Hello world!
I am a beginning Mac programmer and am writing a DA for my first project.
I am running into a problem that is probably rather trivial for most of
you out there, so I'd appreciate a hint.
In the Open procedure, I need to make the following calls:
InitGraf(@thePort)
InitFonts;
TEInit;
(That is, I need to use some TextEdit routines, so I need TEInit, which
in turn needs the other two calls; at least, that is what I think I am
reading). Besides, I will need to use QuickDraw later on, so it seems
best to initialize it at the beginning.
The problem I am running into is that thePort is a QD Global variable
and global variables are not allowed in a DA (or so everyone tells me).
It is obvious that there is a way around this -- there are many DA's
out there using QD. Can someone please show me the way?
Thanks in advance,

DON'T CALL THE Init calls from a DA!! If an application is to support
DAs, there are quite explicit rules as to what it must do. All Mac
programs which can support DAs have already caled InitGraf. I guarantee
that. The should have also Inited everything you will need. See the Desk
Manager stuff for that.
So the moral is to not call InitGraf & friends from a DA.
