#GtkCalendar is a widget that displays a calendar, one month at a time.
|
|
It can be created with gtk_calendar_new().
|
|
</para>
|
|
<para>
|
|
The month and year currently displayed can be altered with
|
|
gtk_calendar_select_month(). The exact day can be selected from the displayed
|
|
month using gtk_calendar_select_day().
|
|
</para>
|
|
<para>
|
|
To place a visual marker on a particular day, use gtk_calendar_mark_day()
|
|
and to remove the marker, gtk_calendar_unmark_day().
|
|
Alternative, all marks can be cleared with gtk_calendar_clear_marks().
|
|
</para>
|
|
<para>
|
|
The way in which the calendar itself is displayed can be altered using
|
|
gtk_calendar_display_options().
|
|
</para>
|
|
<para>
|
|
The selected date can be retrieved from a #GtkCalendar using
|
|
gtk_calendar_get_date().
|
|
</para>
|
|
<para>
|
|
If performing many 'mark' operations, the calendar can be frozen to prevent
|
|
flicker, using gtk_calendar_freeze(), and 'thawed' again using
|
|
gtk_calendar_thaw().
