Read the Gtk+ FAQ, Qt FAQ, whatever. You'll need to make only one thread use X (Gtk+/Qt) calls, or use semaphores to protect against using X from two threads at the same moment. > I'm open to suggestions here ... as I'm fresh out. I'm using threads, works fine. If you want to use signal()/read(), go for gdk_input_add()/g_source_add() without threads. In any case, show us some code that we can comment on.
