Yes, but the X/Xt event loop handles "timers" (keyed off the select call) and perhaps other services that an X or Xt/Xm programmer wouldn't want to give up. Rather than handing event control to HT and telling HT to listen for X input, perhaps one could use the normal X event/input control and tell X/Xt to listen for HT input. A program can use XtAppAddInput (' not sure what the Xlib call is) to have X listen for input on an HT file descriptor, assuming one knows that file descriptor. Alternatively, and this is what I've done for the time being, one can modify HTEvent_loop to return after some number of iterations through the loop. The loop can be invoked at whatever frequency is needed, in response to Xt timer or work-proc callbacks. Tom
