## Description

The `gtk.Calendar` is a widget that displays a simple calendar, one month at a time. In addition, the calendar can display the days of the week and navigation controls that allow a user to change the month and year displayed by calling the `display_options`() (`set_display_options`() in PyGTK 2.4 and above) method. The possible display options are:

`gtk.CALENDAR_SHOW_HEADING` | Specifies that the month and year should be displayed.
`gtk.CALENDAR_SHOW_DAY_NAMES` | Specifies that three letter day descriptions should be present.
`gtk.CALENDAR_NO_MONTH_CHANGE` | Prevents the user from switching months with the calendar.
`gtk.CALENDAR_SHOW_WEEK_NUMBERS` | Displays each week numbers of the current year, down the left side of the calendar.
`gtk.CALENDAR_WEEK_START_MONDAY` | Starts the calendar week on Monday, instead of the default Sunday.

The month and year currently displayed are programatically changed by calling the `select_month`() method. The exact day is selected from the displayed month using the `select_day`() method.

To place a visual marker on a particular day, use the `mark_day`() method and to remove the marker, the `unmark_day`() method. All marks are cleared by calling the `clear_marks`() method.

The selected date can be retrieved from a `gtk.Calendar` using the `get_date`() method. If performing many 'mark' operations, the calendar can be frozen to prevent flicker, using the `freeze`() method, and 'thawed' again using the `thaw`() method.

### Note

Note that month is zero-based (i.e it allowed values are 0-11) while selected_day is one-based (i.e. allowed values are 1-31).

## Constructor

        gtk.Calendar()

Returns : | a calendar object

Creates a calendar object that displays the current month and year with the current day selected. The default calendar display style is: gtk.CALENDAR_SHOW_HEADING | gtk.CALENDAR_SHOW_DAY_NAMES that shows the days of the week and the month and year heading with navigation controls.

## Methods

### gtk.Calendar.select_month

        def select_month(month, year)

`month` : | the new month number between 0 and 11
`year` : | the new year number
Returns : | True if the month is set

The `select_month`() method changes the calendar display to the specified `month` and `year`.

### gtk.Calendar.select_day

        def select_day(day)

`day` : | the new day number between 1 and 31 - 0 removes the current selection

The `select_day`() method selects the specified `day` on the calendar when `day` has a value between 1 and 31. If `day` is 0 then the current day selection is removed.

### gtk.Calendar.mark_day

        def mark_day(day)

`day` : | the number of the day to be marked
Returns : | True

The `mark_day`() method marks the specified month `day` with a visual marker (typically by making the number bold). If the calendar month and year are changed the marked days remain marked.

### gtk.Calendar.unmark_day

        def unmark_day(day)

`day` : | the number of the day to be unmarked
Returns : | True

The `unmark_day`() method unmarks the specified month `day`.

### gtk.Calendar.clear_marks

        def clear_marks()

The `clear_marks`() method clears all marked days.

### gtk.Calendar.get_display_options

        def get_display_options()

Returns : | the calendar display options

### Note

This method is available in PyGTK 2.4 and above.

The `get_display_options`() method returns the current calendar display options. See the `set_display_options`() method for more information.

### gtk.Calendar.set_display_options

        def set_display_options(flags)

`flags` : | the new calendar display options

### Note

This method is available in PyGTK 2.4 and above.

The `set_display_options`() method sets the calendar display options to the value specified by `flags`. The possible display options are a combination of:

`gtk.CALENDAR_SHOW_HEADING` | Specifies that the month and year should be displayed.
`gtk.CALENDAR_SHOW_DAY_NAMES` | Specifies that three letter day descriptions should be present.
`gtk.CALENDAR_NO_MONTH_CHANGE` | Prevents the user from switching months with the calendar.
`gtk.CALENDAR_SHOW_WEEK_NUMBERS` | Displays each week numbers of the current year, down the left side of the calendar.
`gtk.CALENDAR_WEEK_START_MONDAY` | Starts the calendar week on Monday, instead of the default Sunday.

The display options can be removed by passing 0 as the value of `flags`.

### gtk.Calendar.get_detail_height_rows

        def get_detail_height_rows()

Returns : | The height of detail cells, in rows.

### Note

This method is available in PyGTK 2.14 and above.

The `get_detail_height_rows`() method queries the height of detail cells, in rows. See the "detail-width-chars" property.

### gtk.Calendar.set_detail_height_rows

        def set_detail_height_rows(rows)

`rows` : | detail height in rows.

### Note

This method is available in PyGTK 2.14 and above.

The `set_detail_height_rows`() method updates the height of detail cells. See the "detail-height-rows" property.

### gtk.Calendar.get_detail_width_chars

        def get_detail_width_chars()

Returns : | The width of detail cells, in characters.

### Note

This method is available in PyGTK 2.14 and above.

The `get_detail_width_chars`() method queries the width of detail cells, in characters. See the "detail-width-chars" property.

### gtk.Calendar.set_detail_width_chars

        def set_detail_width_chars(chars)

`chars` : | detail width in characters.

### Note

This method is available in PyGTK 2.14 and above.

The `set_detail_width_chars`() method updates the width of detail cells. See the "detail-width-chars" property.

### gtk.Calendar.display_options

        def display_options(flags)

`flags` : | the new calendar display options

### Warning

This method is deprecated in PyGTK 2.4 and should be replaced by the `set_display_options`() method.

The `display_options`() method sets the calendar display options to the value specified by `flags`. The possible display options are a combination of:

`gtk.CALENDAR_SHOW_HEADING` | Specifies that the month and year should be displayed.
`gtk.CALENDAR_SHOW_DAY_NAMES` | Specifies that three letter day descriptions should be present.
`gtk.CALENDAR_NO_MONTH_CHANGE` | Prevents the user from switching months with the calendar.
`gtk.CALENDAR_SHOW_WEEK_NUMBERS` | Displays each week numbers of the current year, down the left side of the calendar.
`gtk.CALENDAR_WEEK_START_MONDAY` | Starts the calendar week on Monday, instead of the default Sunday.

The display options can be removed by passing 0 as the value of `flags`.

### gtk.Calendar.get_date

        def get_date()

Returns : | a tuple containing the year, month and day

The `get_date`() method retrieves the calendar's current year, month and selected day numbers as a tuple (year, month, day).

### Note

Note that month is zero-based (i.e it allowed values are 0-11) while selected_day is one-based (i.e. allowed values are 1-31).

### gtk.Calendar.freeze

        def freeze()

The `freeze`() method stops the update of the calendar display until the `thaw`() method is called. This method is used to reduce calendar flicker when doing a large number of updates to the calendar.

### gtk.Calendar.thaw

        def thaw()

The `thaw`() method reenables the update of the calendar after a `freeze`() method is called. All changes made since the last `freeze`() are displayed
