#include <gtk/gtk.h>

int
main(int argc, char *argv[])
{
    GtkWidget *window, *button;

    gtk_init(&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);

    button = gtk_check_button_new();
    /* Do not accept focus, also prevents changing by keyboard */
    g_object_set(button, "can-focus", FALSE, 0);
    /* Do not respond to mouse events */
    g_signal_connect(button, "button-press-event", G_CALLBACK(gtk_true), NULL);
    g_signal_connect(button, "button-release-event", G_CALLBACK(gtk_true), NULL);
    /* Do not change appearance on mouseover */
    g_signal_connect(button, "enter-notify-event", G_CALLBACK(gtk_true), NULL);
    g_signal_connect(button, "leave-notify-event", G_CALLBACK(gtk_true), NULL);

    gtk_container_add(GTK_CONTAINER(window), button);
    gtk_widget_show_all(window);
    gtk_main();

    return 0;
