BOOLEAN

If 1, the locale-specific names of months and days of week are used. These are read by calling "POSIX::strftime". If invocation of POSIX module fails, the property is automatically assigned to 0.

If 0, the English names of months and days of week are used.

Default value: 1

Methods¶

can_use_locale

Returns boolean value, whether the locale information can be retrieved by calling "strftime".

month2str MONTH

Returns MONTH name according to useLocale value.

make_months

Returns array of 12 month names according to useLocale value.

day_of_week DAY, MONTH, YEAR, [ USE_FIRST_DAY_OF_WEEK = 1 ]

Returns integer value, from 0 to 6, of the day of week on DAY, MONTH, YEAR date. If boolean USE_FIRST_DAY_OF_WEEK is set, the value of "firstDayOfWeek" property is taken into the account, so 0 is a Sunday shifted forward by "firstDayOfWeek" days.

The switch from Julian to Gregorian calendar is ignored.

date_as_string [ DAY, MONTH, YEAR ]

Returns string representation of date on DAY, MONTH, YEAR according to useLocale property value.

date_from_time SEC, MIN, HOUR, M_DAY, MONTH, YEAR, ...

Copies date from "localtime" or "gmtime" result. This helper method allows the following syntax:

        $calendar-> date_from_time( localtime( time));
