You need a break at the end of each case, otherwise all events would be
treated as SELECTION_REQUEST_EVENT.

    case FOCUS_IN_EVENT: ignore_event = Qfocus_in; break;

I think something like this should work:

    listn (CONSTYPE_PURE, 6, Qfocus_in, Qfocus_out, Qhelp, Qiconify, 
Qdeiconify, Qselection_request);
