Hi all,
I'm a relative newbie to IDL. I'm working on with classes right now.
I have a class which has objects as member variables. At runtime via
the famous Info structure, I find that I need to use the objects
member functions. But lo and behold, encapsulation is implemented in
IDL 5.6(I don't believe that it was implemented in 5.5...correct me if
I'm wrong).
Basically
define = { ClassA, $
ObjectB: Obj_New()}
END
the object gets defined in
ObjectB = Obj_New("ClassB")
And somewhere we define ObjectA
ObjectA = Object_New("ClassA)
and now in an event handler far far away
Sinfo.objectA.objectB->member function
doesnt' work because we cannot access Objects A's member variables
only member functions.
I have to add a great number objects to this class. Now, there are
tons of workarounds. We can create, member functions in Class A to
access all of class B functions, but this solution is creates a great
deal of redundancy, and will make the class rather unmanageable.
Common blocks??, possible but dirty solution(i couldn't look myself in
the mirror). Is there a equivalent to the "public" keyword in C++.
So I wanted to ask the IDL gurus out there, how you overcome these
problems in very large IDL programs. I've seen lots of examples of
classes, however not one example where many are linked together and
classes are using other classes. I'm figuring there is something
simple that I am missing. Pardon the verbosity of my post, but I kept
rereading what I wrote and I couldn't understand what I was
saying...:)
Thanks a lot for the help
