You usualy dont need it,
    generaly your main loop is `gtk_main();',
`gtk_events_pending();' is often used when processing large
datasets in your ui (i.e. before threads we're supported in gtk
or when you're too lazy to implement them) like so:
============================================================
void
crunch_large_dataset_button_clicked(GtkButton *button,
                                    gpointer user_data)
{
    /* ... */
    for (element in list of large data set) {
        data_crunching();
        /* This effectivly "nests" the main loop so that your
         * UI stays responsive during this callback.
         */
        while (gtk_events_pending()) {
            gtk_main_iteration_do(FALSE);
/*

*/
        }
    }
}
