I have been playing with the TinyEdit sample that came with THINK C 4.0. I have tried and failed to find keyUp events in CSwitchboard::ProcessEvent(). I test for them right after WaitNextEvent which is called with everyEvent=0xFFFF. Can anyone suggest what might be wrong? -- Jennings Jennings via cmhGate - Net 226 fido<=>uucp gateway Col, OH UUCP: ...!osu-cis!n8emr!cmhgate!343!31!Jennings.Jennings INET: Jennings.Jennings@f31.n343.z1.FIDONET.ORG

There is a system event mask in low memory which is initialized to accept all events EXCEPT keyUp events. This is because most apps don't care about when the keys are released, and keyUp events would "crowd out" other more important events in the queue. You can set the system event mask by calling SetEventMask (see IM II, p.70). Greg Marriott Blue Meanie Apple Computer, Inc.

Inside Mac Vol I page 256: NOTE: Remember that most applications will want to ignore Key-Up events; with the standard system event mask you won't get any.

SetEventMask(everyEvent); /* enables KeyUp */ or SysEvtMask = everyEvent; of course, you'll want to save the old mask and restore it when you don't need the change ... -dave- hairston@henry.ece.cmu.edu
