hi john,
i'm trying to set up an internal buffer for the espeak -f to work against. it workd fine iff i leave the prefix as "talk"; the instant i type into the blank space where the user enters his own name [say, 'char' or rambleon' or whstever--then the program abouts. i have also created the play button and its callback. i havent bothered with the hbox code. first: get things working. make it look nice later! o'll append y.c below and attach it also. thanks for you insights! gary On Thu, Dec 08, 2011 at 08:56:12AM +0000, jcup...@gmail.com wrote: > Return-Path: <jcup...@gmail.com> > Received: from mail-pz0-f50.google.com (mail-pz0-f50.google.com > [209.85.210.50]) by ethic.thought.org (8.14.4/8.14.4) with ESMTP id > pB88uwvn090361 for <kl...@thought.org>;
