You call sleep() in mainloop causes it block, you can use
g_timeout_*() functions to create event in mainloop in timely manner.
Below I modify your code to implement g_timeout_*() functions.
Note, you must care with subwindow creation, user may still create the
subwindow (by clicking the OK button) although the subwindow is still
displayed.
gboolean destroy_subwindow(GtkWidget *subwindow)
{
gtk_widget_destroy(subwindow);
return FALSE;
}
void subroutine(GtkWidget *button, gpointer data)
{
GtkWidget *subwindow, *label;
subwindow=gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_default_size(GTK_WINDOW(subwindow), 400, 50);
label=gtk_label_new("Label");
gtk_container_add(GTK_CONTAINER(subwindow),label);
gtk_widget_show_all(subwindow);
g_timeout_add (5000, (GSourceFunc) destroy_subwindow, subwindow);
/* while (g_main_context_iteration(NULL, FALSE)); */
/* sleep(5); */
/* gtk_widget_destroy(subwindow); */
return;
}
