I don't believe that there's an easy way to protect
Application.ProcessMessages from recursion unless someone is willing
to debug and patch Glib (which is used not only by Qt, but also from
GTK, if I'm not wrong).
A snippet from gmain.c:
#if 0
/* If recursing, finish up current dispatch, before starting over */
if (context->pending_dispatches)
{
if (dispatch)
g_main_dispatch (context, ¤t_time);
UNLOCK_CONTEXT (context);
return TRUE;
}
#endif
It would appear that they realized the dispatch recursion problems but
where unable to find a clean solution!
This code appears both in glib-2.28.8 (the one coming with CentOs 6,
which I've been using) and in the current version i.e. glib-2.47.5.
My feeling is that it's been left there as a reminder that the matter is
still pending.
I'm afraid we must live with it.
