Finally got some time to go back this...
I've put it back to gtk_container_add() as you (and others) recommended
and it definitely doesn't work quite right. Basically the thread is
doing this:
while(...)
{
gtk_threads_enter();
gtk_clist_append(...);
gtk_threads_leave();
}
Anyway, this doesn't update the clist correctly but adding a gdk_flush()
before the gdk_threads_leave() seems to solve this and everything is ok
(again).
I don't remember reading anything about gdk_flush() related to threads
so is there a problem somewhere or was I supposed to do that all along?
Cheers, Matt.
