A program I am currently writing uses two string gadgets to display and
allow alteration of an (x,y) coordinate. What I want to be able to do is
to allow a mouse click in a window to also set these values.
The problem is: how do I update the string gadgets? Can I just put the
new value into the string gadgets buffer, set the longint value and refresh
them or do I have to do something else?
Thanks

Do the following: /* make the two gadgets follow each other, so you can manipulate * them with one call. That is, gad1->NextGadget=gad2. */ pos = RemoveGList( win, gad1, 2 ); /* now change buffer and LongInt */ AddGList( win, gad1, pos, 2, NULL ); RefreshGList( gad1, win, NULL, 2 ); >Michael Gordon - mfg@castle.ed.ac.uk OR ee.ed.ac.uk | |_| |_| |__| |_| | Peter -- Peter Cherna, Operating Systems Development Group, Commodore-Amiga, Inc. {uunet|rutgers}!cbmvax!peter peter@cbmvax.commodore.com My opinions do not necessarily represent the opinions of my employer.
