I am working on an init that pops up a dialog window when you hit a user-definable key sequence. I accomplish this by patching GetNextEvent and looking for the appropiate event in the Event Queue. If it is there, I pop-up my window. How should I go about getting subsquent events for my dialog should I manually look throught the event queue for mouse-down events and the like. Do I also need to patch WaitNextEvent or does it call GetNextEvent? Any help or tips are appreciated. Thanks In Advance.

Why do you search the Event Queue for your event in the first place. IMHO, it is better to - patch SystemEvent - wait for it to be called with your Hot Key - Do The Right Thing - return from SystemEvent indication the Hot Key had been handled. During your popup dialog, you just can call GetNextEvent. >Do I also need to patch WaitNextEvent or does it call GetNextEvent? I think it currently does. I'd like to know myself, though, how long things will stay that way.

I don't want to allow a context-switch under MultiFinder while the dialog is popped up. Can this happen if I use GetNextEvent. I remember reading something about putting some magic value in the windowkind attribute of a window to disallow a context-switch when that window was frontmost am I on the right track. Thanks for your help. John

Well, if the fronmost window is a dBoxProc (standard for Modal Dialog etc.), then GetNextEvent will disallow context switching under any normal/reasonable circumstances. -Mike Darweesh weesh@crd.ge.com
