It wasn't intuitive, but scroll to mark doe the trick, the following
func append to a textview (a log actually) and scrolls:
void scacpg_append_runlog(char * msg, ...)
{
GtkTextView * eview;
GtkTextBuffer * ebuf;
GtkTextIter start, end;
va_list ap;
char * buffer = NULL;
int l, L = 128;
GtkTextMark* mark;
va_start(ap, msg);
do {
L *= 2;
debug("realloc of log buffer to size %d", L);
buffer = realloc(buffer, L);
l = vsnprintf(buffer, L, msg, ap);
if (l < 0) return;
} while (l >= L);
eview = (GtkTextView* ) lookup_widget(dialog_run,
"textview_cpg_output");
ebuf = gtk_text_view_get_buffer (eview);
debug ("runlog: %s(%d)", buffer, l);
gtk_text_buffer_get_bounds (ebuf, &start, &end);
gtk_text_buffer_insert (ebuf, &end, buffer, l);
gtk_text_buffer_get_bounds (ebuf, &start, &end);
mark = gtk_text_buffer_create_mark (ebuf, NULL, &end, 1);
gtk_text_view_scroll_to_mark(eview, mark, 0.0, 0, 0.0, 1.0);
gtk_text_buffer_delete_mark (ebuf, mark);
free(buffer);
va_end(ap);
};
