[Yes, I know, everything on the NeXT is backwards :-)] > >What I want to do is something like: > > [NXApp pushCursor:NXWait]; // save current cursor, put up wait > ... time-consuming code -- > [NXApp popCursor]; // restore cursor Cursor's push and pop methods are the way to go; essentially you need to do: #import <appkit/Cursor.h> -methodWhichTakesALongTime:sender { [NXWait push]; ... [NXWait pop]; return self; } To do what you want, you can add the pushCursor: and popCursor methods to your subclass of Application; it's trivial enough if you use the knowledge that you can send "pop" to any cursor, not the one you pushed (This is a feature that will most probably work all the time.): - pushCursor:cursor { [cursor push]; return self; } - popCursor { [NXArrow pop]; // Doesn't matter what cursor, so you can // get away with this... return self; } Ali Ozer, NeXT Developer Support Ali_Ozer@NeXT.com >From: ramsdell@linus.UUCP (John D.
