Introduction
The GtkCalendar widget is used to display a calendar to the screen, one month at a time. For the purpose of this example, we are not setting the date on the calendar. In a real world program, you will want to get the system date and set the date on the calendar accordingly.
Source Code
/*
*File name: calendar.c
*/#include
#include/*– This function allows the program to exit properly when the window is closed –*/
gint destroyapp (GtkWidget *widget, gpointer gdata)
{
g_print (“Quitting…\n”);
gtk_main_quit();
return (FALSE);
}int main (int argc, char *argv[])
{
/*– Declare the GTK Widgets used in the program –*/
GtkWidget *window;
GtkWidget *calendar;/*– Initialize GTK –*/
gtk_init (&argc, &argv);/*– Create the new window –*/
calendar = gtk_calendar_new();/*– Create the new window –*/
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);/*– Connect the window to the destroyapp function –*/
gtk_signal_connect(GTK_OBJECT(window), “delete_event”, GTK_SIGNAL_FUNC(destroyapp), NULL);/*– Add the calendar to the window –*/
gtk_container_add(GTK_CONTAINER(window), calendar);/*– Display the widgets –*/
gtk_widget_show(calendar);
gtk_widget_show(window);/*– Start the GTK event loop –*/
gtk_main();/*– Return 0 if exit is successful –*/
return 0;
}
