如何在运行时将页面添加到Gtk Notebook小部件？

GtkWidget *notebook = gtk_notebook_new();
gtk_notebook_set_tab_pos(GTK_NOTEBOOK(notebook), GTK_POS_TOP);

GtkWidget *label = gtk_label_new("New Page");

gtk_notebook_append_page(GTK_NOTEBOOK(notebook), label, gtk_label_new("Page Title"));

void add_page(GtkNotebook *notebook, GtkWidget *page_widget, const gchar *page_title) {
    gtk_notebook_append_page(notebook, page_widget, gtk_label_new(page_title));
}
