It can be created with gtk_calendar_new(). * * 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(). * * 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(). * * The way in which the calendar itself is displayed can be altered using * gtk_calendar_set_display_options(). * * The selected date can be retrieved from a #GtkCalendar using * gtk_calendar_get_date(). * * Users should be aware that, although the Gregorian calendar is the * legal calendar in most countries, it was adopted progressively * between 1582 and 1929. Display before these dates is likely to be * historically incorrect. */ #include "config.h" #ifdef HAVE_SYS_TIME_H #include #endif #ifdef HAVE__NL_TIME_FIRST_WEEKDAY #include #endif #include #include #include #include #ifdef G_OS_WIN32 #include #endif #include "gtkcalendar.h" #include "gtkdragdest.h" #include "gtkintl.h" #include "gtkmain.h" #include "gtkmarshalers.h" #include "gtktooltip.h" #include "gtkprivate.h" #include "gtkrendericonprivate.h" #include "gtksnapshot.h" #include "gtkstylecontextprivate.h" #include "gtkwidgetprivate.h" #include "gtkgestureclick.h" #include "gtkgesturedrag.h" #include "gtkeventcontrollerscroll.h" #include "gtkeventcontrollerkey.h" #include "gtkdragsource.h" #include "gtknative.h" #include "gtkicontheme.h" #include "gtkdragicon.h" #include "gtkbutton.h" #include "gtkbox.h" #include "gtklabel.h" #include "gtkstack.h" #define TIMEOUT_INITIAL 500 #define TIMEOUT_REPEAT 50 static const guint month_length[2][13] = { { 0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 }, { 0, 31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 } };
